Daniel Ken Inouye (/iːˈnoʊˌeɪ/ ee-NOH-ay,^[1] Japanese: 井上 建,^[2] September 7, 1924 – December 17, 2012) was an American attorney, soldier, and politician who served as a United States senator from Hawaii from 1963 until his death in 2012. A Medal of Honor recipient, Inouye began his political career in territorial government. In 1959 he was elected as the first U.S. Representative for the State of Hawaii. A member of the Democratic Party, he also served as the president pro tempore of the United States Senate from 2010 until his death.^[3] Inouye was the highest-ranking Asian-American politician in U.S. history^[4] until Kamala Harris was elected as vice president in 2020.^[5] Inouye also chaired various Senate committees, including those on Intelligence, Indian Affairs, Commerce, and Appropriations.

Inouye fought in World War II as part of the 442nd Infantry Regiment. He lost his right arm to a grenade wound and received several military decorations, including the Medal of Honor (the nation's highest military award). Inouye later earned a J.D. degree from George Washington University Law School.

Returning to Hawaii, Inouye was elected to Hawaii's territorial House of Representatives in 1953, and was elected to the territorial Senate in 1957. When Hawaii achieved statehood in 1959, Inouye was elected as its first member of the House of Representatives. He was first elected to the U.S. Senate in 1962. He never lost an election in 58 years as an elected official, and he exercised an exceptionally large influence on Hawaii politics.

At the time of his death, Inouye was the last remaining U.S. Senator to have served during the presidencies of John F. Kennedy, Lyndon B. Johnson, and Richard Nixon.

Inouye was the second Asian American senator, following Hawaii Republican Hiram Fong. Inouye was the first Japanese American to serve in the U.S. House of Representatives, and the first to serve in the U.S. Senate. Because of his seniority, Inouye became president pro tempore of the Senate following the death of Robert Byrd on June 28, 2010, making him third in the presidential line of succession after the Vice President and the Speaker of the House of Representatives.

Inouye was a posthumous recipient of the Presidential Medal of Freedom and the Order of the Paulownia Flowers. Among other public structures, Honolulu International Airport has since been renamed Daniel K. Inouye International Airport in his memory.

Daniel Ken Inouye was born in Honolulu, Territory of Hawaii on September 7, 1924.^[6] His father, Hyotaro Inouye, was a jeweler^[7] who had immigrated to Hawaii from Japan as a child.^[8] His mother, Kame (née Imanaga) Inouye, was a homemaker^[7] born on Maui to Japanese immigrants.^[9] Her parents died young and she was adopted and raised by a family in Honolulu. Both of Daniel's parents were Christian, and met at the River Street Methodist Church in Honolulu. They married in 1923.^[6] This heritage makes Daniel a Nisei (second-generation Japanese-American) through his father and a Sansei (third-generation) through his mother. Daniel was named after Kame's adoptive father.^[6]

Inouye grew up in Bingham Tract, a Chinese-American enclave in Honolulu.^[10] He was raised Christian,^[11] and was the oldest of four children.^[12] As a child, Inouye collected homing pigeons, which were hatched from eggs given to him at an army base in Schofield Barracks in return for Inouye cleaning the coops. As a teenager, he worked on the local beaches teaching tourists how to surf.^[13] Inouye's parents raised him and his siblings with a mix of American and Japanese customs. His parents spoke English at home, but had their children attend a private Japanese language school in addition to public school.^[14] Inouye dropped out of the Japanese school in 1939 because he disagreed with his instructor's anti-American rhetoric, and focused on his studies at President William McKinley High School.^[15] Inouye intended to go to college and medical school after his planned 1942 graduation.^[16]

Inouye witnessed the attack on Pearl Harbor on December 7, 1941, while still a high school senior.^[17] The Japanese surprise attack brought the United States into World War II. Being a volunteer first aid instructor with the Red Cross, he was called on by his supervisor to report to a Red Cross station set up at Lunalilo Elementary School.^[18] There, Inouye tended to civilians injured by antiaircraft shells that had fallen into the city. After the United States declared war on Japan the next day, Inouye took up a paid job from his Red Cross supervisor to work there as a medical aide. For the rest of his senior year, Inouye attended school during the day, and worked at the Red Cross station at night.^[19] He graduated from McKinley High School in 1942.^[20]

Although Inouye wanted to join the armed forces after graduating, Japanese-Americans had been excluded. The United States Department of War had declared all Japanese-Americans as "enemy aliens", which stipulated they could not volunteer or be drafted for military service.^[21] Inouye enrolled at the University of Hawaiʻi at Mānoa in September 1942 as a premedical student with the goal of becoming a surgeon.^[21]

In March 1943, U.S. President Franklin D. Roosevelt established the 442nd Regimental Combat Team, an all-Nisei combat unit. Inouye applied and was initially turned down because his work at the Red Cross was deemed critical, but was inducted later that month.^[22] The unit was composed of over 2,500 Nisei from Hawaii, and 800 from the mainland. Inouye went with his unit in April to Camp Shelby in Mississippi for a 10-month training period, postponing his medical studies.^[22] While in Mississippi, the unit visited the Rohwer War Relocation Center in Arkansas, where Inouye witnessed the internment of Japanese Americans first hand.^[23]

The 442nd shipped off to Italy in May 1944 after the conclusion of their training,^[24] shortly before the liberation of Rome.^[25] Inouye was promoted to sergeant within the first three months of fighting in the Italian countryside north of Rome.^[26][25] The 442nd was then sent to eastern France, where they seized the towns of Bruyères, Belmont, and Biffontaine from the Germans.^[26] In late October, the regiment was transferred to the Vosges Mountains region of France, where they rescued 211 members of the 1st Battalion of the 141st Infantry Regiment, otherwise known as the "Lost Battalion".^[26] Inouye received a battlefield commission to second lieutenant for his actions there, becoming the youngest officer in his regiment.^[27][25] During the battle, a shot struck him in the chest directly above his heart, but the bullet was stopped by the two silver dollars he happened to have stacked in his shirt pocket.^[28] He continued to carry the coins throughout the war in his shirt pocket as good luck charms, but lost them later, shortly before the battle in which he lost his arm.^[29] The 442nd spent the next several months near Nice, guarding the French-Italian border until early 1945, when they were called to Northern Italy to assist with an assault on German strongholds in the Apennine Mountains.^[27]

On April 21, 1945, Inouye was grievously wounded while leading an assault on the heavily defended Colle Musatello ridge near San Terenzo, Italy. The ridge served as a strongpoint of the German fortifications known as the Gothic Line, the last and most unyielding line of German defensive works in Italy. During a flanking maneuver against German machine gun nests, Inouye was shot in the stomach from 40 yards away. Ignoring his wound, Inouye proceeded with the attack and together with the unit, destroyed the first two machine gun nests. As his squad distracted the third machine gunner, the injured Inouye crawled toward the final bunker and came within 10 yards. As he prepared to toss a grenade within, a German soldier fired out a 30 mm Schiessbecher antipersonnel rifle grenade at Inouye, striking Inouye in the right elbow. Although it failed to detonate, the blunt force of the grenade amputated most of his right arm at the elbow. The nature of the injury caused Inouye's arm muscles to involuntarily squeeze the grenade tightly via a reflex arc, preventing his arm from going limp and dropping a live grenade at his feet. This injury left Inouye disabled, in terrible pain, under fire with minimal cover and staring at a live grenade "clenched in a fist that suddenly didn't belong to me anymore."^[30]

Inouye's platoon moved to his aid, but Inouye shouted for them to keep back out of fear his severed fist would involuntarily relax and drop the grenade. As the German inside the bunker began reloading his rifle with regular full metal jacket ammunition to finish off Inouye, Inouye pried the live hand grenade from his useless right hand with his left, and tossed it into the bunker, killing the German. Stumbling to his feet, Inouye continued forward, killing at least one more German before sustaining his fifth and final wound of the day in his left leg. Inouye fell unconscious, and awoke to see the worried men of his platoon hovering over him. His only comment before being carried away was to gruffly order them back to their positions, saying "Nobody called off the war!"^[31] By the end of the day, the ridge had fallen to American control, without the loss of any soldiers in Inouye's platoon.^[32] The remainder of Inouye's mutilated right arm was later amputated at a field hospital without proper anesthesia, as he had been given too much morphine at an aid station and it was feared any more would lower his blood pressure enough to kill him.^[33] The war in Europe ended on May 8, less than three weeks later.^[32]

Shortly before the Japanese surrender and end of World War II in August 1945, Inouye was shipped back to the United States to recover for eleven months at a rehabilitation center for wounded soldiers in Atlantic City, New Jersey.^[32] In mid-1946, Inouye was transferred to the Percy Jones Army Hospital in Battle Creek, Michigan, to continue his rehabilitation for nine more months.^[32] While recovering there, Inouye met future Republican senator and presidential candidate Bob Dole, then a fellow patient.^[32] The two became friends and would often play bridge together. Dole shared with Inouye his long-term plans to attend law school and become an attorney, and later run for state legislature and eventually the United States Congress. With Inouye's plans to become a surgeon dashed due to his injury, Dole's plans for a career in public service inspired Inouye to consider entering politics.^[34] Inouye ultimately beat Dole to congress. The two remained lifelong friends. In 2003, the hospital was renamed the Hart–Dole–Inouye Federal Center in honor of the two World War II veterans, as well as Democratic senator Philip Hart, who had been a patient at the hospital after sustaining injuries on D-Day.^[35]

Inouye was honorably discharged with the rank of captain in May 1947 after 20 months of rehabilitation.^[36] At the time, he was a recipient of the Bronze Star Medal,^[37] Distinguished Service Cross, and three Purple Hearts.^[32] Many in his regiment believed that, were he not Japanese-American, he would have been awarded the Medal of Honor, the nation's highest military award.^[32] Inouye eventually received the Medal of Honor on June 21, 2000, from President Bill Clinton, along with 19 other Japanese American servicemen in the 442nd.^[38][39]

Inouye decided to study law hoping it would lead him into a political career.^[40] He enrolled at the University of Hawaiʻi at Mānoa in late 1947 as a prelaw student, majoring in government and economics.^[41] Inouye relied on the financial benefits of the G.I. Bill to fund his education.^[41] When not in class, he volunteered for the Democratic Party at the Honolulu County Democratic Committee. Inouye had been talked into joining the party by John A. Burns, a former police captain and future governor, who had ties to the Japanese American community. Though the territory of Hawaii had been politically dominated by the Republican Party, Burns convinced Inouye that the Democratic Party could help Japanese Hawaiians achieve social and economic reform.^[41] During these years, Inouye met speech instructor Margaret Awamura at the university, whom he married in 1948.^[40]

After graduating in 1950, Inouye moved with his wife to Washington D.C. so he could continue his studies at George Washington University Law School.^[40] While there, Inouye volunteered at the Democratic National Committee (DNC) headquarters to gain more experience to bring back with him to Hawaii.^[40] Inouye earned his J.D. degree in two years, and moved back with his wife to Hawaii in late 1952.^[40] Inouye spent the next year studying for the Hawaii bar exam and volunteering with the Democratic Party. After passing the bar exam in August 1953, Inouye was appointed assistant public prosecutor for the city and county of Honolulu by the city mayor and fellow Democrat John Wilson.^[42]

At the urging of Burns, Inouye successfully ran for the Hawaii Territorial House of Representatives in the November 1954 election, representing the Fourth District.^[43] The election came to be known as the Hawaii Democratic Revolution of 1954, as the long-entrenched Republican control of the Hawaii Territorial Legislature abruptly ended with a wave of Democratic candidates taking their seats. The election also filled the legislature with Japanese-American politicians, who previously held few seats.^[44] Inouye was immediately elected majority leader. He served two terms there, and was elected to the Hawaii territorial senate in 1957. Midway through Inouye's first term, Hawaii achieved statehood. He won a seat in the U.S. House of Representatives as Hawaii's first full member, and took office August 21, 1959, the same date Hawaii became a state. Inouye was re-elected in 1960.

In 1962, Inouye was elected to the U.S. Senate, succeeding retiring fellow Democrat Oren E. Long.

Inouye was the chairman of the Senate Intelligence Committee between 1976 and 1979 and the chairman of the Senate Indian Affairs Committee between 1987 and 1995. He introduced the National Museum of the American Indian Act in 1984 which led to the inauguration of the National Museum of the American Indian in 2004. Inouye was chairman of the Senate Indian Affairs Committee between 2001 and 2003, chairman of the Senate Commerce Committee between 2007 and 2009, and chairman of the Senate Appropriations Committee between 2009 and 2012.

Inouye was reelected eight times, usually without serious difficulty. His closest race was in 1992, when state senator Rick Reed held Inouye to 57 percent of the vote; this was the only time he received less than 69 percent of the vote. Inouye delivered the keynote address at the turbulent 1968 Democratic National Convention in Chicago^[45] and gained national attention for his service on the Senate Watergate Committee.

Inouye was also involved in the Iran-Contra investigations of the 1980s, chairing a special committee (Senate Select Committee on Secret Military Assistance to Iran and the Nicaraguan Opposition) from 1987 until 1989. During the hearings, Inouye referred to the operations that had been revealed as a "secret government", saying:

[There exists] a shadowy Government with its own Air Force, its own Navy, its own fundraising mechanism, and the ability to pursue its own ideas of the national interest, free from all checks and balances, and free from the law itself.^[46]

— Daniel Inouye

Criticizing the logic of Marine Lt. Colonel Oliver North's justifications for his actions in the affair, Inouye made reference to the Nuremberg trials, provoking a heated interruption from North's attorney Brendan Sullivan, an exchange that was widely repeated in the media at the time. He was also seen as a pro-Taiwan senator and helped in forming the Taiwan Relations Act.

On May 1, 1977, Inouye stated that President Carter had telephoned him to express his objections to a sentence in the Senate Intelligence Committee's report on the Central Intelligence Agency.^[47]

On November 20, 1993, Inouye voted against the North American Free Trade Agreement.^[48] The trade agreement linked the United States, Canada, and Mexico into a single free trade zone and was signed into law on December 8 by President Bill Clinton.^[49]

In 2009, Inouye assumed leadership of the powerful Senate Committee on Appropriations after longtime chairman Robert Byrd stepped down. Following the latter's death on June 28, 2010, Inouye was elected President pro tempore, the officer third in the presidential line of succession. Inouye was the highest an Asian American had reached in the line of succession until the Vice-Presidency of Kamala Harris.

In 2010, Inouye announced his decision to run for a ninth term.^[50] He easily won the Democratic primary—the real contest in heavily Democratic Hawaii — and then won against Republican state representative Campbell Cavasso with 74 percent of the vote.

Inouye ran for Senate Majority Leader several times without success.^[51]

Prior to his death, Inouye announced that he planned to run for a record tenth term in 2016 when he would have been 92 years old.^[52][53] Inouye also said,

I have told my staff and I have told my family that when the time comes, when you question my sanity or question my ability to do things physically or mentally, I don't want you to hesitate, do everything to get me out of here, because I want to make certain the people of Hawaii get the best representation possible.^[54]

In 1986, West Virginia Senator Robert Byrd opted to run for Senate Majority Leader, believing that his two opponents to claiming the position would be Inouye and Louisiana Senator J. Bennett Johnston. Cutting a deal with Inouye, Byrd pledged that he would step aside from the position in 1989 if Inouye supported him for Senate Majority Leader of the 100th United States Congress. Inouye accepted the offer and was given the chance to select the new Senate sergeant-at-arms.^[55]

In early 1981, Inouye called for tighter restrictions on what Americans can ship overseas, citing his belief that American international stature would be harmed along with the country's foreign policy interests in the event of the shipments causing environmental damage.^[56]

In March 1981, Inouye was one of 24 elected officials to issue a joint statement calling on the Reagan administration to compose a method of finding a peaceful solution that would end The Troubles in Northern Ireland.^[57]

In July 1981, a Federal commission began hearings to decide on rewarding compensations to Japanese-Americans placed in internment camps during World War II, Inouye and fellow Hawaii Senator Spark M. Matsunaga delivering opening statements.^[58] In November, during an appearance at the opening of a 10-day public forum at Tufts University on Japanese internment, Inouye stated his opposition to distributing reparation fees for Japanese-Americans previously incarcerated during World War II, adding that it "would be insulting even to try to do so."^[59] In August 1988, Inouye attended President Reagan's signing of legislation apologizing for the internment camps and establishing a $1.25 billion trust fund to pay reparations to both those who were placed in camps and to their families.^[60] In September 1989, during the Senate's debate over bestowing reparations to Japanese-Americans interned during World War II, Inouye delivered his first public speech on the issue and noted $22,000 were bestowed to each captive American in the Iran hostage crisis.^[61]

In October 2002, Inouye was one of 23 senators who voted against authorization of the use of military force in Iraq.^[62]

In March 1982, amid controversy surrounding Democratic Senator Harrison A. Williams' taking bribes in the Abscam sting operation,^[63] Inouye delivered a closing defense argument stating the possibility of the Senate looking foolish in the event the conviction was reversed on appeal. Inouye confirmed that he had received telephone calls regarding Williams critiquing his remarks during his defense of himself the previous week and questioned if the Senate was going to punish him "because his presentation was rambling, not in the tradition of Daniel Webster" and for his wife believing in him.^[64]

In October 1982, after President Reagan appointed two new members to the board of the Legal Services Corporation, Inouye was one of 32 Senators to sign a letter expressing grave concerns over the appointments.^[65]

On December 23, Inouye voted against^[66] a 5 cent a gallon increase in gasoline taxes across the U.S. imposed to aid the financing of highway repairs and mass transit. The bill passed on the last day of the 97th United States Congress.^[67][68]

In March 1984, Inouye voted against a constitutional amendment authorizing periods in public schools for silent prayer^[69] and against President Reagan's unsuccessful proposal for a constitutional amendment permitting organized school prayer in public schools.^[70][71] In August, Inouye secured the acceptance of the Senate's defense appropriations subcommittee for an amendment meant to cure mainland milk arriving at Hawaiian and Alaskan military bases sour, arguing thousands of gallons of milk coming from the mainland must be dumped due to their souring and said shipments were arriving eight days after pasteurization.^[72]

In February 1989, after Oliver North went on trial in Federal District Court amid accusations that he illegally diverted profits from the secret sale of arms to Iran to the Nicaraguan rebels, Jack Brooks, then-chair of the House Oversight Committee, questioned North's role in composing a "contingency plan in the event of an emergency that would suspend the American Constitution." Inouye replied that the inquiry touched on a classified and sensitive matter that would only be discussed in a closed session.^[73]

In 1992, Inouye's hairdresser made allegations of sexual misconduct initiating with a 1975 incident wherein she was placed on an errand to his apartment, which he denied.^[74] Although reaching press nationally, consensus was that Hawaii's culture of silence towards indiscretions of those in power, prevailed.^[75][76] A Senate ethics committee review was dropped in 1993 over lack of participation or refusal to be publicly identified by accusers.^[77]

In 2014, two years after Inouye's death, senator Kirsten Gillibrand from New York wrote in her autobiography about a male colleague who squeezed her waist and commented: "Don't lose too much weight now. I like my girls chubby!" Although not named in the autobiography, The New York Times identified Inouye as the perpetrator, setting off national discussion of Inouye's past.^{[78][79][80][81][82][83]} In 2017, discussion resurfaced in local Hawaii media about the power of Inouye, and hence deference given to him politically and publicly, with the #MeToo movement providing impetus for just one more of the nine accusers coming forward publicly.^[84][85] The former staffer told about how Inouye initiated with asking her to rub his shoulders in his office, continuing with him later trying to put his hand on her leg once when in an automobile. When she tried to stop him, he grabbed her hand. During a trip to the 1988 Democratic National Convention in Atlanta, after a late-night simulcast to Hawaii, he asked her if she was hungry, and offered her a ride, inviting her to a late dinner in his room. Upon arriving in the room, he requested she sit next to him on the bed. She complied but immediately stood away, and called a fellow female staffer to join her there. Shortly thereafter, Inouye tried to bring his hand under her skirt while the two were riding together in an automobile; the staffer thwarted Inouye's advances with her hand. The corroborator of her story requested to remain anonymous.^[86]

A state lawmaker, who learned about the 1992 accusations through a PBS television program, questioned the 2016 renaming of the Honolulu International Airport after Inouye. They declined seeking the renaming while receiving criticism from within and outside the Hawaii Democratic party for labeling Inouye as "an accused serial rapist."^[87][88]

On May 23, 2005, Inouye was a member of a bipartisan group of 14 moderate senators, known as the Gang of 14, to forge a compromise on the Democrats' use of the judicial filibuster, thus blocking the Republican leadership's attempt to implement the "nuclear option", a means of forcibly ending a filibuster.^[89] Under the agreement, the Democrats would retain the power to filibuster a Bush judicial nominee only in an "extraordinary circumstance", and the three most conservative Bush appellate court nominees (Janice Rogers Brown, Priscilla Owen, and William H. Pryor Jr.) would receive a vote by the full U.S. Senate.^[90]

Inouye never lost an election.^[91]

In August 1968, President Lyndon B. Johnson placed a phone call to vice president and Democratic presumptive presidential nominee Hubert Humphrey, urging him to select Inouye as his running mate.^[92] Johnson went as far as to request a background check on Inouye from the Federal Bureau of Investigation.^[93] Johnson told Humphrey that Inouye's World War II injuries would silence Humphrey's critics on the Vietnam War: "He answers Vietnam with that empty sleeve. He answers your problems with (Republican presumptive presidential nominee and former vice president Richard) Nixon with that empty sleeve", Johnson said.^[92] Humphrey eventually chose Edmund Muskie as his running mate, and lost the election.^[94] According to his chief of staff, Jennifer Sabas, Inouye knew that he was being considered as a vice presidential pick, but was uninterested in the possibility, apparently content with his current position.^[95]

Inouye's first wife was Margaret "Maggie" Shinobu Awamura, who was working as a speech instructor at the University of Hawaiʻi when Inouye was attending as a prelaw student after the war. The two married on June 12, 1948, at the Harris Memorial Methodist Church in Honolulu.^[40] She died of cancer on March 13, 2006. On May 24, 2008, Inouye married Irene Hirano in a private ceremony in Beverly Hills, California. Hirano was president and founding chief executive officer of the Japanese American National Museum in Los Angeles, California. She resigned the position at the time of her marriage, in order to be closer to her husband. According to the Honolulu Advertiser, Inouye was 24 years older than Hirano. On May 27, 2010, Hirano was elected chair of the nation's second largest non-profit organization, The Ford Foundation.^[96] Hirano outlived him by more than seven years; she died on April 7, 2020.^[97]

Inouye's son, Kenny, was the guitarist for the hardcore punk band Marginal Man.^[98]

He was later elected to the Hawaii Territorial House of Representatives, the United States House of Representatives, and the United States Senate. Senator Inouye was the first Japanese American to serve in Congress, representing the people of Hawaii from the moment they joined the Union.^[112]

On May 27, 1947, Inouye was honorably discharged and returned home as a Captain with a Distinguished Service Cross, Bronze Star Medal, two Purple Hearts, and 12 other medals and citations. In 2000, his Distinguished Service Cross was upgraded to the Medal of Honor.^{[113][114][115]}

In 2012, Inouye began using a wheelchair in the Senate to preserve his knees, and received an oxygen concentrator to aid his breathing. In November 2012, Inouye sustained a minor cut after falling in his apartment and was treated at Walter Reed National Military Medical Center.^[116] On December 6, he was again hospitalized at George Washington University Hospital so doctors could further regulate his oxygen intake, and was transferred to Walter Reed Medical Center four days later.
