Mikkanen was a federal judicial nominee for more than 10 months in 2011, but his nomination immediately encountered opposition from Oklahoma's congressional delegation. The nomination languished without a hearing before the United States Senate Committee on the Judiciary, and the White House ultimately nominated another candidate for that judgeship.^[3] Mikkanen was recommended for the judgeship on the United States District Court for the Northern District of Oklahoma by Democratic Governor Brad Henry.^[4] On February 2, 2011, President Barack Obama formally nominated Mikkanen to a seat on the Northern District of Oklahoma that had been vacated by Judge Terence C. Kern, who had taken senior status in January 2010.^[2][5][6] Mikkanen's nomination was immediately met with opposition from members of Oklahoma's congressional delegation, with Republican Senators Jim Inhofe and Tom Coburn and Democratic Representative Dan Boren expressing disappointment that they were not consulted on the nomination.^[7][8] However, an official in Obama White House speaking off the record disputed that they did consult with the Oklahoma congressional delegation.^[8] Public opposition to Mikkanen's nomination has centered around procedural grounds rather than substantive issues about Mikkanen himself.^[7][8]

Had he been confirmed, Mikkanen would have been only the third Native American ever to serve on the federal bench, after Frank Howell Seay and Michael Burrage.^[8][9] His nomination was returned to the President on December 17, 2011, pursuant to the rules of the Senate, and Obama did not renominate Mikkanen to the judgeship.^[3] In February 2012, Obama nominated John E. Dowdell to fill the vacancy, and the Senate confirmed Dowdell to the seat in December 2012.^[10]
