Failed nomination to district court under Obama
On April 14, 2016, President Barack Obama nominated O'Sullivan to serve as a United States district judge of the United States District Court for the Western District of Washington, to the seat vacated by Judge Marsha J. Pechman, who took senior status on February 6, 2016. That nomination expired on January 3, 2017, with the end of the 114th Congress.

Renomination to district court under Trump
On July 13, 2018, President Donald Trump announced his intention to re-nominate O'Sullivan to serve as a United States district judge of the United States District Court for the Western District of Washington. President Trump was to nominate O'Sullivan to the same seat. However, due to a dispute with the state's U.S. Senators over the nomination of Eric D. Miller, O'Sullivan's nomination was never submitted to the Senate.
