He was nominated to the seat vacated by Judge James H. Payne, who assumed senior status on August 1, 2017.[8] On July 11, 2018, a hearing on his nomination was held before the Senate Judiciary Committee.[9] During his hearings Senator Kamala Harris said the Judiciary Committee should not have moved forward with O'Connor's nomination before the ABA released its rating.[10] Although O'Connor had received the highest Martindale-Hubbell anonymous peer review ratings for ethics and competence since 1995 and had been included on the "legal dream team" chosen by anonymously surveyed leading regional lawyers, judges and business leaders,[11] the American Bar Association's Standing Committee on the Federal Judiciary unanimously rated O'Connor "not qualified" on August 21, 2018, citing the ABA committee's concerns about professional competence (on the specific basis that he lacked experience trying criminal law matters and citing time elapsed since he had last litigated a federal jury trial) and integrity (mentioning a dismissed lawsuit over fees).[12][13][14] The ABA assessment cited a process involved more than fifty interviews conducted and analyzed by two ABA committee reviewers (the ABA letter does not break out the results of such interviews quantitatively, but specifically the opinion of one anonymous interviewee).[15] On January 3, 2019, his nomination was returned to the President under Rule XXXI, Paragraph 6 of the United States Senate. He withdrew from consideration for renomination, despite the support of both of Oklahoma's Senators.[16][17]

On June 27, 2022 O'Connor announced a $250 million settlement recovery from three opioid manufacturers operating in the state, with the settlement money to be used to prevent and treat opioid addiction.[30] In August 2022, 61 lawmakers urged O'Connor to support death row inmate Richard Glossip's request for a new hearing. "Without support from O'Connor, the Court of Criminal Appeals is expected to reject Glossip's claims of innocence, as it has done before."[31]
