A few days after his inauguration, President Joe Biden announced that he would appoint O'Connor as the White House physician. His predecessor, Sean Conley, was physician to previous president Donald Trump and departed the White House alongside Trump on January 20, 2021.[11]
On July 21, 2022, O'Connor diagnosed Biden with COVID-19 and prescribed him with Paxlovid.[12] There was commentary on O'Connor not briefing the White House Press Corps during Biden's illness, instead communicating through memoranda addressed to the White House press secretary, Karine Jean-Pierre.[6]
On July 7, 2024, James Comer, chair of the House Oversight Committee, sent a letter to O'Connor to ask him to come testify. Comer wants him to testify on Biden's health, due to Biden's poor performance at the June 2024 presidential debate with Donald Trump, and how it could be connected to alleged business dealings with the Biden family.[13]
On July 17, 2024, O'Connor diagnosed Biden with COVID-19 and prescribed him with Paxlovid.[14]
