House Committee on Oversight and Accountability Chairman James Comer is investigating President Joe Biden's physician, Dr. Kevin O'Connor, to determine if his ties to the Biden family's financial activities influenced his medical assessments of Biden. Concerns about Biden's health, especially after a poor debate performance, have led to calls for transparency regarding O'Connor's evaluations. O'Connor's previous assessment deemed Biden fit for duty despite public observations of physical struggles, raising questions about the thoroughness of the examinations. The committee is also looking into O'Connor's alleged involvement with the Biden family's business dealings, particularly with a defunct healthcare company linked to Biden's brother. The investigation aims to ensure the independence and accuracy of medical evaluations in light of Biden's age and cognitive abilities, amid growing doubts about his leadership capabilities and reelection prospects.
