Biden's Personal Doctor Summoned Amid GOP Investigation into Alleged Cognitive Decline Cover-Up
Congress subpoenas Biden's doctor to testify on alleged concealment of mental fitness issues on June 27.

Amid mounting questions over former President Joe Biden’s cognitive health, the House Committee on Oversight and Government Reform has issued a subpoena for Biden’s longtime personal physician, Dr. Kevin O’Connor, compelling him to testify on June 27. The move comes as lawmakers intensify investigations into allegations of a cover-up surrounding Biden’s mental fitness during his presidency and the circumstances under which he exercised major executive powers—including controversial pardons—toward the end of his administration.
Committee Chairman Rep. James Comer, R-Ky., emphasized the gravity of the inquiry, pointedly noting that “no autopen was used in the signing of this subpoena,” referencing criticism of Biden’s use of mechanized signatures for official documents. Comer’s remarks underscore the committee’s insistence on transparency after Dr. O’Connor declined an earlier invitation for a voluntary interview and was reportedly blocked from testifying by the White House regarding both Biden’s medical records and his potential involvement with the wider Biden family’s business dealings.
The subpoena explicitly questions whether O’Connor’s longstanding ties with the Biden family could have influenced his assessments of the president’s physical and mental capacities. “Given your connections with the Biden family, the Committee sought to understand if you contributed to an effort to hide former President Biden’s fitness to serve from the American people,” it states. These concerns have been amplified in light of Biden’s recent prostate cancer diagnosis following his departure from office—a period marked by renewed scrutiny over his cognitive abilities among both major political parties.
Throughout Biden’s tenure, Dr. O’Connor provided the public with annual reports attesting to the president’s overall good health. As Biden’s physician since 2009, O’Connor has described the former president as an honorable leader and a deeply genuine person, emphasizing their close professional relationship. Despite these reassurances, calls for O’Connor to speak directly to Congress and the public intensified in spring 2024 as speculation about Biden’s mental acuity reached peak levels, with many demanding a full, transparent account from the president’s chief medical adviser.
The coming deposition is expected to shed light on the nature of Dr. O’Connor’s medical oversight and whether there was any undue influence or deliberate withholding of information regarding President Biden’s health. As the investigation gains traction, the testimony of Biden’s trusted physician may play a critical role in determining the extent of transparency—or possible concealment—surrounding the president’s mental and physical condition during one of the most consequential periods of recent American political history.
