Dr. O’Connor insists Biden is in “excellent” shape to finish out his term, and finds no reason to test him for cognitive functioning as many prominent doctors have recommended. “We don’t need to. He’s here every day,” he told a reporter last month in an impromptu interview at the White House, echoing Biden’s reasoning that the daily performance of his duties is proof enough of his mental acuity.

Growing numbers of people are questioning his medical judgment because O’Connor is much more than a doctor to the president. Records show that he is also a longtime friend, personal adviser, political donor, former paid campaign worker, and even a business consultant to the Biden family.

A former White House physician who attended to both Barack Obama and Donald Trump claims O’Connor has been trying to “cover up” Biden’s deteriorating condition to appease the first family, with whom he’s formed a tight bond over the past 15 years.

“Kevin O’Connor was in that job on Day One of the Biden administration because they knew they could trust Kevin to say and do anything that needed to be said or done, and cover up whatever needed to be covered up,” Dr. Ronny Jackson, now a Republican congressman, said in a recent interview. “He is part of the Biden family.”
