The White House doctor who previously gave President Joe Biden a clean bill of health is a longtime family friend — as speculation of a cover-up over his new cancer diagnosis continues to ramp up.
Dr. Kevin O’Connor served as the 82-year-old’s official physician during his White House stint — and repeatedly insisted for years that Biden was in top mental shape despite his obvious cognitive decline.
Now, in the wake of Biden’s prostate cancer diagnosis, O’Connor’s longstanding relationship with the Biden clan has come under renewed scrutiny.
O’Connor — a former Army surgeon who Biden affectionately refers to as “Doc” — has been caring for the former president and other members of his family for more than a decade.
The loyal physician also has business ties to Biden’s young brother, Jim Biden, after the pair worked closely on a rural hospital venture.
In that instance, O’Connor engaged in business discussions with James for a since-bankrupted rural hospital chain that was later hit with fraud allegations by the Securities and Exchange Commission and Justice Department.
O’Conner worked with Biden during his vice presidency, too.
After more than two decades in the Army, O’Connor joined the White House Medical Unit under then-President George W. Bush. He was only supposed to serve six months with the new vice president, Biden, but ended up staying on for years.
“That didn’t work out and, so, I ended up doing the whole eight years with him,” O’Connor joked in a rare 2023 interview with the New York Institute of Technology College of Osteopathic Medicine.
He retired when Obama and Biden left office, but remained on as Biden’s personal physician. He was brought back as the top White House doctor when Biden was elected president.
He was also a sounding board for the family before Biden’s eldest son, Beau, died of brain cancer in 2015.
O’Connor had counseled Beau on treatment options and his prognosis, according to Biden’s memoir, “Promise Me Dad.”
Critics have, in the past, criticized the close relationship between the doctor and former prez — with Rep. Ronny Jackson (R-Texas) telling The Post just last month that “he’s part of the Biden family.”
“He would do or say anything to cover up and protect that family, regardless of what it meant professionally for him,” Jackson said at the time.
President Trump, for his part, honed in on O’Connor’s prior positive health assessments just after the cancer diagnosis came to light.
Trump pointed to how the doctor had given Biden the all-clear during their last physical in February 2024 — just months before the public saw his diminished capabilities on full display during their first presidential debate.
“If it’s the same doctor that said there’s nothing wrong there, and that’s being proven to be a very sad situation,” Trump said Monday.
“I think someone is going to have to speak to his doctor.”
It comes after Biden’s office announced Sunday that he’d been diagnosed with stage 4 prostate cancer.
The cancer, which was detected after doctors found a “small nodule” on his prostate during a medical exam earlier this month, had since spread to the bone, according to his spokesperson.
