A top Fox News personality stunned the viewing audience on Friday with her commentary concerning former President Joe Biden’s physician, Dr. Kevin O’Connor, being subpoenaed to testify before Congress. She also made jaw-dropping claims about President Donald Trump’s health.

During a segment with Kayleigh McEnany discussing Biden’s decline, Fox commentator Marie Harf said, “Well, what’s interesting is those quotes you read generally refer to physical health. We all saw Biden’s physical health deteriorating in front of us.”

“And mental,” one of the panel’s guests says.

Harf replied, “That’s a separate question. And I have not seen evidence presented by a doctor or someone else that would say that Joe Biden was not mentally able to do the job.”

McEnany fired back, “Did you watch the debate?” in a reference to the first presidential debate of the 2024 election between then-presidential candidate Trump and former President Biden. Experts agree, on both sides of the aisle, that Biden’s performance was disastrous and revealed he was unfit for another term.

Suttering angrily, Harf replied, “That’s a different issue, Kayleigh,” before saying, “That’s not a mental issue.”

Things quickly spiraled further and further out of control for Harf from there. Next, she suggested that President Trump had health issues similar to those of Biden, which set McEnany off.

While Harf may claim not to have seen any evidence from someone she deems “credible,” there is plenty of it in existence nonetheless.

One such example comes from February 2024 when the report from Special Counsel Robert Hur described Biden’s memory as “hazy,” “fuzzy,” “faulty,” and “poor,” pointing out “significant limitations.” During interviews with Hur, Biden reportedly had difficulty recalling key life events, like the date of his son Beau’s death or when he served as vice president during the Obama administration.

Audio tapes of the interviews were obtained by media outlet Axios, which revealed Biden struggling to recall when President Donald Trump was first elected and why he had classified documents in his possession. Ultimately, according to Hur, these cognitive issues are why the former president wasn’t prosecuted for having the documents.

CNN anchor Jake Tapper and Axios reporter Alex Thompson recently released a book called “Original Sin,” which features many incidents in which Biden failed to recognize longtime acquaintances and required assistance when attending public events.

Biden also showed signs of physical deterioration as well. In June 2023, the former president stumbled over a sandbag at a graduation ceremony for the U.S. Air Force Academy.

A Secret Service agent also recalled a time when Biden was disoriented and went into a closet believing it was a hallway.
