Former first lady Jill Biden should have to answer for her role in the “cover up” of her husband and former President Joe Biden’s mental decline, according to White House Press Secretary Karoline Leavitt. 

Multiple books published in 2025 have detailed the deterioration of Biden’s mental faculties while in the White House, including in the book “Original Sin: President Biden’s Decline, Its Cover-up, and His Disastrous Choice to Run Again” released May 20. 

“The former first lady should certainly speak up about what she saw in regard to her husband and when she saw it and what she knew, because I think anybody looking again at the videos and photo evidence of Joe Biden with your own eyes and a little bit of common sense can see this was a clear cover up,” Leavitt said. “And Joe, by, Jill Biden was certainly complicit in that cover up.”

“There’s documentation, video evidence of her clearly shielding her husband away from the cameras that were just on ‘The View’ last week,” Leavitt told reporters Thursday. “She was saying, ‘Everything is fine.’ She’s still lying to the American people. She still thinks the American public are so stupid that they’re going to believe her lies. And frankly, it’s insulting and she needs to answer for it.” 

A spokesperson for Jill Biden did not immediately respond to a request for comment from Fox News Digital. 

“Original Sin,” authored by journalists Jake Tapper of CNN and Alex Thompson of Axios, includes stories about how former President Joe Biden struggled to handle fairly routine aspects of a campaign. 

For example, the book says his team attempted to film a campaign video for ads on television in a high school gym, and have people ask questions akin to a town hall meeting.

“The campaign was trying to make it look like the president was out there taking off-the-cuff questions from voters in public,” the book said. “But the event was closed to reporters, and the campaign had the full list of questions that people would ask.”
