CNN host Jake Tapper has co-authored a book alleging that figures within the Democratic Party helped to cover up former President Joe Biden's decline.

One of those figures is former first lady Jill Biden, and White House press secretary Karoline Leavitt recently pointed to what she says is evidence of that guilt.

Leavitt lets loose

"I think, frankly, the former first lady should certainly speak up about what she saw in regards to her husband and when she saw it and what she knew," the Daily Wire quoted Leavitt as telling reporters on Thursday.

"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. Jill Biden was certainly complicit in that cover-up," she asserted.

"There’s documentation, video evidence of her clearly shielding her husband away from the cameras. They were just on 'The View' last week. She was saying everything is fine," Leavitt stressed.

"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," the press secretary went on to complain.

Hur audio raises eyebrows

Leavitt is not the only Trump administration official to take aim at the former first lady, as a senior Department of Justice official has done so as well.

Leo Terrell serves as a counselor to the assistant attorney general for civil rights, and Breitbart reported that he put out a social media post earlier this month which accused Mrs. Biden of committing "elder abuse."

Terrell's comment came not long after Axios publicized an audio recording of the 2023 interview of then-President Biden conducted by then-special counsel Robert Hur.

Exclusive: Axios obtained the audio of Robert Hur's 2023 interviews of Biden which show repeated mental lapses as he struggles to remember words & dates amid long, uncomfortable pauses.

"Well…. I, I, I, I, I, I don’t know. This is what -- 2017, 2018, that area?" a fragile-sounding Biden could be heard saying when Hurr asked him about his handling of classified documents.

Biden's poor memory laid bare

"Remember, in this time frame, my son is either been deployed or is dying," Joe Biden said of his son, Beau Biden, who died of cancer in 2015.

"And, so, it was, and by the way, there are still a lot of people at the time when I got out of the Senate that were encouraging me to run in this period, except the president," the then president remarked, even though he left the Senate in 2009.

Later in their conversation, Biden seemed to be confused about which year former Secretary of State Hillary Clinton ran for the presidency, providing additional fodder for the scrutiny that continues to mount.
