Top Biden officials summoned to testify about alleged cover-up of former president's mental fitness

Former Domestic Policy Council Director Neera Tanden will meet with the committee on Tuesday, and former Assistant to the President and Senior Advisor to the First Lady Anthony Bernthal will meet with the committee on Thursday. 

The committee also has interviews scheduled with former administration officials Annie Tomasini and Ashley Williams, while seeking interviews with several officials in the Biden inner circle, including former Chief of Staff Ron Klain and former Senior Advisor to the President for Communications Anita Dunn. 

Biden's former doctor, Kevin O'Connor, will sit down with House investigators in July.

Among the questions House investigators are expected to have is whether any Biden officials used the autopen to authorize executive actions without the president's permission. 

The sit-downs are behind closed doors, as opposed to public congressional hearings.

The interviews will be transcribed and likely released at a later date.

Comer previously told Fox News Digital that the more muted setting of a closed-door interview would allow House lawmakers to get more key information, as opposed to the public spectacle of a hearing.

"I've studied history, there's never been a committee hearing that did what it's supposed to do," Comer said.

"But these depositions and interviews, do. You've got one hour, you're not interrupted, you don't have to go five minutes back and forth. So to extract information, we're going to go with the interviews. We could have a hearing later on, but right now, I think we can get more done quicker with interviews."
