The chairman has also requested a transcribed interview with Biden’s physician, Dr. Kevin O’Connor.
Comer told Fox News last week that these "unelected bureaucrats" had an overwhelming influence over Biden and were possibly serving as "de facto" presidents in his stead.
"Today, we are calling on President Biden’s physician and former White House advisors to participate in transcribed interviews so we can begin to uncover the truth," Comer said in a statement.
The GOP effort comes shortly after the release of "Original Sin" by CNN host Jake Tapper and Axios reporter Alex Thompson, which claims that the Biden White House was going all out trying to control the perception of the aging president’s failing health. The book exposes the cover-up of Biden's decline and his decision to run for re-election.
Tapper said during an interview with Piers Morgan on Monday that what Biden's aides did to hide his condition from the public could be "even worse" than the Watergate scandal during Richard Nixon's presidency.
"It is a scandal. It is without question, and maybe even worse than Watergate in some ways," said Tapper. "The only reason we invoke Watergate is just to make clear like, it's not Watergate — this is an entirely separate scandal, maybe even worse."

On Tuesday, Comer floated the possibility of also issuing subpoenas to former White House press secretary Karine Jean-Pierre as well as Hunter Biden and Jill Biden.
"Obviously, we're interested in Jean Pierre. … We're also interested in Jill Biden and Hunter Biden," he said, adding that "if the trail leads us to the next step, which many believe would be perhaps Jill Biden and Hunter Biden, then we will go there."
Fox News Digital reached out to Tanden, Tomasini, Bernal, Williams, O’Connor and Jean-Pierre for comment.
