Republicans are investigating whether former President Biden's mental decline was concealed while in office, with calls to subpoena administration members after aide pleads the Fifth.

"As far as I'm concerned, every member of the Biden administration at this point needs to be subpoenaed. I don't care if they were a secretary. I don't care if they were a janitor working in there. They've all got to come in and answer questions," Donalds said.

When asked if that meant the former first lady as well, Donalds responded, "Of course."

He and Comer were both present for the closed-door deposition of Anthony Bernal, a longtime aide to Jill Biden who was subpoenaed in the Oversight Committee's probe.

"Her right-hand man – listen, Anthony Bernal was the right-hand man. That's her guy, her chief of staff," Donalds said. "If he came in here and pleaded the fifth, I'm sorry, the former first lady, she's got to come in here and answer questions."

Comer and Donalds said Bernal argued that invoking the Fifth Amendment was not an admission of guilt, though the GOP lawmakers pushed back on the assertion.

Donalds said it was a "stunning" move.

So far, three Biden aides have been subpoenaed in the investigation. Like Bernal, former White House physician Dr. Kevin O'Connor invoked the Fifth Amendment. Former deputy Chief of Staff Annie Tomascini was also subpoenaed at her lawyer's request.
