Anita Dunn is a longtime Democratic operative who is appearing before the House Oversight Committee on Thursday.

Anita Dunn, former aide to President Joe Biden, is expected to testify in front of the House Oversight Committee on Thursday over allegations of a cover-up involving Biden’s mental fitness and use of an autopen.

Like other former Biden administration officials, Dunn will face questions about the former president’s mental acuity and autopen use during his term.
