Comer subpoenas another former Biden aide in probe of autopen use, mental fitness

House Oversight Chair James Comer issued another subpoena to a former Joe Biden aide in an effort to compel testimony as part of his investigation into the former president’s use of the autopen and mental fitness while in office.

The Kentucky Republican sent the letter to Annie Tomasini, Biden’s former White House deputy chief of staff, who is scheduled to sit down with investigators on Friday. The committee said her legal team had informed them she requested a subpoena to appear, although she had originally agreed to speak voluntarily.

Comer has also subpoenaed Biden’s former White House physician Kevin O’Connor, who cited his 5th Amendment right and doctor-patient confidentiality in declining to cooperate.

On Wednesday, the panel is scheduled to interview Anthony Bernal, a top aide to the former First Lady Jill Biden, who was also subpoenaed.
