Former Trump White House trade adviser Peter Navarro was convicted last year for defying a subpoena from the House committee investigating the Jan. 6 Capitol attack.

Former President Donald Trump has repeatedly invoked executive privilege as attempts to block testimony about the Jan. 6 attack on the U.S. Capitol.

Mark Meadows is suing House Speaker Nancy Pelosi and the House Jan. 6 committee, asking a judge to block enforcement of two subpoenas it had issued for himself and Verizon.

The department says it would not be appropriate for former officials to claim executive privilege forbids them from testifying before Congress.
