Rep. Bennie Thompson

Mississippi Democrat Bennie Thompson chairs the House Homeland Security Committee and will also help investigate the Capitol attack. Thompson previously filed a suit against Trump, Rudy Giuliani, as well as two “right-wing extremist groups” for  “damages for the emotional distress he suffered during the Jan. 6 mob attack on the Capitol,” and alleges that Trump “acted beyond the outer perimeter of his official duties” in directing the mob “and therefore is susceptible to suit in his personal capacity.”
