Relatives of a U.S. Capitol Police officer who died by suicide following the Jan. 6 Capitol insurrection said they support a commission to investigate the days events.

U.S. Capitol Police Officer Howie Liebengood, a 15-year police veteran, was one of two officers who died by suicide days after the deadly attack on the Capitol that left several dead and 140 officers injured . Liebengoods death was a direct result of the trauma and strain from the January 6th attack on the Capitol and the around-the-clock shifts in the subsequent days, his family said.

A Democrat-backed measure in the House to form a 9/11-style commission about the insurrection is set to be approved Wednesday, though Senate Republicans have suggested they will try to block efforts for a bipartisan investigation into the attack.
