WASHINGTON, DC – SEPTEMBER 17: House Homeland Security Committee member Rep. Elissa Slotkin (D-MI) questions witnesses during a hearing on ‘worldwide threats to the homeland’ in the Rayburn House Office Building on Capitol Hill September 17, 2020 in Washington, DC. Committee Chairman Bennie Thompson (D-MS) said he would issue a subpoena for acting Homeland Security Secretary Chad Wolf after he did not show for the hearing. An August Government Accountability Office report found that Wolf’s appointment by the Trump Administration, which has regularly skirted the Senate confirmation process, was invalid and a violation of the Federal Vacancies Reform Act.
