Members of Congress have asked a government watchdog to examine the effect staffing cuts at the Cybersecurity and Infrastructure Security Agency (CISA) have had on the agency’s ability to function.

Bennie Thompson (D-MS), ranking member of the House Committee on Homeland Security, joined several other Democratic representatives in signing a letter asking the Government Accountability Office (GAO) for more information about how CISA is protecting critical infrastructure after nearly one-third of its workforce was slashed at the onset of the Trump administration.
