President Donald Trump signed executive orders Wednesday targeting former Department of Homeland Security officials Chris Krebs and Miles Taylor, as well as law firm Susman Godfrey. The orders revoked security clearances for the officials who worked under DHS during Trump’s first term.

President Trump has revoked the security clearances belonging to former CISA leader Chris Krebs and ex-DHS official Miles Taylor and ordered investigations into the work they did while in public service.

Trump said Taylor, who spoke out during his first-term administration under the pen-name ‘Anonymous,’ was “like a traitor,” adding: “I think he’s guilty of treason.”
