Noem, 54, will likely be at least temporarily replaced by Deputy Secretary Troy Edgar, a Navy veteran and former mayor of Los Alamitos, California, in the line of succession for the agency.
House before Trump officially fired Noem, Punchbowl News reported Trump had privately asked Republican lawmakers whether he should fire Noem following a series of bruising congressional hearings this week.
The conversations reportedly took place after Noem testified before the Senate and House Judiciary Committees, where she faced pointed questioning over the administration’s immigration crackdown and a controversial government-funded advertising campaign tied to the Department of Homeland Security.
Trump was said to be particularly irritated by Noem’s exchange with Senator John Kennedy (R-La.). During the hearing, Kennedy pressed the DHS secretary on whether the president had personally approved a $220 million advertising campaign that prominently featured Noem. President Donald Trump has reportedly floated Senator Mullin as a possible replacement for Noem.
Kennedy repeatedly asked whether Trump had signed off on the effort and warned that the situation could politically backfire on the president. He cautioned that the campaign risked putting Trump “in a terribly awkward spot.”
The Louisiana Republican also questioned why the advertising contract was awarded to a firm run by the husband of Noem’s former DHS spokesperson, Tricia McLaughlin, raising concerns about potential conflicts of interest.
