Donald Trump has dismissed Kristi Noem as homeland security secretary, replacing her with Republican Senator Markwayne Mullin after weeks of bipartisan criticism over her leadership. The move follows the killing of two US citizens by immigration agents and reports of a personal relationship between Noem and a top deputy.
Trump announced the change on Truth Social, praising Noem’s service but stating Mullin would take over from 31 March. Noem will become special envoy for the “Shield of the Americas” initiative, which Trump plans to unveil shortly. Mullin described the appointment as “humbling” and said he had to call his father after the sudden news.
Democrats welcomed Noem’s departure. House minority leader Hakeem Jeffries said: “Good riddance. She was a disaster.” However, he stressed that a change in personnel does not address the need for policy reforms. Senate Democrat Chuck Schumer added that he does not trust anyone leading the agency under Trump, citing deep-rooted issues.
Republican Senator Lindsey Graham acknowledged Noem’s service but agreed “it was time for a change.” Noem, a former South Dakota governor, had been considered a potential running mate for Trump in 2024 but was passed over after admitting to killing her dog. She became the public face of the immigration crackdown, which drew controversy after ICE agents killed Renee Good and Alex Pretti, both US citizens.
Noem accused the victims of “domestic terrorism,” a claim disputed by their families and Democrats. Reports also emerged of turmoil within the department, including Noem’s relationship with adviser Corey Lewandowski and the use of polygraph tests on staff. Despite the firing, the Department of Homeland Security remains partially shut down due to a Senate funding dispute.
