In a surprise move Thursday, President Donald Trump announced that Kristi Noem is out as Secretary of Homeland Security, with Oklahoma Senator Markwayne Mullin stepping in to fill the role. The announcement, made on Trump’s Truth Social platform, said Mullin would officially take over leadership of the Department of Homeland Security (DHS) on March 31, pending Senate confirmation.
Noem’s Tumultuous Tenure Ends
Trump publicly thanked Noem for her work, commending her for “numerous and spectacular results,” especially on border enforcement. Still, reports suggest the president’s patience wore thin after Noem’s recent Senate testimony, which revealed that Trump had personally approved a $220 million DHS ad campaign featuring Noem herself. The campaign, urging undocumented migrants to leave the US voluntarily, drew bipartisan criticism for both its cost and effectiveness.
During the hearing, Democrats blasted the department’s immigration policies, with Senator Dick Durbin accusing DHS under Noem of lacking a “moral compass.” Republican lawmakers also voiced frustration: Senator Thom Tillis labeled her leadership a “disaster,” citing cases where US citizens were mistakenly detained, while Senator John Kennedy questioned whether the ad campaign did little more than raise Noem’s profile.
New Role for Noem as Mullin Steps Up
Although she’s leaving the cabinet, Noem won’t be exiting the administration entirely. Trump announced she will serve as his special envoy for a new initiative called “The Shield of the Americas,” designed to boost regional security throughout the Western Hemisphere.
Markwayne Mullin, described by Trump as a “MAGA warrior,” faces Senate confirmation, but with Republicans holding the majority, his prospects appear strong. Trump expressed confidence that Mullin would “work tirelessly to keep our border secure, stop migrant crime, and end the scourge of illegal drugs entering our country.”
DHS at a Crossroads
Noem’s departure comes as the DHS faces a partial shutdown due to ongoing conflicts over immigration policy. The department remains central to Trump’s agenda, especially as the administration pushes forward with plans for large-scale deportations of undocumented immigrants. All eyes now turn to Mullin as he prepares to steer the agency through turbulent times.
