President shifts Noem to Western Hemisphere security envoy role as internal frustrations over DHS leadership grow inside the administration.
WASHINGTON | President Donald Trump announced Thursday that he intends to nominate Markwayne Mullin to serve as the next Secretary of the United States Department of Homeland Security, replacing current department chief Kristi Noem, who will transition to a new diplomatic security role focused on the Western Hemisphere.
The announcement, made on Trump’s Truth Social platform, signals a significant leadership shakeup at the federal agency responsible for border security, immigration enforcement, and domestic counterterrorism operations.
Trump said Noem would take on a new assignment as special envoy for a regional security initiative aimed at strengthening cooperation with Latin American partners.
“Kristi has served us well, and has had numerous and spectacular results — especially on the Border,” Trump wrote. “She will now lead our new Security Initiative in the Western Hemisphere.”
The president said further details about the initiative will be unveiled during a summit with Latin American leaders scheduled for Saturday in Florida.
