❓WHAT HAPPENED: President Donald J. Trump announced a change in the position of United States Secretary of Homeland Security, effectively firing Kristi Noem via Truth Social.
👤WHO WAS INVOLVED: Kristi Noem, Markwayne Mullin, and Donald Trump.
📍WHEN & WHERE: The announcement was made via Truth Social, effective March 5, 2026.
đź’¬KEY QUOTE: “Markwayne will make a spectacular Secretary of Homeland Security.” – Donald Trump
🎯IMPACT: Markwayne Mullin will take over as Secretary of Homeland Security, while Kristi Noem transitions to a new role as Special Envoy for The Shield of the Americas.
President Donald J. Trump announced a significant leadership change in his administration. Markwayne Mullin, a United States Senator from Oklahoma, is set to become the new Secretary of Homeland Security, effective March 31, 2026.
The news comes after Kristi Noem, who will move into a new role as Special Envoy for The Shield of the Americas, became embroiled in a $220 million ad-buying campaign scandal, covered here by The National Pulse.
Trump praised Noem for her service, particularly her accomplishments on border security. He expressed gratitude for her contributions, stating, “I thank Kristi for her service at ‘Homeland.'”
Markwayne Mullin, who served 10 years in the House of Representatives and three in the Senate, has been recognized as a “MAGA Warrior.” Trump emphasized Mullin’s dedication to advancing the America First agenda and his commitment to securing the border.
When Sen. Markwayne Mullin joins President Trump’s cabinet, Oklahoma Gov. Kevin Stitt will appoint a temporary replacement within 30 days.
The appointee must be a Republican who has been a registered Oklahoma voter in that party for at least the previous five years, and they must sign a written promise not to run for the seat in the upcoming election. This interim senator would serve until the winner of the regular November 2026 Senate election is sworn in early 2027. Since Mullin’s seat is already scheduled for the 2026 ballot (where he had been seeking his first full six-year term), no separate special election is needed.
