President Donald J. Trump has replaced Kristi Noem with Oklahoma Sen. Markwayne Mullin as the next U.S. Secretary of Homeland Security. Trump made the announcement on Truth Social Thursday afternoon.

“I am pleased to announce that the Highly Respected United States Senator from the Great State of Oklahoma, Markwayne Mullin, will become the United States Secretary of Homeland Security (DHS), effective March 31, 2026,” Trump wrote. “Markwayne will make a spectacular Secretary of Homeland Security.”

If confirmed by the Senate, Mullin, a Cherokee Nation citizen, will be the second Native American man to be in the president’s cabinet, the first Native person to be Homeland Security secretary, and the second Native person to run an agency. He follows the footsteps of previous Native Americans in the presidential cabinet: former Vice President Charles Curtis, Kaw Nation, and former U.S. Secretary of Interior Deb Haaland, Laguna Pueblo.

Curtis served as vice president under former President Herber Hoover. At that time, the vice president post was also part of the presidential cabinet. Haaland served under the Biden administration for four years. Mullin became the first Native American man to serve in the U.S. Senate since the late Ben Knighthorse Campbell, who served as Colorado’s senator from 1993 to 2005.

 

PRESIDENT DONALD J. TRUMP

 

I am pleased to announce that the Highly Respected United States Senator from the Great State of Oklahoma, Markwayne Mullin, will become the United States Secretary of Homeland Security (DHS), effective March 31, 2026. The current Secretary, Kristi Noem, who has served us well, and has had numerous and spectacular results (especially on the Border!), will be moving to be Special Envoy for The Shield of the Americas, our new Security Initiative in the Western Hemisphere we are announcing on Saturday in Doral, Florida. I thank Kristi for her service at “Homeland.”

Serving 10 years in the United States House of Representatives, and 3 in the Senate, Markwayne has done a tremendous job representing the wonderful People of Oklahoma, where I won all 77 out of 77 Counties — in 2016, 2020, and 2024! A MAGA Warrior, and former undefeated professional MMA fighter, Markwayne truly gets along well with people, and knows the Wisdom and Courage required to Advance our America First Agenda. As the only Native American in the Senate, Markwayne is a fantastic advocate for our incredible Tribal Communities. Markwayne will work tirelessly to Keep our Border Secure, Stop Migrant Crime, Murderers, and other Criminals from illegally entering our Country, End the Scourge of Illegal Drugs and, MAKE AMERICA SAFE AGAIN. Markwayne will make a spectacular Secretary of Homeland Security. Thank you for your attention to this matter!

PRESIDENT DONALD J. TRUMP
