Markwayne Mullin is the 9th Secretary of the Department of Homeland Security.

Prior to serving in President Trump’s Cabinet, Secretary Mullin represented the people of Oklahoma for 13 years in both the United States Senate and House of Representatives.

During his time in the U.S. Senate, Markwayne Mullin quickly earned a reputation as a lead nexus policymaker among the Republican-led House, Senate, and White House in support of President Trump’s legislative agenda. Mullin is known as a strong ally of the President while also striving to find common ground across the aisle on behalf of the American people. Last year, Mullin championed the fight to get major legislation, including the ‘One Big, Beautiful Bill,’ the National Defense Authorization Act, the Give Kids a Chance Act, and President Trump’s 12 appropriations bills across the finish line.

He is a successful business owner, working cow-calf rancher, and proud husband of 28 years to Mrs. Christie Mullin, and together the two are parents to six wonderful children: Jayce, Jim, Andrew, Larra, Ivy, and Lynette.

A lifelong Oklahoman, Senator Mullin grew up on his family’s ranch in Westville where he and his family still reside to this day. A graduate of Stilwell High School, Mullin went on to attend Missouri Valley College on a wrestling scholarship until the age of 20 years old. At that time, Senator Mullin’s father, Jim, fell ill, and Mullin and his recent bride Christie postponed studies to take over the family business, Mullin Plumbing.

Over the past 25 years, Markwayne and Christie Mullin have expanded Mullin Plumbing to become the largest service company in the region, and along the way founded numerous other successful companies.
Senator Mullin is an enrolled member of Cherokee Nation and he was the second Cherokee Nation citizen to ever serve in the U.S. Senate. He is now the second Tribal citizen to serve in the President’s Cabinet.

Markwayne Mullin is a former undefeated Mixed Martial Arts (MMA) fighter with a professional record of 5-0. He was inducted into the Oklahoma Wrestling Hall of Fame in 2016. Mullin has remained active in the wrestling community since his retirement from the sport, continuing to coach his children and other young athletes in wrestling tournaments across the country on weekends through today.
