Markwayne Mullin is an American politician and businessman who served as the junior United States senator from Oklahoma from 2023 until 2026. A member of the Republican Party, Mullin previously represented Oklahoma's second congressional district in the U.S. House of Representatives from 2013 to 2023. He is also recognized as a member of the Cherokee Nation, making him the first tribal citizen to serve in the U.S. Senate since 2005. Following his Senate tenure, Mullin was appointed as the United States Secretary of Homeland Security in March 2026.
Early life and career
Markwayne Mullin was born on July 26, 1977, in Tulsa, Oklahoma, as the youngest of seven children. He was named after two of his uncles, Mark and Wayne. Raised in Westville, Oklahoma, Mullin has Cherokee heritage through his maternal grandfather, Kenneth Morris. His ancestry includes Native Americans who settled in Oklahoma both before and after the Trail of Tears, a significant event in U.S. history involving the forced relocation of Native American tribes.
During his childhood, Mullin faced health challenges, including a speech impediment and clubfoot, which required him to wear leg braces. Despite these difficulties, he excelled in sports, particularly wrestling, while attending Stilwell High School, from which he graduated in 1996. Mullin received a wrestling scholarship to Missouri Valley College but left in 1998 to manage his family's plumbing business after his father's health began to decline.
Mullin's educational pursuits continued, as he earned an Associate in Applied Science in plumbing from the Oklahoma State University Institute of Technology in 2010. In 2018, he was awarded an honorary doctorate from Bacone College, reflecting his contributions to the community and the field of plumbing.
In 1997, Mullin took over Mullin Plumbing, which had six employees at that time. Under his leadership, the company grew to become Oklahoma's largest plumbing service provider by 2011. Mullin also expanded his business interests, owning multiple companies, including Mullin Environmental, Mullin Services, and Mullin Properties, as well as ranches in Adair and Wagoner Counties. By 2013, he was reported to own eight businesses. In December 2021, Mullin sold his businesses to a private equity firm, although his family continued to operate the plumbing company.
In addition to his business ventures, Mullin briefly pursued a career in mixed martial arts between 2006 and 2007, claiming an undefeated record of 5–0. He was recognized for his achievements in wrestling and was inducted into the National Wrestling Hall of Fame in 2016. Mullin also operated a jujutsu and mixed martial arts school in Broken Arrow, Oklahoma, by 2012.
Mullin ventured into media by hosting a call-in radio program called House Talk, which focused on home improvement topics. The program was syndicated on Saturday mornings on KFAQ and was noted for its engaging format, similar to NPR's Car Talk.
Senate tenure
Mullin's political career began in earnest when he ran for the U.S. House of Representatives in 2012, following the announcement by incumbent Dan Boren that he would not seek reelection. Mullin established a campaign committee and loaned his campaign $100,000, expressing his opposition to certain provisions of the Affordable Care Act. He successfully won the election in 2012, defeating Democratic candidate Rob Wallace, and was subsequently reelected multiple times.
In February 2022, U.S. Senator Jim Inhofe announced his intention to resign at the end of the 117th Congress. Mullin entered the special election to succeed Inhofe, winning the Republican primary and the subsequent runoff against state House Speaker T.W. Shannon. He then defeated Democratic nominee Kendra Horn in the general election, officially taking office as a U.S. senator in 2023.
During his time in the Senate, Mullin became known for his focus on issues pertinent to his constituents and the broader national landscape. His election marked a significant moment in U.S. history, as he became the first tribal citizen to serve in the Senate since Ben Nighthorse Campbell's retirement in 2005. Mullin's tenure in the Senate lasted until March 2026, when he was nominated by President Donald Trump to serve as Secretary of Homeland Security.
Legislative focus and committees
Throughout his congressional career, Mullin's legislative focus encompassed a range of issues, particularly those affecting his home state of Oklahoma and the interests of Native American communities. His experience as a businessman informed his approach to economic and regulatory matters, where he often advocated for policies aimed at promoting business growth and reducing government intervention.
In the House of Representatives, Mullin served on various committees, contributing to discussions and decisions on legislation that impacted his constituents. His background in plumbing and business provided him with unique insights into infrastructure and economic development issues, which he prioritized during his time in office.
As a senator, Mullin continued to engage with issues relevant to his constituents, including economic development, public safety, and tribal affairs. His role in the Senate allowed him to advocate for policies that aligned with the interests of the Cherokee Nation and other Native American communities.
Mullin's transition to the role of Secretary of Homeland Security in March 2026 marked a new chapter in his public service career. His appointment to the Cabinet underscored the significance of his representation as a member of the Cherokee Nation, furthering the visibility of Native American leaders in high-level government positions.
Overall, Markwayne Mullin's career reflects a blend of business acumen and public service, with a focus on the needs of his constituents and the broader implications of policy decisions at the federal level. His journey from a local businessman to a U.S. senator and ultimately to a Cabinet member illustrates the diverse pathways individuals can take in American politics.
