Markwayne Mullin is an American businessman, former professional MMA fighter, and politician who currently serves as a U.S. Senator from Oklahoma. Known for his strong conservative views and outspoken personality, Mullin built his reputation not only in politics but also in business.
Before entering public office, he worked in his family’s plumbing company and eventually turned it into a successful business, which gave him firsthand experience of the challenges faced by small business owners.
Early Life & Educational Details
Markwayne Mullin was born on July 26, 1977, in Tulsa and grew up in the small town of Adair. He was raised in a hardworking family that ran a plumbing business, which played an important role in shaping his work ethic from an early age.
As a teenager, he often helped his father in the family business, learning the value of responsibility and dedication. These early experiences later influenced his approach to business and politics.
For his schooling, he attended Adair High School in Adair, Oklahoma. During his school years, he was actively involved in sports, especially wrestling, which helped him develop discipline and competitiveness.
After graduating from high school, he briefly attended Oklahoma State University Institute of Technology, where he studied subjects related to business and technical training.
However, he did not complete a traditional college degree. Instead, he chose to focus on working full-time in his family’s plumbing company. After his father became ill, Mullin took over the business at a young age and successfully expanded it into a well-known regional company.
This hands-on experience in business later became a key part of his public image, as he often describes himself as a self-made entrepreneur who understands the challenges faced by small business owners.

He is married to Christie Mullin. The couple has been together for many years and built a large and close-knit family. While Christie mostly stays away from public attention, she has supported Mullin throughout his journey from business to national politics.
Markwayne and Christie Mullin are parents to six children: Ivy, Andrew, Larra, Jim, Lynette, and Liam Mullin. Mullin often speaks about how important family is to him and how being a father plays a major role in his life outside politics.
The family lives in Westville, where they maintain strong ties with their local community and continue to value a simple family-oriented lifestyle.
Parents & Family Background
His father, Jim Mullin, owned Mullin Plumbing, a family plumbing business where Markwayne started working at a young age and later took over when his father became ill. His mother, Brenda Mullin, helped raise the family and supported the family business.

MMA & Political Career
Markwayne Mullin has had a diverse career that includes business, sports, and politics, which makes his journey quite different from many traditional politicians.
Business Career:
Before entering politics, Mullin was mainly known as a businessman. He took over his family company, Mullin Plumbing, after his father became seriously ill. Under his leadership, the company grew into one of the largest plumbing service businesses in the region and expanded its operations to multiple states. Besides plumbing services, Mullin also invested in construction, real estate, and other small businesses, which helped him build significant financial success.
MMA Career:
Along with running his business, Mullin also pursued mixed martial arts (MMA) for a short time. Between 2006 and 2007, he competed in professional fights and finished with an undefeated record of 3 wins and 0 losses. Although his MMA career was brief, it highlighted his athletic background and competitive spirit.
Political Career:
Mullin entered politics in 2012 when he ran for Congress as a Republican candidate. He won the election and began serving as the U.S. Representative for Oklahoma’s 2nd congressional district in 2013. He held this position for about ten years (2013–2023) and was re-elected several times.
In 2022, after longtime senator Jim Inhofe announced his retirement, Mullin ran for the U.S. Senate. He won the election and officially became a U.S. Senator from Oklahoma in January 2023.
In 2026, Markwayne Mullin became part of major political news in the United States. U.S. President Donald Trump nominated him to serve as the U.S. Secretary of Homeland Security, which is an important government department responsible for national safety, border protection, and emergency management.
If the nomination receives approval from the Senate, Mullin would leave his current role in the Senate and move into this new leadership position. This possible transition has drawn a lot of attention because it would be a significant step forward in his political career.
As of 2026, Mullin continues to serve as a U.S. senator representing Oklahoma, while the decision about the Homeland Security position remains an important development in his political journey.
