Oklahoma Senator Markwayne Mullin, a former MMA fighter, has been appointed as the next US Secretary of Homeland Security. In a shocking moment from 2023, Mullin challenged Teamsters president Sean O'Brien to a fight after the union leader made derogatory comments about him.
During a Senate hearing, Mullin confronted O'Brien over his posts on X, calling him a 'clown' and a 'fraud.' O'Brien responded, 'You know where to find me. Anyplace, Anytime cowboy.'
Mullin then directly challenged O'Brien, saying, 'Sir, this is a time. This is a place. You want to run your mouth? We can be two consenting adults, we can finish it here.'
O'Brien accepted the challenge, and Mullin proposed an MMA fight for charity on September 30th in Tulsa, Oklahoma. He gave O'Brien three days to accept the challenge.
