GOP senator challenges Teamsters president to fight during hearing

Oklahoma Sen. Markwayne Mullin (R), a former mixed martial arts fighter, nearly came to blows with the president of the Teamsters at a Senate hearing Tuesday, forcing Chair Bernie Sanders (I-Vt.) to step in to stop a brawl from breaking out in the Senate Health, Education, Labor and Pensions Committee room.

Mullin challenged International Brotherhood of Teamsters General President Sean O’Brien to a fight on the spot after the senator read aloud O’Brien’s tweets calling him out as a “clown” and a “fraud.”
