Sen. Markwayne Mullin (R-OK) on Monday challenged Teamsters President Sean O’Brien to a physical fight in response to some tweets calling the senator a “clown and fraud,” the HuffPost reports.
Tweeted Mullin: “An attention-seeking union Teamster boss is trying to be punchy after our Senate hearing. Okay, I accept your challenge. MMA fight for charity of our choice. Sept 30th in Tulsa, Oklahoma. I’ll give you 3 days to accept.”
