Rumble in the Senate: Senator challenges union boss to fight mid-committee hearing

Here is the clip of the senator trying to start a fight during a committee hearing with a union boss. Markwayne Mullin, a senator from Oklahoma, read out a tweet from Sean O'Brien's, a union boss, in which he challenges the senator to a physical fight, "any time, any place". Mullin then challenges him to a fight in the committee chamber: "You want to do it right now? Stand your butt up then." The fight is then broken up by Bernie Sanders, chair of the committee: "You are a United States senator -- sit down." #senate #politics #usa Subscribe to The Telegraph with our special offer: just £1 for 3 months.
