Bernie Sanders forced to intervene after Republican senator challenges union boss to fight

This is the moment Oklahoma senator Markwayne Mullin stands up and tries to fight labor leader Sean O’Brien during a Senate Help Committee on Tuesday (9 November).

Mullin reads out O’Brien’s tweet from X, formerly Twitter, where O’Brien labels him a “clown and fraud” and says “you know where to find me”.

Mullin then addresses him and says: “This is a time and a place. You wanna run your mouth? We can be two consenting adults. We can finish it here. Do you want to do it now?”

O’Brien replies: “I would love to”

Mullin then stands up and gestures to the labor leader.
