And he has an army of union goons who are more than willing to resort to violence.

(CNN)Jimmy Hoffa, president of the International Brotherhood of Teamsters, said Tuesday he expects Michigan unions and lawmakers to break out into “civil war” after the state legislature passed right-to-work bills that would weaken unions’ power.

“This is just the first round of a battle that’s going to divide this state. We’re going to have a civil war,” Hoffa said on CNN’s “Newsroom.

As thousands of protestors gathered at the state capitol on Tuesday, Hoffa called the legislation a “tremendous mistake” and “a monumental decision to make” by outgoing lawmakers in a lame duck session.

“What they’re doing is basically betraying democracy,” he told CNN’s Brooke Baldwin. “If there’s any question here, let’s put it on the ballot and let the people of Michigan decide what’s good for Michigan.”
