He more or less said that to a labor union thug as Senator, and was standing up and taking off his jacket to do it. It wasn’t a good career move, the video got featured in his confirmation hearing and he looked like an idiot hothead being proposed for law enforcement leadership, although they ended up pals.
Schoolboy tough guy crap. Use your words.
But it wouldn’t be the first time somebody got beaten badly with a cane in a congressional disagreement.
