Sara, I agree that they should have stated their names however, as you say, the congressman's response - a physical assault - was in NO WAY justified. I have no idea if it was a set up but it really doesn't make any difference. The congressman revealed his character. The young men were polite, even calling him 'sir'. Their question was perfectly reasonable and they have a right to ask it -- it's not a question of minding your own business. The congressman is an elected official. His business, in this case where he stands on political matters, is the nation's business. It's very common for reporters or even regular citizens to stop politicians on the street and ask questions. What we see on the video looks like what you'd expect in a police state.
