Rep. Steve King (R-IA) stood outside the Supreme Court on Monday and faced down an angry mob of immigrant activists who were shouting him down during his remarks. He asked them directly if this is the kind of behavior we can expect of people trying to become American citizens.

Not only did he reprimand them for their rudeness, he also reminded them they have a constitutional obligation to peaceably assemble rather than shout down every word. Here is what he told the loud crowd, who didn't hear what they needed to:

Why are you all yelling? You want to be citizens of America and conduct yourselves in a fashion where you try to shout down someone who is exercising their right to freedom of speech? Do I need to start reading the Constitution from the First Amendment? Freedom of speech and religion and the press and peaceably assemble; it's not peaceable to try to shout people down. You're supposed to be demonstrating what good citizens you would make rather than the kind of actions you have here.

So, is this behavior out here in the streets of America that we see today that disrespects this court, disrespects the Congress of the United States, disrespects this congressman who serves on the Constitution subcommittee and the full House Judiciary Committee; Are you an example of the America we can expect if this court finds that the president can write law and violate the Constitution at will? If so, we're in for a rough ride in the future.
