BRIAN KILMEADE (CO-HOST): Keep in mind, when Donald Trump brings this up, this is not new. When the communist threat was the number one threat, we did have an Alien and Sedition Act that dated back to 1798, when we were worried about going to war with France. We wanted to make sure people here weren't against us. In the 1950s, the McClaren Act -- the McCarran Act, I should say, addressed the red scare here. So, if you're a communist, we need you to register because we've got to keep an eye on you, and because that was the number one threat at that time, as is Islamic extremists today.
