Protesters At Obama Rally

So, I am watching Sen. Obama right now give a speech in Florida. Everything is going as planned until about five minutes ago. As I am pouring a bowl of cereal, I hear the crowd getting really loud. I step into the living room to see what is going on and what I see is, well, confusing and interesting. About fifteen African-American men are chanting something and holding up signs. From what I can see, most of the signs have "KKK" in big, bold letters along with some other stuff I don't know. Needless to say, the "KKK" kind of got my attention.
Obama was cool about it. He told the guys that they can hold up their signs if they want but they should let him finish without the noise. I think that's pretty cool. Anyways, they were just escorted out and Obama told the hyped up, protective crowd that it was time to get back to work. Indeed it is.
