It was depressing to hear that John McCain is once again facing phony accusations and slanderous whispers as he campaigns in South Carolina.

I don't support any candidate, so I am not saying this because of any particular affinity for Sen. McCain. I am saying this because more than ever we need to be brought together as a country, as a citizenry, and these kind of tactics are all about creating divisions.
This happened to Sen. McCain back in 2000, and now at least he has the money and experience to aggressively challenge these false rumors and aggressive automated calls which spread untruths, but some people will no doubt believe them.
Tonight, we take an up close look at some of the dirty tricks being used so far in this election season, and Joe Johns has a one-on-one interview with Sen. McCain.
We'll also be looking at the latest on the murder of Maria
Lauterbach, and we'll take an up close look at Scientology. See you at 10p ET!
