Seems he was a "Truther".
Here. If I were to try and place blame on anyone other than Loughner, like so many on the Left are, then I could say that Van Jones was to blame. He is a Truther as well. The fact is however, than Loughner, and only Loughner, is to blame for his actions.
The more that comes out about this guy, the more those on the Left, who are trying to use this story as a political weapon against the Tea Party, are going to look almost as crazy as Loughner.
