Hillary Clinton told CNN that she believes the shooting tragedy in Tucson, Arizona was motivated from "political extremism." "Based on what I know, this is a criminal defendant who was in some ways motivated by his own political views, who had a particular animus toward the congresswoman, and I think when you cross the line from expressing opinions that are of conflicting differences in our political environment into taking action - violent action- that's a hallmark of extremism. Whether it comes from the right, the left, Al Qaeda, from anarchists, whoever it is."
