Charles Krauthammer told viewers Thursday on “Special Report with Bret Baier” that FBI director James Comey decided not to prosecute Hillary Clinton because he “didn't want to be remembered as the guy who changed the course of American political history.” 

"She would have been out of the race. The entire campaign would have been upended," the syndicated columnist said. "And to me, it's a bit like and I’ve spoken about this before, Chief Justice Roberts in deciding on Obamacare."

Krauthammer believed Comey was looking for a way to "avoid" indicting Clinton because it "would have changed the course of American political history."
