Tennessee Governor Bill Haslam is also criticizing Donald Trump for calling President Obama the founder of ISIS.
The Republican governor says "words matter" when leaders talk about their political opponents. Implying the other side is behind a terrorist organization goes too far, Haslam said.
"It's one thing to go in and say let's look at policy and see what policy drove ISIS to be where it is now, and how has it grown the way it has," he told reporters Friday. "It's another thing, I think maybe to say something like well, the president was the person who started ISIS. That's a pretty grand reach."
Haslam says he won't vote for Hillary Clinton in the general election. But he's still making up his mind about Trump.
