On the "Today" show on Thursday, Donald Trump said that despite the fact that he found nuclear weapons to be abhorrent, he wouldn't rule out using them against ISIS.

“I don’t want to rule out anything,” he said Thursday on NBC’s “Today.” Trump noted he doesn't want to use nuclear weapons, calling them "a horror."

“The power of weaponry today is the single greatest problem that our world has, and it’s not global warming like our president said, it’s the power of weapons — in particular, nuclear," he said.

“I will be the last to use it. I will not be a happy trigger like some people might be, but I will never, ever rule it out.”
