Priorities USA, a super PAC that has endorsed Hillary Clinton, is running a TV advertisement in several states in an effort to undermine Donald Trump on foreign policy.

The ad is running in states crucial to the general election, including Ohio, Florida and Nevada. It uses audio clips of Trump's past statements on foreign policy matters.

"I'm really good at war," he says in one clip. "I love war, in a certain way."

The ad closes with text that says, "Donald Trump: Too dangerous for America."
