Democratic vice presidential nominee Tim Kaine flatly said on Sunday that Donald Trump has tried to incite violence against Hillary Clinton.

“I do believe that, Chris,” Kaine told Fox News’ Chris Wallace. “I was stunned when I saw it, though he has done that before.”

Kaine’s straightforward remarks were made in reference to comments Trump delivered on Friday night, when he said that Secret Service members protecting Clinton should disarm because of her stance on gun control.

“She doesn’t want guns,” Trump said. “Let’s see what happens to her. Take their guns away, OK, it would be very dangerous.”

Contrary to Trump’s claim, Clinton has no policy on the confiscation of firearms ― nor has she ever called for it ― a point that Kaine made on Sunday. Kaine also noted that this wasn’t the first time that the Republican nominee had hinted (intentionally or not) at a scenario of someone with a gun targeting Clinton.

“He has done it before,” said Kaine, referencing Trump’s suggestion that “Second Amendment people” could stop Clinton from making an appointment to the Supreme Court.

“What did that mean when he said that just three weeks ago?” Kaine asked. “And when you look at a series of these comments that he is making, I do believe it is incitement or at a minimum an expression of indifference to whether violence would occur. And this is a pattern that has been repeated over and over again.”

Following Kaine on Fox News, New Jersey Gov. Chris Christie (R), a Trump surrogate, was downright flabbergasted that Kaine would make such an assertion and demanded an apology. Appearing on ABC’s “This Week,” Trump’s running mate, Mike Pence, called the idea that Trump was inciting violence “absolute nonsense.”

“His comment was that if she didn’t have all that security, she’d change her attitude about the right to keep and bear arms. And I’ll bet that’s probably true. But, you know ... the truth of the matter is ... it really is remarkable,” Pence said.

Editor’s note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims — 1.6 billion members of an entire religion — from entering the U.S.
