Sen. Susan Collins, R-Maine, won't vote for Donald Trump, but she thinks the GOP nominee is being unfairly accused of calling for violence against Democratic presidential nominee Hillary Clinton.

"I think that he was suggesting that the Second Amendment advocates across the country might be able to come together to pressure the Senate to reject her nominees, should she become president," Collins said on "Meet the Press Daily." "That's how I interpreted it."

Trump started a new controversy during a Tuesday stump speech, when he warned supporters that Clinton "wants to abolish the Second Amendment" if she wins the presidency. "By the way, and if she gets to pick her judges, nothing you can do, folks," Trump said. "Although the Second Amendment people, maybe there is."

Clinton's campaign manager condemned the remark as "dangerous" and some of her allies called for a Secret Service investigation. "Don't treat this as a political misstep," Sen. Chris Murphy, D-Conn., tweeted. "It's an assassination threat, seriously upping the possibility of a national tragedy & crisis."

Collins, who announced Monday night that she will not vote for Trump in the fall election, nevertheless rejected such reactions. "I've been very critical of Donald Trump but I actually don't think that's what he was saying," she said. "But it is an example of Donald Trump's looseness with language that can lead to interpretations that, such as the one put out by Secretary Clinton's camp."
