Donald Trump on Tuesday warned his supporters that if Hillary Clinton were elected president and appointed members to the Supreme Court, there was nothing anyone could do about it – but then added that, given the Second Amendment, maybe there was.

“If she gets to pick her judges ― nothing you can do, folks,” Trump said at a Wilmington, N.C., rally with a shrug. “Although: the Second Amendment, people, maybe there is. I don’t know.”

What Trump was actually suggesting was not clear. However his veterans affairs adviser found himself in hot water when he said that Clinton should face a firing squad over her use of a private email server.

Trump’s campaign did not respond to queries about his remark, but at least one person attending the rally appeared to sense the comment was out of bounds.

He was, presumably, joking. But joking about assassinating the president or presidential candidates is not taken lightly by the Secret Service, whose agents are tasked with protecting their lives, even at the cost of their own.

In 2010, Nevada Republican Senate candidate Sharon Angle drew criticism for saying in a radio interview that the Second Amendment’s right to bear arms could be used by citizens to take care of what she called an out-of-control Congress, including her opponent, Senate Majority Leader Harry Reid (D-Nev.).

“And you know, I’m hoping that we’re not getting to Second Amendment remedies. I hope the vote will be the cure for the Harry Reid problems,” Angle said.

Angle went on to lose to Reid, despite the Tea Party-fueled Republican wave that year that gave the GOP control of both the House and Senate.
