Sen. Elizabeth Warren (D-MA) labeled Donald Trump’s remarks about “Second Amendment people” stopping Hillary Clinton a “death threat” and said Trump was a “pathetic coward who can’t handle the fact that he’s losing to a girl.”

Trump at a rally Tuesday warned against what would happen if Clinton was elected and allowed to pick Supreme Court judges.

“If she gets to pick her judges,” Trump said, “nothing you can do, folks. Although the Second Amendment people, maybe there is.”

His campaign later said he was referring to the political power of Second Amendment supporters.
