Hillary Clinton accused Donald Trump of inciting violence when he suggested this week there may be something "Second Amendment people" can do if she wins the White House and appoints pro-gun control judges.

"Words matter, my friends. And if you are running to be president, or you are president of the United States, words can have tremendous consequences," she said Wednesday at a campaign rally in Des Moines, Iowa.

Trump warned supporters Tuesday at an event in North Carolina that, if elected president, Clinton would appoint anti-Second Amendment judges.

"Hillary essentially wants to abolish the Second Amendment," Trump told supporters. "By the way, and if she gets to pick her judges, nothing you can do, folks. Although the Second Amendment people, maybe there is. I don't know."

For Clinton and her team, the GOP nominee's comments were a fairly clear call to action.

"Yesterday, we witnessed the latest in a long line of casual comments from Donald Trump that cross the line. His casual cruelty to a Gold Star family; his casual suggestion that more countries should have nuclear weapons. And now, his casual inciting of violence," the Democratic presidential candidate told supporters.

"Every single one of these incidents shows us that Donald Trump simply does not have the temperament to be president and commander in chief of the United States," she said. "So the stakes have never been higher."

Members of the Secret Service reportedly had multiple conversations with Trump's campaign about his remarks this week on Clinton and the Second Amendment, CNN reported Wednesday.

"US Secret [Service] has spoken to Trump campaign re: 2nd Amendment comments, 'more than one conversation,'" CNN's Jim Sciutto said on social media, citing an anonymous Secret Service source.


However, Trump disputes the story, and claimed on Twitter that no one in his campaign had met with the Secret Service.


Reuters appeared to back up Trump Wednesday afternoon, as the news service reported no formal meeting between the two camps had taken place.

"Secret Service never formally spoke to Trump camp about gun rights comment," Reuters reported, citing an anonymous government official.
