The Secret Service is under pressure Wednesday to investigate Donald Trump after the Republican presidential candidate made comments that were widely interpreted as an incitement of violence against his Democratic opponent, Hillary Clinton. Thousands of people took to Twitter and admonished the protection service which is charged with the security of both candidates, calling on them to investigate and arrest Trump.

Speaking at a rally in North Carolina Trump said if Clinton won, she would appoint judges who would institute stricter gun control laws. “If she gets to pick her judges, nothing you can do, folks,” Trump told a rowdy audience. “Although the Second Amendment people — maybe there is, I don’t know.”

The remarks caused an uproar and online, tens of thousands of people urged the Secret Service to investigate Trump, and even arrest him, for threatening the life of a presidential candidate.

Vocativ found that the first comments tagging the Secret Service began at 3:13 pm Eastern Time, moments after the news broke about Trump’s remarks.

A further 7,264 posts were published tagging the Secret Service, many of them demanding action, until the Secret Service’s official Twitter account responded with a comment at 6:39 pm, saying they “were aware” of comments made during the afternoon.

Trump later dismissed the outrage and claimed his comments were misinterpreted. He said he was referring to the rights of voters to change outcomes. “There can be no other interpretation,” he told Fox News. His campaign also released a statement clarifying the remarks: “It’s called the power of unification – 2nd Amendment people have amazing spirit and are tremendously unified, which gives them great political power.”
