In an apparent reference to a report that the Secret Service had been in contact with the Donald Trump campaign over his comment Tuesday that “Second amendment people” would put a stop to Hillary Clinton, Trump tweeted Wednesday that he had no such “conversation” while blaming “low ratings” CNN for making up the story.

At a rally Tuesday, Trump said that if Clinton is elected and allowed to pick anti-gun rights judges, there’s “nothing you can do, folks.”

“Although the Second Amendment people, maybe there is,” Trump continued, in a remark interpreted by many to be a reference to assassinating Clinton. The Trump campaign disputes that interpretation.

A CNN reporter tweeted Wednesday that a Secret Service official told him that “more than one conversation” had been had between the agency and the Trump campaign over the remark.

Reuters later reported that a government official told the outlet the Secret Service never “formally” spoke to Trump’s campaign about the comment.
