New revelations that the FBI is investigating additional emails in the Hillary Clinton case may prove Donald Trump right in his claim over a year ago that notorious sexter Anthony Weiner was a threat to national security.

Director James Comey sent a letter to Congress on Friday announcing that the FBI was reopening the investigation after obtaining new emails relevant to Hillary Clinton's emails "in connection with an unrelated case."

"I agreed that the FBI should take appropriate investigative steps designed to allow investigators to review these emails to determine whether they contain classified information, as well as to assess their importance to our investigation," Comey said.

The New York Times reported the emails were recovered after the FBI seized electronic devices belonging to Clinton's close aide Huma Abedin and her husband, Anthony Weiner. Wiener is under federal investigation for sexting a minor, after the Daily Mail's Alana Goodman revealed his salacious texts with a 15-year-old girl.

The report followed the New York Post exclusive that Weiner was sexting with his toddler son next to him, which prompted Abedin to announce she was separating from her husband.

After the separation was announced, Trump, who has long called Weiner a "pervert," said Weiner's proximity to one of Hillary Clinton's closest aides was a threat to national security.

"Huma is making a very wise decision," Trump said in a statement in August. "I know Anthony Weiner well, and she will be far better off without him. I only worry for the country in that Hillary Clinton was careless and negligent in allowing Weiner to have such close proximity to highly classified information."

"Who knows what he learned and who he told?" he said. "It’s just another example of Hillary Clinton’s bad judgment. It is possible that our country and its security have been greatly compromised by this."

Trump said Weiner was a security risk as far back as August 2015.
