Donald Trump called former disgraced New York congressman Anthony Weiner a "major, major, major sleaze" on Saturday in discussing the FBI reopening its investigation into Hillary Clinton's emails.

The FBI said Friday that over 1,000 emails found in a separate investigation of Weiner over a sexting scandal he was involved in forced them to revisit Clinton's case.

The FBI said the emails are related to its investigation into Clinton's use of a private server to handle confidential information while she served as Secretary of State. The Bureau did not say what the emails said.

Weiner had shared the emails with his wife, Huma Abedin, who is deputy chair of Clinton's campaign.

"How can you have all this incredible confidential, secret information and have your top person married to this guy?" Trump asked during a rally in Colorado.

"Can we agree that Huma has been a problem?" he asked rhetorically. "I hope they haven't given Huma immunity, because she knows the real story. She knows what's going on."

Trump said he predicted Weiner becoming a problem months ago in a tweet he posted, but "everyone said 'one thing has nothing to do with the other.' Well, turned out its does."
