During brief remarks to reporters during a New Year’s Eve celebration at his Mar-a-Lago resort in Palm Beach, Fla., Trump repeated his skepticism of U.S. intelligence agencies’ assertions that Russia was behind the hacking.

“I just want them to be sure because it’s a pretty serious charge,” Trump said. “If you look at the weapons of mass destruction, that was a disaster, and they were wrong.”

“So I want them to be sure,” he added. “I think it’s unfair if they don’t know.”

Trump also said he knows “a lot” about hacking, saying it is a “very hard thing to prove.”
