"And so I want them to be sure. I think it's unfair if they don't know," he added. "And I know a lot about hacking. And hacking is a very hard thing to prove. So it could be somebody else. And I also know things that other people don't know, and so they cannot be sure of the situation."
Arriving at his New Year's bash Saturday at Mar-a-Lago, in Palm Beach, Florida, Trump also doubled down on cyber security claims that computers are partially to blame, telling reporters that no computer is safe from hacking and secure messages should instead be sent via courier.
"It's very important, if you have something really important, write it out and have it delivered by courier, the old fashioned way because I'll tell you what, no computer is safe," said the president-elect said when asked about the importance of cyber security. "I don't care what they say, no computer is safe. I have a boy who's 10 years old, he can do anything with a computer. You want something to really go without detection, write it out and have it sent by courier."
He dismissed U.S. sanctions against Russia, releasing a statement on Wednesday that "it's time for our country to move on."
"It's time for our country to move on to bigger and better things," Trump said. "Nevertheless, in the interest of our country and its great people, I will meet with leaders of the intelligence community next week in order to be updated on the facts of this situation."
