U.S. President-elect Donald Trump answers questions from reporters accompanied by his wife Melania for a New Year's Eve party December 31, 2016 at Mar-a-Lago in Palm Beach, Florida.

The president-elect took another swipe on Tuesday at the intelligence community that will be under his command in just a few weeks, once again in a tweet.

Last week Donald Trump had said he would meet with high-level intel briefers this week to hear more about Russian hacking of the U.S. election.

Trump Promises New Revelations on Russian Hacking

Trump antagonized the intelligence community over the weekend, telling reporters gathered outside his New Year's Eve party that hacking is a "very hard thing to prove" and that he knows "things that other people don't know, and so [intelligence officials] cannot be sure of the situation." Trump promised to reveal what he proclaims to know Tuesday or Wednesday.

On Tuesday, Trump tweeted, "The 'Intelligence' briefing on so-called 'Russian hacking' was delayed until Friday, perhaps more time needed to build a case. Very strange!"

The "scare quotes" around the words intelligence and Russian hacking seem to reflect Trump's previously stated position that it's nearly impossible to know who hacked what and when — although intelligence experts both inside and outside of the government dispute that claim.
