President Trump on Saturday paused from his holiday break to slam the news media on Twitter.

“I use Social Media not because I like to, but because it is the only way to fight a VERY dishonest and unfair ‘press,’ now often referred to as Fake News Media,” he posted at 5:42 p.m.

“Phony and non-existent ‘sources’ are being used more often than ever,” he continued. “Many stories & reports a pure fiction!”

The broadside came hours after a New York Times report — based on anonymous sources — alleged that former campaign aide George Papadopoulos triggered the 2016 FBI investigation into Trump’s relationship with Russia.

Papadopoulos allegedly blabbed to an Australian diplomat in May 2016 that Russian sources had political dirt on Hillary Clinton.

When WikiLeaks posted a series of Democratic National Committee emails a couple of months later, the Australians told the FBI of the conversation, the Times said.

Trump also plans to declare a “2017 King of Fake News” this weekend, his campaign committee told supporters in a Thursday email.

The president spent five hours at his Trump International Golf Club on Saturday, but White House staffers did not disclose his activities there.
