Trump, on Sunday: "Whenever you see the words 'sources say' in the fake news media, and they don't mention names, it is very possible that those sources don't exist but are made up by fake news writers. #FakeNews is the enemy!"
Trump, on Tuesday: Retweeted a Fox News article citing anonymous sources to claim that Jared Kushner had not suggested a communications channel with Russia in a meeting, which goes against most of the reporting on the subject.
Why it matters: Back in January, Axios asked Trump if he was worried that calling the media "fake news" would cause problems down the line when he needed people to believe a piece of reporting. At the time, Trump replied: "I hadn't thought of it that way, no."
