Here's another example of the president getting his earliest daily briefing from cable news:

122 vicious prisoners, released by the Obama Administration from Gitmo, have returned to the battlefield. Just another terrible decision! — Donald J. Trump (@realDonaldTrump) March 7, 2017

And here's the inspiration, via Fox and Friends:

Why it matters: As Trump continues to rage against the establishment press, he'll increasingly follow the story lines from conservative media, meaning this will only intensify.

Why it matters even more: As Miami Herald reporter Carol Rosenberg pointed out to Trump on Twitter, that 122 number isn't correct. Of those 122 Trump claimed were released by President Obama, 113 were released under President George W. Bush.
