Haven't the press switched away from at least one of his conferences? I think it would be interesting for him to try to hold a press conference to see if the broadcast media would even carry it
I guarantee you that if he called into Fox, his comments would be carried by every media outlet and discussed exhaustively on Twitter.
For the record, if Trump called up Maggie Haberman and gave an on-the-record interview, I'm sure that would get covered too!
Be consistent, either refuse the cover the lies, or cover all of them. Don't just cover the lies that make you look good. Or more accurately: Don't just cover the lies that get lots of outrage (AKA views), without getting "too much" outrage of course, because that gets people killed.
The discussion around social media then gets split in two; what is currently legal, and what should be legal.
Trump probably doesn't have any current legal right to force Twitter (or CNN) to carry his message. But maybe there should be some laws about what Twitter can't moderate.
