Don't enable him...

All of the networks should do two things when Trump is speaking live on television: 1) Run a chyron at the bottom of the screen during every Trump speech to fact check him in real time as he's speaking. And if that's not possible, then 2) immediately stop their broadcast of his speech and cut to something else. After every network starts doing one of these things in unison, then Trump will change his lying and self-aggrandizing behavior. For Trump, these media shows are political ads to his base and his way of stroking his own sense of self-importance. The media has to stop enabling Trump. All reporters should get up and walk out when Trump berates one their own, or when it's obvious that he's winging lies to have something seemingly (to himself) important to say.
