Trump is upset that Hannity shows too many clips of people being mean to him:
Quote (Trump @ Billings @ MT rally)
DONALD TRUMP: Do we love Sean Hannity, by the way? I love him. But here's the only part. He puts up all these losers that say horrible things. I've got to talk to him. One after another. "Donald Trump, he's lost it up here." You know, it is pretty tough. I stand up here giving speeches for an hour and a half, many times without notes, and then they say "he's lost it," and yet we have 25,000 people showing up to speeches. And by the way, look at all the fake news back there.
