“They’re very dishonest people,” he added. “In fact, in covering my comments, the dishonest media did not explain that I called the fake news the enemy of the people — the fake news. They dropped off the word ‘fake.' And all of a sudden the story became the media is the enemy. They take the word ‘fake’ out. And now I’m saying, ‘Oh, no, this is no good.’ But that’s the way they are.”
