text: CNN's Don Lemon called President Trump a liar, petty, and devoid of the facts after he held a rally Tuesday night in Phoenix. Lemon also questioned Trump's fitness for office and if he is "stable." "He's unhinged, it's embarrassing and I don't mean for us, the media because he went after us, but for the country," Lemon said. "His speech was without thought, it was without reason, it was devoid of facts, it was devoid of wisdom. There was no gravitas. There was no sanity there," Lemon said.
