'You really think he's insane?' Senator loses it when pressed by Anderson Cooper on Trump

Sen. Ruben Gallego (D-AZ) was beside himself in an interview on CNN about President Donald Trump's latest threats to annex Greenland, calling the president a "madman" who is divorced from reality and needs to be treated as such.

"This is a man, again, that only cares about himself," Gallego told Anderson Cooper. "First, he doesn't like commitment to other countries that are based on alliances, based on trust, because this man has no trust in anybody else, and he would rather just break whatever he can to get what he wants.
