MSNBC’s Ali Velshi quickly destroys Trump for brazenly lying about building his ‘beautiful’ border wall

MSNBC's Ali Velshi didn't mince words after President Donald Trump insisted on Friday that his proposed border wall was already under construction, lambasting the "lying" president for living in a fantasyland in which he "can do whatever he wants to do" without any input from Congress.

"That is the president of the United States lying again about a wall. Let me, please, just tell you what's actually going on," Velshi began. "It's just an absolute provable lie."

Velshi came armed for bear, offering viewers a thoroughly detailed description of the "1954 miles of border between the United States and Mexico."

"As of February, there will be 14 new miles of wall, that's been authorized by Congress," he said. "But when the president says 'we're building walls, there's walls going up, there's new wall going up,' I just need you all to understand, this is an absolute provable lie."

He added that even if there was any construction going on, that in itself "would be illegal because it's not actually authorized by Congress."

"As much as Donald Trump thinks he can do whatever he wants to do," Velshi sneered, "you can't actually build a wall between Mexico and the United States without appropriations from the Congress of the United States.
