Trump's border wall campaign promise is 'tumbling down' and he's 'trying to stick us with the tab'

Acosta on Tuesday described Donald Trump's backtracking on his signature campaign promise to "build the wall" and make Mexico pay, telling host Wolf Blitzer it's clear the president is "trying to figure out how to stick all of us with the tab."

"The president is also scrambling a way to pay for the wall on the border, floating the idea of taking the money from the just-approved budget for the Pentagon," Acosta reported on Monday. "The White House wouldn't confirm that, perhaps because that would be a sign of a key campaign promise that's tumbling down."
