Ann Coulter blasts Trump as a 'lazy and incompetent lunatic' in latest angry tirade

Ann Coulter, an infamously estranged backer of President Donald Trump, is continuing to hammer the president over his inability to build a wall along the U.S.-Mexico border.

During an interview with Yahoo News' Mike Isikoff, Coulter admitted that Trump was very bad at being president while also suggesting that he might not be all there mentally.

"We put this lunatic in the White House for one reason," said Coulter of Trump and the border wall.

The right-wing pundit also described Trump as "lazy and incompetent," but she predicted that he would eventually decide to build his border wall via executive action even if Congress refused to fund it.

What's more, Coulter believes that Trump doesn't even have to declare a national emergency -- rather, he can use his powers as commander-in-chief to simply order the military to construct it.

"I think Trump is gonna do that," Coulter predicted. "I think he’s finally going to pull that pocket Constitution out of his lapel pocket and [say], 'Oh my gosh, I’m the president. This is great.'"

Harvard Law School professor Lawrence Tribe, however, immediately shot down Coulter's claims that the president could order the wall built without congressional authorization.

"Inherent presidential power as commander-in-chief doesn’t give Trump the power of the purse," he wrote on Twitter. "We fought a revolution to end such power."
