President Trump’s next chief of staff dismissed the then-candidate’s border wall and immigration views as “absurd and almost childish” in 2015.

“The fence doesn’t solve the problem. Is it necessary to have one, sure? Would it help? Sure. But to just say build the darn fence and have that be the end of an immigration discussion is absurd and almost childish for someone running for president to take that simplistic of [a] view,” Mick Mulvaney said in an interview with WHRI radio in South Carolina.
