“Donald Trump says, build a wall. Deport all illegal immigrants. Rules are rules. You either play and stay or you cheat and you get deported. What challenges does this plan pose?” Patti Mercer asked in the August 25, 2015, interview on WRHI radio in South Carolina.

“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,” Mulvaney added, without making a distinction between a fence or wall.
