Trump is continuing his effort to convince his base that not only will “the wall” be built but also that it won’t cost them a cent in tax dollars because the Mexican government will pay for it. He repeated this claim on Saturday during a press conference — one day after requesting that Congress approve $18 billion in funding for the wall’s construction. “I believe Mexico will pay for the wall,” he said. “I have a very good relationship with Mexico. But yes, in some form, Mexico will pay for the wall.”
