President Trump took his campaign for a wall to the US-Mexico border this week, hoping to drum up support for a $5.7 billion barrier while some federal workers struggle to survive without pay because of the government shutdown. Earlier, the president denied that he ever said Mexico would “write a check” to pay for the wall, which was a cornerstone of his campaign. Trump has also said the barrier could be built out of steel slats instead of concrete. In this podcast, Tamara Keith of NPR
examines the history of Trump’s wall and how his statements sometimes contradict each other.
