"While Trump’s statement suggests he views the border wall as a security necessity, comments he made during a conversation with Mexican President Enrique Peña Nieto days after his inauguration indicate Trump’s motivation for pushing for the wall has to do with politics, not national security. During that January 27 conversation, a transcript of which was leaked to the Washington Post, Trump characterized the wall as “the least important thing that we are talking about, but politically this might be the most important [thing we] talk about.” When Nieto indicated his government has no interest in helping Trump fulfill his campaign promise by paying for the wall, Trump said he understood, but couldn’t say so publicly, and urged Nieto to do the same. “You cannot say anymore that the United States is going to pay for the wall,” Trump told Nieto. “I am just going to say that we are working it out"."
