Mexican President Enrique Pena Nieto and President Donald Trump agreed to stop publicly talking about who would pay for a border wall during a phone call Friday, representatives of both governments said, putting at least a partial lid on a feud that has threatened to rupture one of the world's biggest bilateral trade relationships. The Mexican and U.S. governments released joint statements describing the hour-long call "productive and constructive" a day after the two leaders exchanged tweets and Pena Nieto canceled a planned visit to the White House to iron out differences.
