Republican presidential nominee Donald Trump plans to detour from the campaign trail on Wednesday to visit Mexico and meet with President Enrique Pena Nieto at his invitation, a surprise trip scheduled just hours before Trump delivers an immigration policy speech in Arizona. Nieto and Trump each confirmed late Tuesday that Trump accepted the invitation and the two would meet in private Wednesday. Campaign manager Kellyanne Conway told Fox News the two would discuss illegal immigration, trade and drugs. Trump running mate Mike Pence also said they would begin a conversation about a proposed border wall, along with other issues.
