Republican presidential nominee Donald Trump is slated to meet with Mexican President Enrique Peña Nieto on Wednesday, in a seemingly last-minute visit by the real estate mogul prior to a speech his campaign said would provide more insight on his immigration policy.

Trump's campaign began with him accusing Mexico of "sending criminals and rapists," and a vow to make the country pay for a wall between itself and the US.
