US presidential candidate Donald Trump leaves after a joint press conference with Mexican President Enrique Pena Nieto (out of frame) in Mexico City on August 31, 2016.
Donald Trump was expected in Mexico Wednesday to meet its president, in a move aimed at showing that despite the Republican White House hopeful's hardline opposition to illegal immigration he is no close-minded xenophobe. Trump stunned the political establishment when he announced late Tuesday that he was making the surprise trip south of the border to meet with President Enrique Pena Nieto, a sharp Trump critic.

Donald Trump on Mexico: Then and Now
CNN —  

On Thursday morning, President Donald Trump tweeted this: “The Caravan is largely broken up thanks to the strong immigration laws of Mexico and their willingness to use them so as not to cause a giant scene at our Border. Because of the Trump Administrations actions, Border crossings are at a still UNACCEPTABLE 46 year low. Stop drugs!”

But, Trump’s claim that the caravan is breaking up as a result of any sort of actions by the Mexican government suggests that he doesn’t understand what the caravan actually is – and what they hope to accomplish.
