Donald Trump, who has routinely assailed Mexican immigrants, will meet Enrique Peña Nieto on Wednesday ahead of major immigration speech

Washington

: Donald Trump announced he will travel to Mexico on Wednesday to meet with the country's president, just hours ahead of the Republican White House hopeful's much-anticipated Arizona speech on immigration.

"I have accepted the invitation of President Enrique Pena Nieto, of Mexico, and look very much forward to meeting him tomorrow," Trump posted on Twitter.

Trump has routinely assailed Mexican immigrants who illegally cross the border into the United States, and he has made hardline immigration policies, including calls for deportations, a key plank of his campaign.
