Donald Trump says he'll meet with Mexico's president

WASHINGTON -- Donald Trump will make a surprise trip to Mexico on Wednesday to meet with the country's president hours before delivering a highly-anticipated speech on immigration.

Trump says on Twitter that he looks "very much forward" to meeting with President Enrique Pena Nieto. The Mexican leader had invited both Trump and Hillary Clinton to visit Mexico.

Pena Nieto's office says in its own tweet that the two men will meet in private Wednesday.
