With less than 24 hour notice, Republican presidential candidate Donald Trump accepted an open invitation from Mexican President Enrique Peña Nieto to visit the country less than 70 days before the U.S. election and on the same day Trump is set to deliver a pivotal speech on immigration in Arizona.

The two men will meet behind closed doors at the Mexican President’s official residence, called Los Pinos, early Wednesday afternoon and issue a statement immediately after without taking questions from reporters.

In an interview with CNN in July, Peña Nieto said there was “no way” Mexico would pay for a border wall. The GOP candidate only enjoys a 4 percent favorable rating from Mexican citizens, according to a Reforma newspaper poll published August 16.

The surprise event, closed to the public, is already engendering calls for a massive protest of the candidate who decried that Mexico is sending “rapists” and “criminals” across the border illegally.
