Report: Trump says he will travel to Mexico Wednesday to meet with Pena Nieto

The Washington Post reported that Republican presidential nominee Donald Trump was considering a trip to Mexico Wednesday, hours before he is scheduled to give a major speech on immigration.

The Post story said Trump was considering the meeting with Mexican president Enrique Pena Nieto. The meeting would take place in advance of a speech many see as an attempt to clarify his stance on undocumented aliens.

According to a report from Reuters, Pena Nieto said earlier in the month he would meet with Trump, despite the fact he has compared the New York billionaire with Adolf  Hitler and Italian dictator Benito Mussolini.

"Yes, I would meet with him," Pena Nieto said, referring to Trump in a pre-taped television interview broadcast on Tuesday night.

"I have never met him. I can't agree with some of the things he has said, but I will be absolutely respectful and will seek to work with whomever becomes the next president of the United States."

Reports say Pena Nieto issued invitations to both Trump and Democratic nominee Hillary Clinton to visit the country.

According to the Post story, the possibility of a trip by Trump was first raised with the U.S. embassy in Mexico City earlier this week, a source said.

Trump is set to give his speech in Phoenix at 6 p.m. local time.
