"I regret and reject the decision of the United States to continue building a wall that, that for years, far from uniting us, divides us," Pena Nieto said in a taped message.

"The 50 Mexican consulates in the United States will convert into authentic advocates for the rights of migrants."
He did not address reports that he may be canceling next week's visit to Washington, D.C. But Mexican Foreign Affairs Secretary Luis Videgaray Caso said in an interview Wednesday night with Mexico's Televisa that Nieto's Jan. 31 visit is still confirmed.
