Mexican president reacts to Trump with caution

WASHINGTON (AP) — Mexican President Andres Manuel Lopez Obrador has reacted cautiously to a threat by President Donald Trump to close the border.

Trump tweeted today: "We build a Wall or ... close the Southern Border."

Disputes with Congress over funding for the border wall have already led to a partial U.S. government shutdown.

Today, Lopez Obrador said: "We are always seeking a good relationship with the United States. We do not want to be rash." Referring to the border wall funding dispute, he said "we have not commented on this issue, because it is an internal affair of the U.S. government."

Trump also threatened to cut off aid to Honduras, El Salvador and Guatemala, countries from which many migrants have fled.

Lopez Obrador said Mexico will defend migrants.
