HOUSTON — Republican governors of three Southwestern border states on Monday committed 1,600 National Guard members to the US-Mexico border, giving President Trump many of the troops he requested to fight what he has called a crisis of migrant crossings and crime.

Arizona, New Mexico, and Texas all made pledges that add up to almost half of the up to 4,000 troops Trump sought. Some Guard members started arriving at the border as state and federal officials continued to discuss what they will do.

The only holdout was California, led by Democratic Governor Jerry Brown, who has not said if his state’s National Guard will participate. He has repeatedly fought with Trump over immigration policy.

Mexico’s foreign relations secretary said his government is evaluating its cooperation with the United States. Luis Videgaray said he will give results of the analysis to President Enrique Pena Nieto in coming weeks.
