The Republican governors of Texas, Arizona and New Mexico on Monday committed 1,600 Guard members to the border, giving President Donald Trump many of the troops he requested to fight what he's called a crisis of migrant crossings and crime.
The only holdout border state is California, led by Democratic Gov. Jerry Brown, who has not announced whether troops from his state's National Guard will participate and has repeatedly fought with Trump over immigration policy.
New Mexico Gov. Susana Martinez's office said that more than 80 troops would deploy later this week -- the first of an expected 250 Guard members from New Mexico to serve on the border.
Under the federal law Trump invoked in his proclamation calling for National Guard troops, governors who send troops retain command and control over their state's Guard members and the U.S. government picks up the cost.
Trump has said he wants to use the military at the border until progress is made on his proposed border wall, which has mostly stalled in Congress.
