At the same time, the administration would put in place new rules that would disqualify migrants who cross the border in between ports of entry from claiming asylum, according to those briefed. No one at CBP, including the Border Patrol, endorses this activity. The troops are also expected to provide tents and medical care for Border Patrol agents and other officers patrolling the border.
The official said the troops would satisfy elements of a "wish list" for military assistance sent to the Pentagon by the Department of Homeland Security, the United States agency with responsibility for the border.
But four days after crossing into Mexico, the caravan is still more than 3,000 kilometers (1,860 miles) from the United States border.
President Donald Trump is weighing a range of possible options created to prevent undocumented migrants from crossing the US-Mexican frontier, according to a White House official familiar with the discussions. There are 2,200 national guard troops now serving on the border; 1,145 soldiers in Texas, 115 in New Mexico, 580 in Arizona and the remaining 360 in California. He says those trying to enter the U.S.

Numerous migrants are fleeing poverty and insecurity in Honduras, where powerful street gangs rule their turf with brutal violence.
The action, if implemented, would effectively bar those seeking asylum from entering the country. Kirstjen Nielsen, the Homeland Security secretary, who has briefed Trump about the caravan as well as data showing a large uptick in the number of apprehensions at the border over the past year, has been leading the effort.
The planned deployment of active-duty troops is in response to a request from the Department of Homeland Security, which manages the Border Patrol.
