U.S. Border Patrol stretched thin as caravan heads north, chief says

“Obviously the system is beyond capacity right now,” McAleenan said, with the Border Patrol responsible for transporting and caring for asylum seekers.

“I’d like to free up my officers and agents to do law enforcement work. That’s what they’re trained for, that’s what the American people need them to do on the front line to address security risks,” he said…

McAleenan said he plans to send special response and tactical teams to the border ahead of the caravan, likely to large ports of entry where the migrants might attempt to cross. They will be joined by 800 troops the Pentagon is deploying to assist.
