The request, which is under review by the Pentagon, is part of a renewed push by the Trump administration to ramp up arrests of undocumented migrants

WASHINGTON (AP) — The Department of Homeland Security has asked for 20,000 National Guard troops to assist with immigration roundups across the country, and the Pentagon is reviewing the unusual request, a U.S. official confirmed to The Associated Press.

The Department of Homeland Security asked the Pentagon for the troops to secure the border, two U.S. defense officials said, a potential escalation of the Trump administration’s use of the military in its immigration crackdown.
