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 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

The Department of Homeland Security said Friday that it has requested the Pentagon provide thousands of National Guard troops to bolster efforts to remove undocumented migrants from the United States.
