US military lawyers will help civilian prosecutors handle cases against undocumented migrants, the Defense Department said Wednesday, in a rare use of armed forces legal staff.
Under a "zero tolerance" policy, the United States has been arresting every illegal border-crosser but the measure has failed to stop the flow of migrants from impoverished and violent Guatemala, El Salvador and Honduras, as well as from Mexico.
From March to May this year, more than 50,000 people a month were apprehended for illegally crossing the boundary from Mexico.
In a statement, Army Lieutenant Colonel Jamie Davis, a Pentagon spokesman, said Defense Secretary Jim Mattis approved a request from the Department of Justice "to detail 21 attorneys with criminal trial experience to DOJ for a period of 179 days."
They will be appointed as special assistant United States attorneys and will focus on prosecuting misdemeanor improper entry and felony illegal reentry cases, Davis said.
NBC's Rachel Maddow reported that the military lawyers will be sent to Arizona, New Mexico and Texas.
US President Donald Trump reversed course on Wednesday and ordered an end to separation of migrant children from their parents on the US border, after domestic and international outrage, although he insisted his border policy will be just as tough.
