The Trump administration is set to begin using DNA testing to verify whether migrants traveling as families are in fact related in an effort to target human trafficking at the border.

"This is part of a larger investigative process. This is not screenings, this is not just random application of this, this is a pilot designed to assess the usefulness of this technology in an investigative process," Immigration and Customs Enforcement acting Deputy Director Derek Benner told CNN in a statement.

The program is meant to cut down on migrant groups posing as family units, CNN noted.

It comes as the U.S. has faced a swell of apprehensions at the southern border, particularly of family units, in recent months.

Customs and Border Protection chief Kevin McAleenan said in March that the surge had driven his agency to its "breaking point."
