As part of an Alternative to Detention (ATD) program, the Department of Homeland Security (DHS) is handing out cellphones and ankle monitors meant to track individuals who crossed the border to ensure they show up for scheduled court dates, White House press secretary Jen Psaki confirmed at a press briefing April 6.

Psaki said Immigration and Customs Enforcement (ICE) takes a biometric voice print of an illegal border crosser before issuing them a phone and releasing them into the United States. She said the federal government is then able to confirm an individual's voice during a check-in call or track the individual using GPS or facial matching technology with a smartphone or tablet. She said some are also tracked via an ankle bracelet.
