DACA recipients – often called DREAMers – are facing a new nightmare. According to the Trump administration, Immigration and Customs Enforcement (ICE) officers may use the information these people gave the government as a means of gaining temporary protection to, instead, find and deport them.

In deportation proceedings, the government must prove that the person they want deported is in the U.S. illegally. That can sometimes be tough. DACA recipients – nearly 800,000 of them – gave the Department of Homeland Security information proving they are undocumented so they could get relief from the threat of deportation. They also gave the government information about where they live, work, and go to school. As soon as Donald Trump was elected, immigrants’ rights activists started asking what his administration would do with that information.

In a memo, the Department of Homeland Security answered this question. And its statement – full of wordy legalese – made clear that Immigration and Customs Enforcement officers will be able to use DACA recipients’ personal information to deport them.
