The Trump administration on Tuesday announced it would end a government program that protects children who were brought to the United States illegally from being deported — but it’s essentially leaving Congress a six-month window of time to try to save it.

The legal shield is known as Deferred Action for Childhood Arrivals, or DACA, and since its enactment in 2012, it has allowed roughly 800,000 undocumented young adults to live in the United States and obtain work authorizations every two years.
