To stay in America, millions of undocumented immigrants turned over their personal details to the government on the promise Washington wouldn't use it against them. Now, Trump has betrayed that promise. Julián Gustavo Gómez knew it would happen.

Gómez is a former DACA recipient—he received his green card just a few weeks ago—a proud American, and the Director of Campus Engagement for Define American, a non-profit working to change the way Americans view immigrants. Weeks after Trump's election in 2016, The Washington Post published an op-ed from Gómez in which he asked the Obama administration to delete the DACA database. He knew Trump would use it as a weapon.
