Hundreds of immigrant youth descended upon the Hart Senate building Thursday afternoon, gathering in mass protest of the Trump administration’s decision to rescind the Deferred Action for Childhood Arrivals Act, according to The Daily Caller.

The immigrants gathered in the Capitol to demand that members of Congress pass legislation for DREAMERers and DACA recipients.

Students across the U.S. staged organized walkouts and rallys Thursday in protest of the Trump administration’s decision to rescind DACA.

Another group, the UndocuBlack Network, joined in on Thursday’s Capitol protests. UndocuBlack describes themselves as a “multigenerational Network of Black undocumented people organizing our communities and building power.”
