Watch: New Yorkers Hold Anti-Trump Rally In Union Square To Protest Muslim Ban

UNION SQUARE, NY — New York City activists rallied on Thursday night to protest the U.S. Supreme Court's recent decision to partially uphold part of a federal travel ban.

New Yorkers have been protesting President Donald Trump's immigration agenda since he first signed an executive order in January prohibiting travelers from seven predominantly Muslim countries. The same order also halted America's processing of refugees for 120 days.

The ban, which was being rolled out at airports throughout the country in January, spurred massive protests at John F. Kennedy Airport and throughout the city while people were detained and questioned after arriving in the U.S.

After a complex legal back-and-forth, Trump's original order was blocked by a federal appeals court. Trump issued a revised executive order in March which prohibited citizens of six of the original seven countries — Iran, Libya, Somalia, Sudan, Syria and Yemen — from traveling to the U.S. for 90 days.

In its review of this order, the U.S. Supreme Court elected to partially reinstate the ban before hearing arguments for and against it in October. The court stipulated that the ban could not be applied to anyone with "a credible claim of a bona fide relationship with a person or entity in the United States."

Protesters gathered in Union Square Park Thursday evening to protest what they're calling "Trump's Muslim Ban 3.0."

"Donald Trump does not get to decide who is family or what is love," organizers said on Facebook. "It's up to us now to fight back against this latest attack and stand up for the values that truly make America great: opportunity and justice for all."

The rally's organizers made note of the State Department's reported guidelines for the ban. Because the Supreme Court did not define what a "bona fide relationship" is, the Trump administration has defined which relatives are, or are not, allowed to visit relatives in the U.S., the New York Times reported on Wednesday. Enforcement of the new guidelines begins at 8 p.m. on Thursday, according to the Times.

"Bring your grandparents, cousins, fiances, aunts, uncles, nieces, nephews (all barred under Trump's orders) to Union Square Park, North Side, today at 5:30 p.m.," organizers said.

Thursday's rally was organized by the New York Immigration Coalition and Make the Road New York. Activists have planned a town hall immediately after the rally.

The Department of Homeland Security released partial guidelines on Thursday evening less than two hours before they were scheduled to go into effect.

"We expect no disruptions to service," officials said in a statement.
