Thousands of New Yorkers have filled Washington Square Park this evening for an "emergency rally" for immigrant and Muslim rights, in the wake of a series of executive orders issued by President Trump this afternoon. The turnout, according to some of those in the park now, is "massive."

This afternoon, Trump, as promised, issued an executive order threatening to cut federal funding to sanctuary cities that have refused to aid his administration in their promised attempts to round up and deport immigrants. The order is short on specifics, but here's what we know so far. Trump also signed an executive order for the construction of a wall along the United States border with Mexico, and is expected to issue another barring refugees from Middle Eastern countries, most of which have been bombed by the U.S.

CAIR-NY, which announced the rally this morning, says the protest is intended to send a message that, as "a city of immigrants, we cannot stay silent in the face of such hate. We ask you to gather tonight (Wednesday), to show President Trump that all New Yorkers stand with our Muslim and Latino neighbors. Together, we will form a beacon of light against the coming darkness."

We'll have more later from the rally, which is happening until at least 8 p.m., as well as a report from Mayor Bill de Blasio's last-minute press conference addressing Trump's executive order and how it could impact NYC.
