Hundreds of thousands of people turned out across the U.S. Saturday -- at more than 600 locations -- to rally for immigrant families and demand President Trump's administration reunite kids separated from their parents at the border.
Celebrities were among the masses at "Keep Families Together" marches in NYC, Washington D.C. and L.A. ... including Kerry Washington, Alysia Reiner, Amy Schumer, Padma Lakshmi, Lin-Manuel Miranda, America Ferrera and Lea Thompson.
