'Keep Families Together' March Draws Celebrities Nationwide

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.

John Legend and Chrissy Teigen were in attendance in L.A., and the singer gave a short speech about not giving up the fight for families before debuting a new song.

"Orange is the New Black" actress Diane Guerrero also gave an impassioned and tearful speech in D.C. about her own experience of getting separated from her parents when she was 14.

Though the Prez signed an executive order to keep immigrant families together 10 days ago, protests have not died down ... because progress has been reportedly painfully slow.
