(NBC, KYMA/KECY) - Opponents of President Donald Trump's administration started coming out the streets to rally in hundreds of cities Saturday.

Hundreds to thousands marched in Downtown Atlanta and beyond Saturday, calling for immigrant protections and rejecting authoritarianism.

"No Kings" protests are scheduled in at least 15 Georgia cities, including Atlanta, Athens and Marietta.

In Greenville, South Carolina about 5,000 as demonstrators gather at Unity Park to support Veterans and protest against the Trump Administration's policies.
