As a military parade rolls through Washington, DC, on Saturday – President Donald Trump’s birthday – millions of Americans are expected to protest in what organizers predict will be the strongest display of opposition to Trump’s administration since he took office in January.

Thousands gathered in downtown Rock Hill on Saturday for a “No Kings” rally and march, joining national demonstrations coinciding with Flag Day and a military parade in Washington, D.C., by President Donald Trump to honor the U.S. Army’s 250th anniversary.

A day of nationwide defiance." It called today's celebration in Washington D.C., a "spectacle meant to look like strength." The protest in Savannah was hosted by Coastal Georgia for Democracy and the Savannah Chapter of the Democratic Socialists of America.

Thousands marched from City Island to Riverfront Park as part of the national “No Kings” protest movement calling for democratic reform.

The rallies coincide with a Washington, D.C., parade celebrating the 250th anniversary of the U.S. Army and President Donald Trump's 79th birthday.

Protests against the Trump administration, which are set to continue this weekend after a week of uprising that spread from Los Angeles across the country, have energized a portion of the left-wing base that has been despondent since President Trump’s election.
