President Donald Trump kicked off an unprecedented military-style parade in Washington, D.C.—commemorating the Army’s 250th anniversary and his 79th birthday—as millions across the country took to the streets to protest, rallying against his expanded immigration raids and a spending bill projected to slash healthcare access for millions.

The Philadelphia protest is something of a flagship demonstration amid nationwide actions as Trump holds a controversial military parade in Washington, D.C.

The demonstrations come on the heels of protests flaring up around the country over federal immigration enforcement raids that began last week and Trump ordering National Guard troops and Marines to Los Angeles where protesters blocked a freeway and set cars on fire.
