A massive crowd gathered at City Hall in Philadelphia Thursday for a May Day rally and to see Vermont Sen. Bernie Sanders speak. The "For Workers, Not Billionaires" rally on the north side of City Hall drew a large crowd and shut down streets in the area.

After Sanders’s speech, protesters marched throughout the city and, in some instances, ignored requests by local police to clear the way for rush hour traffic.

Protesters will take to the streets in Philadelphia and elsewhere across the country to highlight the fight against President Donald Trump and his policies.
