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.

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.

Multiple protests took place across the region on Thursday. In Philadelphia, 70 protesters were arrested for blocking the road a few blocks from City Hall.
