Bernie Sanders headlines May Day protest in Philly

• Organizers say protests, marches, town halls and other actions are scheduled in nearly 1,000 cities across the country to rally against the "billionaire takeover" of the federal government.

Driving the news: For the Workers, Not the Billionaires May Day Rally kicks off at 4pm on the north side of City Hall.

• Sanders will join a coalition of labor unions, immigrant groups and workers' rights organizations during the event.
• The AFL-CIO Philly chapter is organizing the demonstration.

What they're saying: "This rally is not necessary exclusively against Trump, it's against all the bad bosses, billionaires, and oligarchs who are attacking the working class to further line their own pockets," Philly chapter AFL-CIO spokesperson Maggie Mullooly tells Axios.

By the numbers: Philly's rally is expected to draw upwards of 5,000 demonstrators, Mullooly says.

🚨 Traffic delays: The rally is likely to cause significant traffic delays during the afternoon rush hour.

• 🚧 Road closures will run from 3:15-7pm on streets around City Hall and along Broad Street from Chestnut to Vine Streets.
• 🅿️ Count on parking restrictions in the area, too.

Between the lines: Sanders' left-wing populism is fast becoming the touchstone for Democrat's new identity.

• Sanders and Rep. Alexandria Ocasio-Cortez have been barnstorming the country in recent weeks with massive rallies for a "Fighting Oligarchy" tour.
