Washington, May 2 (RHC)-- Tens of thousands marched in over 40 cities across the United States, including Chicago, New York, Washington D.C. and Los Angeles in what unions and civil rights groups called "A Day Without Immigrants" -- protesting Trump's crackdown on immigrants. 

Organizers of the actions said that the “Day Without Immigrants” is the first step in a series of strikes and boycotts that will change the conversation on immigration in the United States. 

Meanwhile, over 120 organizations came together for a "Resistance March" where thousands gathered in downtown Los Angeles to show "resistance, unity and defiance," before marching across the town to the City Hall.  According to Reuters, several thousand also assembled in Washington, DC's Dupont Circle to take part in a rally procession to Lafayette Square, across the street from the White House. 

International Workers Day saw large marches and rallies across the world, with unions, political parties and social movements taking demands for improved workers rights and social justice to the streets.  The day is commemorated as a national holiday in over 80 countries -- but not observed officially in the United States.
