Thousands of protesters flooded Bay Area streets Thursday for May Day – many of them holding signs with slogans declaring “resist fascism” and “impeach Trump” – in a rebuke of Trump administration actions, marking the third such mass mobilization in recent weeks.

May Day protests were set to sweep the Bay Area on Thursday from San Jose to Oakland on the international day dedicated to supporting workers. May Day often draws rallies and protests in support of labor. Many of the protests planned for Thursday are also aimed against the Trump administration.

Organizers in San Jose were finalizing preparations for Thursday’s May Day protest, which is set to bring big crowds. This year’s protest will highlight major changes in immigration police. Organizers have called on immigrants to skip school or work to highlight just how much that community contributes to the country.
