May Day marches peaceful in Seattle

Hundreds gathered and marched in what were largely peaceful demonstrations on May Day in Seattle on Tuesday.

The big March for Workers and Immigrants' Rights kicked off with a rally at Judkins Park and ended in downtown Seattle.

In the afternoon, Seattle police said a masked man was arrested for throwing a rock at The Amazon Spheres.

Thousands across the country last year peacefully chanted, picketed and protested against President Donald Trump's immigration and labor policies on May Day, despite a small pocket of violent unrest in the Pacific Northwest where police made arrests and shut down protests.

Marchers in Seattle Tuesday carried signs reading "Resist Trump" and "No Wall, No Raids, No War." Other groups made up of far-right Trump supporters also marched through Seattle.
