Dozens of protests and rallies against the Trump administration are set to take place in the Bay Area this weekend, as part of the nationwide "No Kings" movement.

Hundreds of people gathered at Ocean Beach in San Francisco on Saturday morning to protest the Trump administration by forming a massive human banner.

Motorists in two cities across the nation have struck “No Kings” protesters, according to multiple reports. Police detained two motorists whom they say intentionally drove into crowds of protesters in San Francisco, California and Culpeper, Virginia. There is no reason to believe the two incidents are connected.

Alphabet-owned robotaxi company Waymo is limiting service due to Saturday’s scheduled nationwide “No Kings” protests against President Donald Trump and his policies.

Peter Hosey is the organizer of the San Francisco "No Kings" protest. He's gathering people to the grass at Mission Dolores Park on Saturday. "We want to give people a chance to show up in the streets, in mass and great numbers, and take our message to the people," he said.

The demonstrations come on the heels of protests flaring up around the country over federal immigration enforcement raids that began last week and Trump ordering National Guard troops and Marines to Los Angeles where protesters blocked a freeway and set cars on fire.
