Pedro Pascal and Kerry Washington were among the A-list stars who joined the No Kings Day protests against President Donald Trump.

Protesters flooded into streets chanting, marching and waving homemade signs. Organizers said nearly 7 million people showed up for the demonstrations across the country.

Organizers said some 2,600 protests were planned in the U.S. on Saturday. The protests were largely peaceful, as demonstrators united in their stated aim to safeguard the country's democratic values.

"I served this country because I believe in the promise of freedom, equality and democracy,” one veteran said in the lead-up to the Oct. 18 "No Kings" protests nationwide.

The rallies were "just reinforcement of the view that Donald Trump should not be given a blank check to continue his lawless activities," Sen. Chris Van Hollen said.

The big picture: The typical attendee at the D.C. protest was an educated white woman in her 40s who heard about the event either through friends or via Instagram, according to preliminary data collected by American University researchers who track protest movements.

Protesters turned out at roughly 2,700 rallies around the country to celebrate free speech and protest many of the Trump administration's actions.

The demonstrations follow a wave of protests in June that organizers say drew more than 5 million people in cities across the country.
