Speaking at a "No Kings" rally in Washington, D.C., Bill Nye, the former host of "Bill Nye the Science Guy," urged lawmakers to “stop the abuses of this petulant president [Trump] and his circle of sycophants,” declaring, “No thrones, no crowns, no kings."

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

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.

Gov. Bob Ferguson struck a defiant tone at the No Kings day rally in Everett, Washington, where thousands of people attended on Saturday.

Dozens of "No Kings" rallies are scheduled across western Washington for Saturday, Oct. 18, from Bellingham to Vancouver, to the San Juan Islands.

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.
