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

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.

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."

Nearly 7 million protesters flooded into streets chanting, marching and waving homemade signs across the country.

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

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

At a “No Kings” protest in Washington, D.C., Bill Nye tells NBC News’ Melanie Zanona that federal cuts to science funding, especially around NASA, are “thoughtless.”

No Kings” demonstrations were planned across New England, the nation, and the world on Saturday, joining a string of protests against the Trump administration.
