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."

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.”

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

Thousands of "No Kings" protests are scheduled for Saturday, with millions expected to take to the streets. Here's how you can watch the demonstrations live.
