A second round of "No Kings" demonstrations are planned for Saturday, Oct. 18. Here's where events are scheduled in Washington state.

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."

More "No Kings Day" protests come amid a partial government shutdown and as Trump sends, or threatens to send, National Guard troops to Democrat-led cities.

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.

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

With chants, costumes and colorful signs, Washingtonians raised their voices against Trump's hard-line policies on immigration, the federal budget and more.

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 Pacific Northwest’s largest “No Kings” protest is set to take place in Seattle on Saturday, alongside several other rallies across western Washington.
