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

The Washington Post editorial board in a new column says the 'No Kings' protests, like the tea party of 2009, are a warning to the president.

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."

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.

President Donald Trump denied being a 'king' after weekend protests, calling demonstrators "whacked out" while Democrats like Chuck Schumer defended the rallies.

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.

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.”
