NBC News' Jacob Soboroff reports from Los Angeles City Hall where thousands of protesters have gathered for a 'No Kings' protest against the Trump administration and ahead of the president's Washington D.

Thousands took to the streets in Pittsburgh and across western Pennsylvania, as well as the country, on Saturday as part of a demonstration deemed "No Kings."

Thousands are expected to turn out for "No Kings" rallies against President Donald Trump's actions. Here's how organizers and authorities are preparing.

The "No Kings Nationwide Day of Defiance" is planned to "reject corrupt, authoritarian politics in the United States," organizers say.

Additional celebrities including Anna Kendrick, Gina Rodriguez-LoCicero and Tessa Thompson were out on Saturday to protest against the Trump administration.

A bystander was fatally shot after security members at the demonstration confronted a man who was running toward the crowd with an AR-15-style rifle, the police said.

Between activism, election results and protest turnout, the prevailing political winds suggest the backlash to the president is real.

"No Kings" protests against the Trump administration are set to take place today in and around New York City as part of nationwide demonstrations. The protests coincide with Saturday's military parade in Washington,
