The biggest single-day mobilization of resistance since President Donald Trump returned to office is expected Saturday, June 14, with "No Kings" protests in cities across the U.S.

Protesters across the North Bay have started taking to the streets as part of a nationwide wave of rallies Saturday opposing President Donald Trump and what they call a rising threat of authoritarianism.

No Kings protests are happening in Tennessee in response to President Donald Trump's military and birthday parade and speech.

The Houston demonstration is one of several planned in the region throughout the day and is expected to draw thousands of protesters.

No Kings” organizers described the events as a “nationwide day of defiance” against President Donald Trump and authoritarianism.

Tens of thousands of demonstrators took to the streets across Southern California on Saturday to voice their concerns over ongoing immigration raids and oppose the policies of President Trump, who they depicted as an aspiring monarch.

While President Donald Trump attended a military parade he ordered on his birthday to recognize the 250th anniversary of the U.S. Army in Washington, D.C., thousands of people in the Kansas City metro area flexed their First Amendment right Saturday to voice their opposition to polices of the Trump administration during the “No Kings” national day of defiance.

Social media users slammed CBS News for seemingly advertising "No Kings Day" protest merchandise ahead of anti-Trump demonstrations, calling the move unethical amid controversies.
