Protesters filled streets in hundreds of cities across the US to oppose President Donald Trump’s administration on Saturday, as he held a military parade in Washington.

As a military parade rolls through Washington, DC, on Saturday – President Donald Trump’s birthday – millions of Americans are expected to protest in what organizers predict will be the strongest display of opposition to Trump’s administration since he took office in January.

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.

The protests coincide with a military parade in Washington D.C. to celebrate the 250th anniversary of the U.S. Army, Flag Day and Trump’s birthday.

The county's sheriff had made incendiary remarks about police response should any violence occur. But nothing happened.

Despite peaceful demonstrations reported in multiple cities, violence flared at some anti-Trump protests over the weekend.
