PORTLAND, OR -- Thousands protesting Donald Trump's victory in the presidential election took to the streets for a second night of demonstrations and vigils in several US cities.
The anti-Trump rally in Portland, Oregon, revved up as protesters confronted police.
What started out as a peaceful march, with more than 4,000 people, quickly turned violent.
Over the course of the evening, "anarchists" from within the crowd threw projectiles at officers, vandalized local businesses and damaged cars, Portland Police Sgt. Pete Simpson said.
Police publicly declared a "riot" due to "extensive criminal and dangerous behavior" and called the protest "unlawful" according to tweets on the police department's Twitter page.
The crowd was dispersed using "less lethal munitions" and at least 26 protestors were arrested, police said.
Protests and marches continued in other US cities including Los Angeles, Philadelphia, Denver, Minneapolis, Baltimore, Dallas and Oakland, California.
Trump took to Twitter to call the demonstrations that first developed on Wednesday "very unfair."
The mood in the streets where protesters marched was as varied as the locations.
Most of the demonstrations were peaceful, if not tense and somber.
In Philadelphia, protester Deb Bentzel said that "as a woman and someone who believes all people, regardless of their race, religion or citizenship status should be supported and embraced by this country," she marched to reject "the racism, hate, misogyny and fear that this man (Trump) projects and fosters in others."
