PORTLAND, Ore. (AP) — Demonstrators angry about the election of Donald Trump blocked traffic in downtown Portland and forced a delay for trains on two light-rail lines, joining protesters elsewhere in the country who swarmed streets in response to the election.

Reports said the crowd grew to about 300 people, including some who sat in the middle of a road. The crowd of anti-Trump protesters burned American flags and chanted, “That’s not my president.”

In Seattle, about 100 protesters gathered in the Capitol Hill neighborhood, blocked roads and set a trash bin on fire.

In Pennsylvania, hundreds of University of Pittsburgh students marched through the streets, with some in the crowd calling for unity. Campus protests also erupted at the University of Texas, the University of Connecticut, the University of California, Berkeley and other University of California campuses.

On Twitter, the hashtag “NotMyPresident” had been used nearly half a million times.

The Oakland protest grew to about 250 people by late Tuesday. Police Officer Marco Marquez said protesters damaged five businesses, breaking windows and spraying graffiti. No arrests were made.

A woman was struck by a car and severely injured when protesters got onto a highway, the California Highway Patrol said. Demonstrators vandalized the driver’s SUV before officers intervened. The highway was closed for about 20 minutes.

Oakland is a hotbed of violent protest in the San Francisco Bay Area. Two years ago, demonstrators briefly shut down two freeways, vandalized police cars and looted businesses when a Missouri grand jury decided not to indict a white police officer in the fatal shooting of a black teenager in Ferguson.

Nearly 80 people were arrested after a night in 2010 that saw rioters use metal bats to break store windows, set fires and loot after a white transit police officer was acquitted of murder and convicted of involuntary manslaughter in the slaying of an unarmed black man.

Elsewhere in California, more than 1,000 students at Berkeley High School staged a walk-out and marched to the campus of the University of California.

Students also walked out of two high schools in Oakland, a high school in Boulder, Colorado and a high school in Phoenix, Arizona.
