Protests Erupt After Donald Trump Presidential Projection

— -- Protests erupted across California early this morning after Donald Trump was projected to be the next president of the United States.

Although there were protests elsewhere in the country — including Washington, D.C. — because of the late hour when the projection was made, the West Coast appeared to have the most activity.

In Oakland — where police said 60 to 70 protesters gathered in the city's downtown — a female protester who was blocking traffic suffered major injuries after being hit by a car on Highway 24, California Highway Patrol spokesman Sean Wilkenfied confirmed to ABC News.

Protesters — who were met by police officers carrying long batons and wearing helmets, gas masks and other riot gear — set small fires on the street as well.

Four engine companies from the Oakland Fire Department responded to extinguish the fires, a battalion chief told KGO-TV in San Francisco.

KGO-TV reported that "a small number of arrests for disobedience and vandalism" were made, according to police.

In Southern California, dozens of students at UCLA took to the campus and nearby streets chanting "F--- Donald Trump," among other disparaging comments, according to KABC-TV in Los Angeles. Officials said 1,500 to 3,000 students marched through the campus.
