At Berkeley High School in California, about 1,500 students walked out of classes Wednesday morning -- some carrying signs critical of Trump -- and marched toward the UC Berkeley campus, according to Charles Burress, a spokesman with Berkeley Unified School District.
Similar protests were reported at other schools and college campuses across the nation.
Pop star Lady Gaga, a vocal Hillary Clinton supporter who had performed at the Democratic candidate's final rally in North Carolina, stood atop a sanitation truck outside Trump Tower in New York, brandishing a sign that read: "Love trumps hate."
