What to know about campus protests:

    More than 2,000 people have been arrested at pro-Palestinian protests at colleges across the country in the last two weeks.

    At UCLA overnight, 210 people were arrested when officers cleared an on-campus encampment in a chaotic scene, officials said.

    New York City officials said that a significant number of people arrested this week at campus demonstrations were not affiliated with the schools. Nearly 30% of the people arrested at Columbia were unaffiliated with the university and 60% of the arrests at City College involved people who weren't affiliated with that school, the mayor said.

    Dozens of people have been arraigned in New York. The district attorney said 46 people who were detained at Columbia have been charged with criminal trespass and 22 people detained at City College were arraigned on one count burglary and obstructing governmental administration.

    President Joe Biden addressed the protests from the White House, saying students had a right to dissent but not a right to cause chaos.
