Early Tuesday morning, Columbia student protesters took over a building on campus, pledging not to leave until their demands—for the university to divest from Israel, financial transparency from Columbia’s endowment, and amnesty for pro-Palestinian protesters—are met. The group of “autonomous protesters” took over Hamilton Hall, an academic building on the Morningside Heights campus, shortly after midnight, according to a media advisory from Columbia University Apartheid Divest, the group that organized the Gaza Solidarity Encampment over the past few weeks.
