The families of Israeli hostages are suing Mahmoud Khalil and other Columbia University protest organizers for allegedly running Hamas' 'propaganda arm' on campus. The lawsuit, filed in the Southern District of New York on Monday, sues Khalil, a former Columbia graduate student who was the principal leader of Columbia University Apartheid Divest and a spokesman for the so-called 'Gaza Solidarity Encampment,' as well as Nerdeen Kiswani, the co-founder and chair of Within Our Lifetime; Maryam Alwan, a representative for Columbia Students for Justice in Palestine; and Cameron Jones, a representative for Columbia-Barnard Jewish Voice For Peace.
