In an interview with NBC News earlier this month, a co-founder of the group known as Samidoun called Hamas’ Oct. 7 attack on Israel “a brave and heroic operation.”

A pro-Hamas organization that has helped organize protests on American college campuses is a “sham charity” that fundraises for a terrorist group, the Treasury Department said Tuesday.

In a joint action by the U.S. and Canadian governments, the Samidoun Palestinian Prisoner Solidarity Network, or Samidoun, was sanctioned by the Treasury Department and listed as a terrorist entity by the government in Canada, where it is based.

NBC News interviewed the co-founder of the group earlier this month. Charlotte Kates, Samidoun’s international coordinator, said that the Vancouver-based organization advocates for the rights of Palestinians, particularly those locked up in Israeli prisons.

But the Treasury Department said on Tuesday that Samidoun serves as a front organization and fundraiser for the Popular Front for the Liberation of Palestine, which the U.S. deemed a terror organization in 1997 and 2001.
