The Tides Foundation, a left-wing dark money giant backed by George Soros and other progressive billionaires, bankrolled the fiscal sponsor of the Samidoun Palestinian Prisoner Solidarity Network, an anti-Semitic group sanctioned in the United States for providing financial support to terrorists, according to newly released tax forms.

The foundation reported in its latest Form 990 tax return that it granted $286,000 to the Alliance for Global Justice in 2023, a group best known for serving as the fiscal sponsor of Samidoun.

The Treasury Department in October sanctioned Samidoun as a “sham charity” that provided material support to a Palestinian terrorist organization that participated in the Oct. 7 Hamas terrorist rampage in Israel.
