Approved by a 219-184 margin last Thursday along party lines, the measure has activists worried that it will be used to stifle legitimate criticism of Israel’s genocidal war on Palestinians.

GOP Congressman Thomas Massie was the lone Republican to oppose the legislation; 15 Democrats voted in its favor.

Among other things, the bill grants the U.S. Treasury Department unilateral authority to strip non-profit groups of their status if it deems them to be a “terrorist supporting organization.”

Anti-war and other voices are concerned that the term is not specific enough and that non-profits that draw attention to Israel’s war crimes in Gaza will be discriminated against.
