The Biden administration is poised to funnel millions of dollars in taxpayer cash to aid groups inside the Gaza Strip but is keeping the identities of those organizations a secret, making it difficult for congressional appropriators to determine if the money will enrich Hamas or other terror entities known to steal American aid dollars.

The White House earmarked at least $34 million in U.S. taxpayer funds for “confidential” nonprofits and United Nations agencies operating in the Gaza Strip, according to a review of U.N. funding channels by NGO Monitor, a watchdog group that tracks the international organization.

“This lack of transparency prevents congressional oversight and independent assessment of the ultimate recipients of U.S. government funding,” the watchdog group wrote in a briefing document earlier this week. “The potential for abuse in the Palestinian context is acute and indisputable.”
