Stop Taxpayer Funding of Hamas Act

This bill prohibits U.S. government spending in Gaza territory until the President certifies to Congress that funds won't benefit Hamas, designated terrorist groups, or entities controlled by them. It also blocks U.S. funds channeled through United Nations entities in Gaza unless the President certifies those entities aren't promoting anti-Israel or anti-Semitic content. The certification requirements apply to all federal funding, including aid delivered via international organizations. This directly affects U.S. foreign aid programs operating in Gaza by imposing new conditions before funds can be used.
