Support for the “Block the Bombs Act,” a bill seeking partial restrictions on US arms transfers to Israel, has expanded significantly since its introduction by Congresswoman Delia Ramirez in June 2025. Initially backed by 21 Democratic lawmakers, the proposal now has 73 co-sponsors, marking what Palestinian rights advocates call a historic shift. Ramirez said the bill, once seen as extreme, has entered the mainstream debate. However, it remains far from a majority in the 435-member House of Representatives.

The bill would prohibit the transfer of certain heavy bombs and artillery shells used in Israel’s military operations in Gaza. It has gained bipartisan support, including from Republican Thomas Massie, and endorsement from the Congressional Progressive Caucus. Advocates such as Margaret Dirius of the Institute for Middle East Understanding and Rashida Tlaib argue that the growing support reflects changing public opinion and a demand for domestic investment over foreign military aid.

The bill’s anniversary coincides with other congressional moves questioning US-Israel relations, including votes to limit arms transfers and presidential war powers. Activists say the momentum signals rising awareness of humanitarian concerns in Gaza but acknowledge that congressional backing remains limited.
