The Senate overwhelmingly rejected a resolution to ban certain arm sales to Israel late Wednesday evening, exposing stark divisions among Democrats over support for Israel and the country’s war against Hamas in Gaza.

In a sign of mounting apprehension over Israel ’s war in Gaza, a majority of Senate Democrats voted in favor of resolutions to block U.S. weapons sales to Israel on Wednesday. Despite this growing support, the measures failed by wide margins in the Republican-controlled chamber.

Supporters of Palestinian rights say although bill to block arms to Israel failed to pass, vote shows ‘shift’ on issue.
