Katherine Clark, the No. 2 House Democrat, voted for an amendment to cut off military aid to Israel on July 16, 2026 — marking a significant break from Democratic leadership under Hakeem Jeffries. Over 100 House Democrats voted for the amendment, which failed to pass, but exposed a sharp generational and ideological split within the party on U.S. support for Israel. This vote underscores how Palestinian rights and humanitarian concerns have become mainstream positions within the Democratic caucus, reshaping foreign policy debates that were once consensus issues.
