Rep. Marjorie Taylor Greene (R-GA) said the U.S. should not fund Israel's "genocide" against Gaza and rather focus on an "America First" agenda ahead of the Sept. 30 government funding deadline.

Greene's remarks signal a rare challenge from the right to Republican unity on Israel, deepening tensions over U.S. foreign policy.

Georgia U.S. Rep. Marjorie Taylor Greene became the first congressional Republican to use the word “genocide” to refer to Israel’s actions in Gaza Monday, and a Democratic member of the Georgia delegation followed suit Tuesday.

Prime Minister Keir Starmer said his government would act unless there was a truce, citing the “intolerable” humanitarian crisis in Gaza.

Pressure to formally recognize Palestinian statehood has mounted since French President Emmanuel Macron announced that his country will become the first major Western power to recognize a Palestinian state in September.
