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.

The Georgia Republican is the first in her caucus, which has generally rallied unconditionally around Israel, to use the word in reference to Gaza.

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