JERUSALEM — Prime Minister Benjamin Netanyahu is scheduled to land Monday in a Washington consumed by political turmoil, creating further uncertainty about U.S.-Israeli relations at a crucial moment in the Gaza war.

       President Biden — who announced the end of his reelection bid on the eve of Netanyahu’s departure — has both championed Israel’s right to wage war against Hamas and chided the prime minister for his management of the conflict. Israeli officials didn’t confirm that the prime minister would meet with the president as planned until the day before takeoff; they now don’t know what the dramatic campaign upheaval will mean for the future.
