White House officials said Israel and Hamas were “closer now than we’ve been before” to reaching a ceasefire deal as Benjamin Netanyahu met Joe Biden on Thursday to discuss an end to the nine-month conflict in Gaza. The talks at the White House came amid unprecedented political turmoil in the US and domestic pressure on the Israeli prime minster to rescue the dozens of hostages still being held captive after Hamas’s 7 October attack. Netanyahu was also expected to meet the US vice-president, Kamala Harris, who is likely to replace Biden as the Democratic candidate for November’s election. “We’ve got a lot to talk about,” Biden said when he welcomed Netanyahu to the Oval Office. “From a proud Jewish Zionist to a proud Irish-American Zionist, I want to thank you for 50 years of public service and 50 years of support for the state of Israel,” Netanyahu told Biden at the start of their meeting. The president thanked Netanyahu and noted that his first meeting with an Israeli prime minister, Golda Meir, was in 1973, soon after he was elected to the Senate. Biden was expected to put pressure on Netanyahu to commit to at least the first stage of a three-part deal that would see some hostages released in exchange for a temporary ceasefire. A senior administration official said that a framework for the deal had been agreed upon but that “serious implementation issues … still had to be resolved. “I don’t expect the meeting to be a yes or no,” the official said. “It’s a kind of like, ‘How do we close these final gaps?’” At a press conference while the two leaders were meeting, the White House national security spokesperson, John Kirby, said gaps in the ceasefire deal could be overcome. “We need to get there soon,” he said. “We are closer now than we’ve been before. Both sides have to make compromises.” The State Department spokesperson, Matt Miller, said: “I think the message from the American side in that meeting will be that we need to get this deal over the line.” More than 39,000 Palestinian civilians have been killed in the conflict, and the international criminal court has issued an arrest warrant for Netanyahu for war crimes and crimes against humanity. The US does not recognise the court’s jurisdiction. Harris was expected to meet Netanyahu separately as she began her late campaign to challenge Donald Trump in November’s presidential vote. The vice-president must prove her mettle as a negotiator in one of the world’s most intractable conflicts. She has spoken forcefully about the need for a ceasefire and about the plight of Palestinian civilians in the conflict, and there is a possibility that she could win back some Democratic voters who believe that the Biden administration has done too little to end the conflict or limit sales of arms to Israel. Harris – the presiding officer of the Senate – did not attend Netanyahu’s address to a joint session of Congress on Wednesday but released a careful statement saying that her absence should not be interpreted as a boycott of the event. A senior administration official told the Associated Press there was “no daylight between the president and vice-president” on Israel. On Thursday, Harris issued a statement forcefully condemning pro-Palestine protesters who had demonstrated against Netanyahu’s speech in Washington. She said: “Yesterday, at Union Station in Washington DC we saw despicable acts by unpatriotic protesters and dangerous hate-fuelled rhetoric. “I condemn any individuals associating with the brutal terrorist organisation Hamas, which has vowed to annihilate the state of Israel and kill Jews. Pro-Hamas graffiti and rhetoric is abhorrent and we must not tolerate it in our nation.” The vice-president added: “I condemn the burning of the American flag. That flag is a symbol of our highest ideals as a nation and represents the promise of America. It should never be desecrated in that way. “I support the right to peacefully protest, but let’s be clear: antisemitism, hate and violence of any kind have no place in our nation.” Netanyahu is also scheduled to meet Trump on Friday at his residence in Mar-a-Lago. The two men have had a strained relationship since Netanyahu congratulated Biden on his victory in the 2020 elections, a vote that, Trump has claimed without evidence, was manipulated. Netanyahu promised “total victory” in the Gaza war in a raucous speech to a joint session of Congress on Wednesday, saying that there were “intensive” efforts to bring the hostages home but giving little detail about how that would be achieved. About 40 Democratic lawmakers – including the former House speaker Nancy Pelosi – boycotted the speech, and only half of congressional Democrats attended. “Benjamin Netanyahu’s presentation in the House Chamber today was by far the worst presentation of any foreign dignitary invited and honored with the privilege of addressing the Congress of the United States,” Pelosi wrote on X. Thousands protested on the streets of the capital, with both pro-Palestinian and pro-Israeli groups saying Netanyahu was using the conflict as cover for his own political problems at home. He did not mention the word “ceasefire” or the negotiations with Hamas once during the speech, instead he called for expedited deliveries of US arms to “help us finish the job faster”. “I will not rest until all their loved ones are home,” said Netanyahu during the speech. “All of them. As we speak, we’re actively engaged in intensive efforts to secure their release, and I’m confident that these efforts can succeed. Some of them are taking place right now. I want to thank President Biden for his tireless efforts on behalf of the hostages and for his efforts to the hostage families as well.” It is unclear whether Biden’s recent decision to end his presidential campaign will allow him to use greater leverage to convince Netanyahu to sign on to a deal. “The framework of the deal is basically there,” said a senior administration official. “There are some very serious implementation issues that still have to be resolved, and I don’t want to discount the difficulty of those … There are some things we need from Hamas, and there are some things we need from the Israeli side, and I think you’ll see that play out here over the course of the coming week.”
