The U.S. delegation planned to meet regional leaders to discuss a "path to substantive Israeli-Palestinian peace talks", a White House official said at the time.
In a recent speech at a rally in Tel Aviv, Netanyahu attacked the Oslo Accords, the interim Israeli-Palestinian agreement meant to facilitate a solution to end the Israeli-Palestinian conflict.
Palestinians were still seeking a pledge of support from the Trump administration for the creation of a Palestinian state alongside Israel - the foundation of US Middle East policy for the past two decades.
In a statement, the prime minister said he and the visiting U.S. delegation "discussed ways to promote peace and prosperity in the region".
Kushner was charged with helping to broker a deal between Israelis and Palestinians after Trump took office.
Palestinians walk next to Israeli forces at the entrance of the al-Aqsa Mosque compound in Jerusalem al-Quds' Old City on July 25, 2017. In an op-ed entitled "The never-ending peace process farce", Liebler says Abbas real goal is the destruction of the Jewish state.
Trump's domestic troubles, including his response to demonstrations by white supremacists and neo-Nazis in Charlottesville, Virginia, have weakened his ability to demand compromise from Israelis and Palestinians, said Jonathan Rynhold, a researcher at the Begin-Sadat Center for Strategic Studies at Bar-Ilan University near Tel Aviv.
"I do not think the American envoys are coming carrying anything - nothing at all", he told reporters.
After initially welcoming the election of Trump, the Palestinians have expressed increasing frustration with what they say is a failure by the USA president to offer a clear vision for peace.
Jibril Rajoub, a senior member of Abbas's Fatah party, said they would be demanding a clear commitment from Kushner and Greenblatt to an independent Palestinian state.
"Abbas is coming to the end of his reign". But he has since given few details of his vision for peace, managing to frustrate both sides. "That's the best view as to not really bias one side over the other, to make sure that they can work through it". "Since the Trump administration came to power, we've seen the advancement of thousands of housing units through plans and tenders".
"It is time for President Trump to pay serious attention to the establishment of a Palestinian state". And Netanyahu did have some polite remarks at the start of that meeting.
"That kind of leverage has a very short shelf life if it's not used", warns Daniel Shapiro, the former US Ambassador to Israel under Barack Obama.
Shapiro said the U.S. should "recalibrate" the United States team's efforts from striking a peace deal to Palestinian institution building and economic development to prepare the Palestinians for future statehood. "They all come in thinking they'll be the ones to solve this, and then they find out how hard it really is".
