A US official said Mr. Trump wants to know both Mr. Netanyahu and Mr. Gantz are on board with the plan before announcing it.
Netanyahu went on to say that "over the past three years I have had countless conversations with President Trump, a great friend of the State of Israel, and with his staff, about Israel's vital interests, about our security and about our righteousness".
"The president's peace plan is a significant and historic milestone, indeed", Gantz told reporters after his meeting with Trump.
Erekat also warned that the plan virtually assures that Israel will ultimately have to absorb the Palestinians, and give them the vote inside Israel. They do not have passports but only laissez-passer certificates that are rejected for travel purposes by most states.
"I am leaving for Washington with a sense of great mission, great responsibility and great opportunity, and I am full of hope that we will be able to make history", he concluded. The Palestinians, claiming the White House is unfairly biased toward Israel, have already said they won't accept the plan.
Reports in Israeli media have speculated Trump's plan could include the possible annexation of large pieces of territory that the Palestinians seek for a future independent state.
In recent days, the Israeli defense establishment has held multiple security assessments regarding the implications of the US plan's release. Israel's PM Benjamin Netanyahu is already in DC, but no Palestinian envoy is present.

China also canceled scheduled tariffs . "We encourage the administration to stay at the negotiating table until the U.S". As part of the deal, China will buy 40-50 billion dollars' worth of agriculture goods over the next two years.
These included recognising Jerusalem as the capital of Israel, moving the US Embassy from Tel Aviv to Jerusalem and slashing hundreds of millions of dollars in humanitarian aid to the Palestinians.
The Palestinian leadership said that there had been no communication with the Trump administration.
Shapiro, who served during the Obama administration and continues to live in Israel, said that the Trump plan represents a major shift from previous peace proposals, and "veers away from the model of two states for two people in a negotiated settlement". The Palestinians have not been consulted on the much-trumpeted deal and have pre-emptively rejected the USA proposal.
In weekend consultations with his advisers, Gantz apparently decided he would meet with Trump, but only in a private meeting on Monday, after which he plans to return to Israel immediately to lead the parliamentary hearing on Tuesday seeking to reject Netanyahu's plea for immunity from Israeli lawmakers.
Anyway, the White House invitation, delivered Thursday by Vice President Mike Pence in Jerusalem, had put Mr. Gantz in trouble.
On Sunday, the Palestinian Authority's foreign ministry called for a "clear global declaration rejecting "the deal of the century", saying it would endanger regional stability.
Having both leaders present helps take the politics out of the effort, said a US source familiar with internal deliberations.
But it could give Mr Netanyahu, who is in the middle of his third re-election campaign in under a year, a boost as he tries to remain in office while fighting criminal charges of fraud, breach of trust and accepting bribes.
