U.S. Secretary of State Mike Pompeo declined on Wednesday to publicly say the Trump administration still backs a two-state solution to the conflict between Israel and the Palestinians.
"We are now working with many parties to share what our vision [is] as to how to solve this problem," Pompeo told a U.S. Senate hearing where he was pressed for a response on the issue.
He said the administration "has been working on a set of ideas" for Middle East peace "that we hope to present before too long," adding that he hoped they would provide a basis for discussions on resolving the Israeli-Palestinian conflict.
Democratic Senator Tim Kaine asked Pompeo, a former Republican member of the House of Representatives, if he thought a peace agreement including one state for Israel and one state for the Palestinians was an outdated idea.
"It's certainly an idea that's been around a long time, senator," Pompeo responded.
"Ultimately the individuals in the region will sort this out," the secretary of state said.
Prime Minister Benjamin Netanyahu secured a clear path to re-election on Wednesday, and a record fifth term in office, with religious-rightist parties set to hand him a parliamentary majority, despite a close contest against his main centrist rival, Benny Gantz.
In a rare turn during the campaign toward the Israeli-Palestinian conflict, Netanyahu alarmed Palestinians by pledging to annex Jewish settlements in the West Bank if re-elected.
That came after Trump signed a proclamation during Netanyahu's visit to Washington on March 25, officially granting U.S. recognition of the Golan Heights as Israeli territory, a dramatic departure from decades of American policy.
The move, which Trump announced in a tweet days prior, was widely seen as an attempt to boost Netanyahu as he ran for re-election on April 9.
The Trump administration has been promising for many months that it would roll out a Middle East peace plan after Israel's election.
