Differences remain between Israel and the US, following Prime Minister Benjamin Netanyahu's visit to Washington, the White House has said, BBC reported.
President Obama urged the Israeli PM to take steps to build confidence in the peace process, during "honest" talks on Tuesday, said spokesman Robert Gibbs.
Mr Gibbs also said the US was seeking "clarification" of the latest plans to build homes in occupied East Jerusalem.
Mr Netanyahu's trip came amid the worst crisis in US-Israeli ties for decades.
The Israeli prime minister delayed his departure from Washington on Wednesday to meet the US Middle East peace envoy, George Mitchell.
The spat flared two weeks ago when, during a visit by US Vice-President Joe Biden, Israel unveiled plans to build 1,600 homes in part of East Jerusalem, which Washington branded an insult.
Then, minutes before Mr Netanyahu's fence-mending visit to the White House on Tuesday, it emerged the Jerusalem municipal government had approved the building of 20 new apartments.
Mr Gibbs told reporters on Wednesday there were still areas of "disagreement" between the sides, following the two meetings in Washington, one of which was unscheduled.
He described the three-and-a-half hours of talks as an "honest and straightforward discussion that continues" about US-Israeli relations and peace efforts between Israel and the Palestinians.
"The president has asked the prime minister for certain things to build confidence up to proximity talks that we think can make progress," Mr Gibbs said, referring to the peace process.
He reiterated the US position that there is an "unbreakable bond" between America and the Israeli people.
The Israelis said there had been a "good atmosphere" during Tuesday's talks between Mr Netanyahu and Mr Obama.
But the BBC's Kim Ghattas in Washington notes the Israeli leader did not get the reception usually reserved for America's allies.
There was no press conference, no lavish welcome, and the White House did not even release a picture of the meeting.
It all signals that the US is playing tough, making clear it is upset with the Israeli government, says our correspondent.
