Aides say the president has no plans ever to serve as an “arbiter of details” in future peace negotiations. But “he has expressed a general concern” with ongoing Israeli settlement activity, the official said.

“He will reiterate that,” said the official. “He has not abandoned the two-state solution.”

Trump first outlined his concerns about Israel’s settlement construction outside of existing settlement blocs in February when Prime Minister Benjamin Netanyahu visited him in Washington. “Hold back a bit” on future building, Trump asked Netanyahu in front of the press.

Now, Trump expects “assurances and signals from the Israeli government that they’ve heard his views,” the senior official said.
