Palestinian Authority President Mahmoud Abbas told a group of Israeli lawmakers and activists Sunday that U.S. President Donald Trump’s negotiating team had asked whether he would agree to a confederation with neighboring Jordan, Bloomberg reported.

Peace Now’s executive director Shaqued Morag, who attended the meeting, said Abbas told the U.S. that he would agree to a trilateral confederation that includes Israel. Decades ago, Israeli officials mooted the notion of a confederation between the Palestinians and Jordan, but not one that would include Israel. Israeli government spokesmen couldn’t immediately be reached for comment.

A statement from Abbas’s office said the president emphasized in the meeting that “peace must be reached no matter how great the challenges and difficulties it faces.” The statement didn’t mention a confederation proposal. Mohammed al Madani, head of communication with the Israeli society, declined to elaborate.
