President Trump is scheduled to speak to leaders in Jordan, the Palestinian Authority and Israel on Tuesday, the White House said, amid speculation that Trump could soon change the U.S. policy toward Jerusalem.

Trump missed a deadline this week to extend a waiver that would leave the American embassy at its current location in Tel Aviv or move the embassy to Jerusalem. Although relocating the embassy to Jerusalem would fulfill one of Trump's campaign promises, the move could ignite tensions in the region because it would signal that the U.S. formally recognizes Jerusalem as the capital of Israel.

Palestinian Authority leaders have warned in recent days that peace talks could fall apart if the Trump administration decides against issuing a waiver that would keep the U.S. embassy in Tel Aviv.

Trump will speak to Israeli Prime Minister Benjamin Netanyahu, Jordanian King Abdullah and Palestinian Authority President Mahmoud Abbas on Tuesday, the White House said.

"There are likely other foreign leader calls that will take place today," a White House spokesman said in a statement.

Deputy press secretary Hogan Gidley told reporters traveling aboard Air Force One on Monday that the president still plans to move the embassy to Jerusalem, but noted that he hasn't yet decided whether the relocation will take place immediately or after another six-month waiver period. The president has already issued one such waiver this year.

"The president has been clear on this issue from the get-go — that it's not a matter of if, but a matter of when," Gidley said.
