President Donald Trump said that he is still deciding whether to move the Embassy of the United States in Israel from Tel Aviv to Jerusalem, suggesting he is open to abandoning a controversial campaign promise.

Im thinking about it. Im learning the issue and well see what happens, Trump told the Israeli newspaper Israel Hayom, Haaretz reported . Its not an easy decision. Its been discussed for so many years. No one wants to make this decision, and Im thinking about it seriously.

As a candidate, Trump repeatedly promised to recognize Jerusalem as Israels capital and move the U.S. embassy, including in a meeting with Israeli Prime Minister Benjamin Netanyahu in September.

Since his inauguration, however, Trump has been more equivocal on the matter.

Referring to the embassy move in an interview with Fox News Sean Hannity last month, Trump said, I dont want to talk about it yet. Its too early.

There is ample precedent for American presidents reneging on campaign promises to move the U.S. embassy to Jerusalem. Presidents Bill Clinton and George W. Bush both vowed to make the move, but decided in office that it would undermine peace negotiations between Israel and the Palestinians.

The international community largely views the Palestinian areas of East Jerusalem as occupied territory. Few countries recognize Jerusalem as Israels capital.

Although Israel maintains that Jerusalem is its capital, Palestinians living under Israeli occupation have long sought to make Jerusalem their capital as well, making it a key sticking point in Israeli-Palestinian peace negotiations.

Palestinian Authority President Mahmoud Abbas has warned Trump that moving the embassy would be disastrous. And Jordans King Abdullah told the House Foreign Affairs Committee that even Israeli intelligence officials are concerned about the implications of the decision, BuzzFeed News reported .

In the interview with Israel Hayom, Trump also indicated that he is critical of Israeli expansion of settlements in the occupied West Bank.

I want Israel to act reasonably in the peace process and that it will finally happen after so many years. And maybe there will even be a possibility of a bigger peace than just Israel and the Palestinians. I want both sides to act reasonably, and we have a good chance at that, Trump said.

There is limited remaining territory. Every time you take land for a settlement, less territory remains, he added. Im not someone who believes that advancing settlements is good for peace. But we are examining a number of options.
