The White House is in the early stages of talks to fulfill President Donald Trump's pledge to move the US embassy in Israel from Tel Aviv to Jerusalem.
Spokesman Sean Spicer said: "We are at the very beginning stages of even discussing this subject."
Washington's embassy is in Tel Aviv, as are most foreign diplomatic posts.
Israel calls Jerusalem its eternal capital, but Palestinians also lay claim to the city as part of an eventual Palestinian state.
Both sides cite biblical, historical and political claims.
A move would likely spark anger in the Arab world.
All weekend it felt as though the new administration had a self-destruct button and was desperately searching for it.
White House press secretary Sean Spicer appears to be enraged that the press told the truth about the size of the Trump inauguration crowd.
White House press secretary Sean Spicer said the inauguration crowd had been 'the largest audience to ever witness an inauguration, period'.
