The Trump administration is moving faster than expected to transfer the American Embassy to Jerusalem from Tel Aviv by 2019, senior officials said Thursday, despite insisting last month that the move would not happen until the end of President Trump’s term.

The administration’s plans, following Mr. Trump’s recognition of Jerusalem as the capital of Israel, suggest it no longer cares about cushioning the blow of the new policy, which has drawn angry protests from Palestinians and other Arabs and cast Mr. Trump’s peacemaking ambitions into doubt.

Prime Minister Benjamin Netanyahu of Israel first broached the prospect of a faster move on Wednesday, telling reporters that the embassy would be moved “in the course of the year.” That put him at odds with Mr. Trump, who hours later said, “We’re not really looking at that.”

It was not clear whether Mr. Trump’s advisers had briefed him on the new timetable until Thursday. Officials said he was referring to the construction of an entirely new embassy compound in Jerusalem, which Secretary of State Rex W. Tillerson predicted would be completed “probably no earlier than three years out, and that’s pretty ambitious.”
