Breaking one of his key campaign promises, on June 1, 2017 President Trump released a statement aknowledging that he was going to, like the three Presidents before him, sign a waiver postponing the move of the U.S. embassy in Tel Aviv to Jerusalem. Please find the official statement released by the White House below.
While President Donald J. Trump signed the waiver under the Jerusalem Embassy Act and delayed moving the U.S. Embassy in Israel from Tel Aviv to Jerusalem, no one should consider this step to be in any way a retreat from the President's strong support for Israel and for the United States-Israel alliance. President Trump made this decision to maximize the chances of successfully negotiating a deal between Israel and the Palestinians, fulfilling his solemn obligation to defend America's national security interests. But, as he has repeatedly stated his intention to move the embassy, the question is not if that move happens, but only when.
