The Senate on Monday passed a resolution calling on President Trump to “abide by” provision of a 1995 law moving the U.S. Embassy in Israel from Tel Aviv to Jerusalem.

The provision was passed as part of a measure commemorating the 50th anniversary of the reunification of Jerusalem, which followed the Six Day War in 1967.

The Senate passed it in a 90-0 vote.

Trump promised during his campaign that he would move the U.S. Embassy to Jerusalem, but in a reversal, signed an order on June 1 keeping the embassy in Tel Aviv, at least for now. The White House said it delayed the move to improve the chances of reaching a peace deal between Israel and the Palestinian Authority.

The 1995 law called for the president to move the embassy to Jerusalem by May 31, 1999, or else issue a waiver every six months.

Senate Majority Leader Mitch McConnell did not mention the embassy in a Monday floor speech calling for support of the resolution.
