Passage: The Embassy opened at its Jerusalem location on May 14, 2018, the 70th anniversary of the creation of the modern State of Israel. It was relocated from its previous site in Tel Aviv by the Donald Trump Administration and is situated in the Arnona section of the US Consulate. The opening prayer was delivered by the Evangelical Reverend Robert Jeffress, and the closing prayer was given by the Evangelical Reverend John C. Hagee.The move came 23 years after the passage of the Jerusalem Embassy Act of October 23, 1995, which set a deadline of May 31, 1999, for the move. The Clinton, Bush, and Obama administrations had all deferred the move. Eugene Kontorovich claimed that the decision to shift the US embassy to this area is tantamount to the United States recognizing Israeli sovereignty over land that it captured in the Six-Day War in 1967.However, despite the move of the Embassy to Jerusalem, President Trump signed on June 4, 2018 an executive order postponing the move of the Embassy to Jerusalem, although it already moved to that city. He was required to sign the order since the Jerusalem Embassy Act requires the US Ambassador to have a permanent residence in Jerusalem, a condition not yet fulfilled.

Question: Which presidential administrations deferred a move?
