Between 1951 and 1968, the United States had no official representative accredited to the Holy See. President Richard Nixon changed this when he appointed Henry Cabot Lodge Jr. as his personal representative. President Jimmy Carter followed with the appointment of former New York City mayor Robert F. Wagner Jr. Every ambassador to date has been a member of the Roman Catholic Church. The most recent ambassador was Joe Donnelly, who presented his credentials to Pope Francis on April 11, 2022.[3]
History before formal diplomatic relations established
The United States had diplomatic relations with the Papal States from 1797 to 1867. The Papal States ceased to exist in 1870, when its last territory (the city of Rome) was lost to the Kingdom of Italy. After that, the international status of the Papacy was controversial until 1929, when the Italian government agreed to the establishment of Vatican City as a sovereign city-state.
The United States was slow to establish full diplomatic relations with the re-established Holy See, partly due to the prevalence of anti-Catholicism in the United States. President Franklin D. Roosevelt's Postmaster General James Farley was the first high-ranking government official to normalize relations with the Holy See in 1933 when the Postmaster General set sail for Europe, along with Soviet Commissar of Foreign Affairs Maxim Litvinoff on the Italian Liner SS Conte di Savoia. In Italy Farley had an audience with Pope Pius XI, and dinner with Cardinal Pacelli, who was to accede to the papacy in 1939.[2]Myron Charles Taylor, an industrialist, philanthropist and diplomat (starting with World War II), served from December 1939 until 1950 as the personal representative of Presidents Franklin D. Roosevelt and Harry S. Truman to the Vatican.[4]
As no diplomatic relations with the Holy See were allowed by US law between 1867-1984, no Ambassadors were appointed during that period. However, some US Presidents appointed personal envoys to negotiate with the Vatican.
In 2009, the post of ambassador remained vacant for several months because of tensions between the Vatican and the Obama Administration over the issues of abortion and same-sex marriage.[7] Three candidates were mentioned, including Caroline Kennedy and Douglas Kmiec.[7][8][9]
From November 2012 through mid-2013, the seat was also vacant, after Miguel H. Díaz left the office to teach at the University of Dayton. President Barack Obama nominated Ken Hackett, a longtime president of Catholic Relief Services, for the position in June 2013.[10] Ken Hackett was confirmed by the U.S. Senate as U.S. Ambassador to the Holy See on August 1, 2013.[11][12]
