On his return he was appointed chief of the newly created Alien Enemy Control Section of the State Department. The Alien Enemy Control Section was unpopular and short-lived. Bingham got off the boat before it sank, resuming the practice of law in New York City in 1946. He left the practice of law again in 1951 to become assistant director of the Office of International Security Affairs. Bingham left in the same year to become deputy administrator of the Technical Cooperation Administration, implementing the Point 4 Program of technical assistance to developing countries. His book, Shirt-Sleeve Diplomacy: Point 4 in Action, was published in 1953. He left the administration in that year and resumed the practice of law. In 1955 he became secretary to fellow Bonesman, W. Averell Harriman, while he was Governor of New York. When Harriman was defeated in the 1958 election by Nelson Aldrich Rockefeller, Bingham joined the law firm Goldwater & Flynn. In 1961 Bingham entered the world of diplomacy, as a United States representative on the United Nations Trusteeship Council with rank of Minister in 1961 and 1962, serving as President in 1962. During this period he was also principal adviser to the U.S. ambassador to U.N. on colonial and trusteeship questions. From 1963 to 1964 he was a United States representative on the United Nations Economic and Social Council with rank of Ambassador. He was also alternate representative to the 15th and 18th United Nations General Assemblies.
Congress
In 1964 he was elected to the House of Representatives from the 23rd District of New York, a district in the Bronx, at a time when elections in the Bronx were decided in the Democratic primaries in contests between "regular" or machine Democrats, and "reform" or challenger Democrats. Bingham defeated Charles Buckley, the leader of the Bronx "regular" Democrats and a powerful, senior committee chairman in Congress, in a rematch following Bingham's defeat in his first try against the incumbent Buckley in the 1962 Democratic primary. Bingham represented the 23rd District from January 3, 1965 until January 3, 1973, when, as a result of redistricting following the 1970 census, he was elected to the House from the 22nd District of New York following a bruising primary with neighboring Democratic incumbent congressman James H. Scheuer. He served the 22nd District from January 3, 1973 until January 3, 1983, but did not pursue reelection when, in 1982, his district essentially disappeared as a result of another post-census redistricting. In the House, Bingham served on the Foreign Affairs Committee and the Interior and Insular Affairs Committee and chaired the Subcommittee on International Economic Policy and Trade. He was particularly dedicated to nuclear non-proliferation and environmental protection. Bingham was instrumental in supporting aid to Romania following the Vrancea earthquake in March 1977, sponsoring a bill to provide $20 million in assistance to the country.
Family
He was married to June Rossbach, an author, playwright, and member of the Lehman family. They had four children: Sherrell Bingham Downes; Timothy Woodbridge Bingham; Claudia Bingham Meyers; and June Mitchell Esselstyn. After Jonathan Bingham's death, Mrs. Bingham married Robert Birge and was then known as June Bingham Birge.
Death
Bingham died from complications of pneumonia, aged 72, at the Presbyterian Hospital in Manhattan on July 3, 1986. He was interred in Woodbridge Cemetery, in Salem, New London, Connecticut.
