Theodore Roosevelt IV

Theodore Roosevelt V (born November 27, 1942), also called Theodore IV, is an American investment banker and managing director at Barclays Investment Bank. He is a member of the Council on Foreign Relations, the Economic Club of New York, and the Foreign Policy Association, and serves on the Advisory Council of Represent.Us, a nonpartisan anti-corruption organization. Roosevelt is also a prominent conservationist. His name suffix varies since his great-grandfather, President Theodore Roosevelt, was a son of Theodore Roosevelt Sr., though the same-named son did not commonly use a "Jr." name suffix.

Early years
Theodore Roosevelt V was born on November 27, 1942. He is the only son of Theodore Roosevelt IV (1914–2001) and Anne Mason Babcock (1917–2001).

In 1972, Roosevelt earned an MBA from the Harvard Business School, where he was a member of the HBS Rugby Club.

Roosevelt is a great-grandson of President Theodore Roosevelt. As an Oyster Bay Roosevelt, and through his ancestor Cornelius Van Schaack Jr., he is a descendant of the Schuyler family. His maternal grandparents were George Wheeler Babcock (1879—1950) and Anne Mason Bonnycastle Robinson (1886—1923).

After college, he was commissioned as an ensign in the U.S. Naval Reserve on June 16, 1965, and served as a U.S. Navy officer with Underwater Demolition Team 11 (BUD/S Class 36). After completing BUDS he served for two years in Vietnam with the Navy SEALs. He remained in the Naval Reserve after leaving active duty and was promoted to lieutenant commander on April 1, 1974.

He would later then go onto serving in the U.S. State Department as a foreign service officer in Washington, D.C. and the Upper Volta.

On April 18, 2016, the day before the New York Republican primary, Roosevelt endorsed Ohio Governor John Kasich for president of the United States.

Roosevelt suggested on Twitter that Donald Trump was the "loser" following a report in The Atlantic that Trump chose not to visit an American military cemetery in France, with Trump allegedly saying "Why should I go to that cemetery? It's filled with losers."
