Kennedy was formerly an
assistant district attorney in the
Philadelphia DA's Office, where he prosecuted felonies Kennedy later returned to the East Coast to lead the Watershed Institute at
Boston College, and was chairman of the re-election campaign of his uncle,
U.S. Senator Ted Kennedy, in 2000. Kennedy never declared his candidacy, citing his desire to spend time with his family, including his three children under the age of 10. Kennedy wrote ''Danger's Hour: The Story of the USS Bunker Hill and the Kamikaze Pilot Who Crippled Her
, which was released by Simon & Schuster in 2008. The book examines the story of the Essex
-class aircraft carrier USS Bunker Hill
during the Japanese naval assault of May 1945, in the final chapters of the Second World War. Kirkus Reviews'' said of the book that Kennedy "describes that attack and its aftermath in scarifying detail that is not for the squeamish" and assessed it as "useful to students of the last months of the
Pacific War, though less so than" preceding works on the
kamikaze by
Emiko Ohnuki-Tierney and David Sears. Kennedy endorsed Senator
Barack Obama in the
2008 Democratic presidential primaries, and campaigned for him. In June 2008, Kennedy introduced Obama at a dinner at
Hickory Hill, the
McLean, Virginia homestead of his mother, Ethel Kennedy. In October 2009, Kennedy endorsed
Alan Khazei in the
January 2010 special election to fill the U.S. Senate seat of his late uncle, Ted Kennedy. Kennedy was nominated by President Obama to serve as a member of the Board of the Directors of the
Overseas Private Investment Corporation (OPIC), and the Senate confirmed him by
voice vote in October 2011. He served as a board member from 2011 until January 2018. In 2004, along with his mother and siblings, Kennedy supported the demolition of the
Ambassador Hotel in Los Angeles (the site of his father's 1968 murder) in order to make way for a
new public school complex. Kennedy said that a school was "a fitting memorial" for his father and that no part of the hotel site should be retained as a memorial, writing, "The Ambassador Hotel has nothing to do with who my father was or what he tried to do with his life." In 2021, after his father's assassin,
Sirhan Sirhan, was recommended for parole, Kennedy was one of six surviving Kennedy children to oppose the proposed release; two other surviving children supported parole for Sirhan. ==Personal life==
