From 1970 to 1973 , he was the principal assistant to Caspar W .

Taft was then appointed Deputy Secretary of Defense and served from January 1984 to April 1989 . He served as acting Secretary of Defense from January to March 1989 after George H . W . Bush became president . Bush ' s initial nominee , John Tower , was not confirmed by the United States Senate after much contentious debate and testimony . The eventual appointee confirmed in March was Richard B . Cheney ( later Vice President of the United States , 2001 – 2009 ) . Although he was only acting Secretary of Defense , and never confirmed as the permanent Secretary , he became the third member of his family to hold a position as civilian head of a military department , following his great - great - grandfather Alphonso Taft ( under President Ulysses S .

After the election of 2000 , George W . Bush appointed Taft to serve as chief legal advisor to the United States Department of State under Secretary of State Colin Powell , with whom he was reportedly friends . This appointment was technically a significantly lower appointment than he had held in other administrations , but it permitted him to work with his wife , Julia Taft , a top State Department official in charge of refugees who also served during the Clinton administration . In 2004 , Taft ' s name surfaced as a dissenter concerning the policy of interrogation techniques for military detainees . In a January 11 , 2002 , memo , Taft opposed Department of Justice lawyers to argue that the president could not " suspend " U . S . obligations to respect the Geneva Conventions and that a legal argument to do so was " legally flawed and procedurally impossible . " This was also the position of Secretary of State Colin L . Powell , who attempted to persuade Bush to reconsider . Alberto R . Gonzales , the White House counsel , subsequently advised Bush in a memo that Taft and Powell were wrong and the Justice Department ' s analysis was " definitive . " Gonzales claimed terrorist attacks " require a new approach in our actions toward captured terrorists , " and argued that if suspected terrorists had never respected the Geneva Conventions ' human rights protections , the U . S . didn ' t need to do so . Leaving government service . After the re - election of President Bush , resignation of Colin Powell and appointment of Condoleezza Rice as secretary of state , Taft resigned to return to private practice , again at Fried , Frank , Harris , Shriver & Jacobson .

In January 2009 he was named chair of the board of trustees for Freedom House , an independent watchdog organization that supports the expansion of freedom around the world . On September 12 , 2006 , Taft co - signed ( along with 28 other retired military or defense department officials ) a letter to the chairman and ranking member of the Senate Armed Services committee in which he stated his belief that the Bush Administration ' s attempt to redefine Common Article 3 of the Geneva Convention " poses a grave threat " to U . S . service members . Taft is said to be one of the sources who told journalists David Corn and Michael Isikoff that former Deputy Secretary of State Richard Armitage was the source syndicated columnist Robert Novak had when he made public the fact that Valerie Wilson worked for the CIA . In a review of Corn ' s and Isikoff ' s book , " Hubris : The Inside Story of Spin , Scandal , and the Selling of the Iraq War " , Novak wrote : " I don ' t know precisely how Isikoff flushed out Armitage [ as Novak ' s original source ] , but " Hubris " clearly points to two sources : Washington lobbyist Kenneth Duberstein , Armitage ' s political adviser , and William Taft IV , who was the State Department legal adviser when Armitage was deputy secretary .
