Dick Cheney, a driving force behind the US invasion of Iraq in 2003 who was considered by presidential historians as one of the most powerful vice presidents in US history has died at age 84, his family said in a statement on Tuesday.
Cheney died Monday night from complications of pneumonia and cardiac and vascular disease, his family said.
The Republican - a former Wyoming congressman and secretary of defence - was already a major Washington player when then-Texas governor George W Bush chose him to be his running mate in the 2000 presidential race that Bush went on to win.
As vice president from 2001 to 2009, Cheney fought vigorously for an expansion of the power of the presidency, having felt that it had been eroding since the Watergate scandal that drove his one-time boss Richard Nixon from office. He also expanded the clout of the vice president's office by putting together a national security team that often served as a power centre of its own within the administration.
His daughter Liz Cheney also became an influential Republican lawmaker, serving in the House of Representatives but losing her seat after opposing Republican President Donald Trump and voting to impeach him in the wake of the January 6, 2021 attack on the Capitol by his supporters.
Cheney was troubled much of his life by heart problems, suffering the first of a number of heart attacks at age 37. He had a heart transplant in 2012.
