Former U.S. Vice President Dick Cheney has died at the age of 84. Richard B. Cheney, who served as the 46th U.S. Vice President under President George W. Bush, passed away on Monday night due to complications of pneumonia and cardiac and vascular disease. Cheney's wife of 61 years, Lynne, and his daughters, Liz and Mary, were with him when he died, according to a statement from the family. "Dick Cheney was a great and good man who taught his children and grandchildren to love our country, and to live lives of courage, honour, love, kindness, and fly fishing," they said. "We are grateful beyond measure for all Dick Cheney did for our country. And we are blessed beyond measure to have loved and been loved by this noble giant of a man." Cheney served as Vice President between 2001 and 2009. He played a key role in Bush's "war on terror" and the invasion of Iraq following the 9/11 attacks in 2001. The businessman and politician also served as the White House Chief of Staff under Gerald Ford in the 1970s, and Secretary of Defense under George H.W. Bush between 1989 and 1993. He was also the U.S. representative for Wyoming between 1979 to 1989. After all his years in the Republican Party, Cheney sparked controversy last year when he announced he would vote for Democrat Kamala Harris in the presidential election instead of Donald Trump.
