Former Vice President Dick Cheney, considered by many political observers to be the most politically active and influential vice president in U.S. history, has died.
“Richard B. Cheney, the 46th Vice President of the United States, died last night, November 3, 2025,” his family said in a statement. “He was 84 years old. His beloved wife of 61 years, Lynne, his daughters, Liz and Mary, and other family members were with him as he passed. The former Vice President died due to complications of pneumonia and cardiac and vascular disease.”
He worked for nearly four decades in Washington. He served as the youngest White House chief of staff under President Gerald Ford; represented Wyoming in the U.S. House of Representatives — where he worked with congressional leadership and President Ronald Reagan; was secretary of defense under President George H.W. Bush; and later served two terms as vice president under Bush’s son, President George W. Bush.

He was also CEO of Halliburton, an energy company based in Texas that had a global presence.
When terrorists attacked the United States on Sept. 11, 2001, it was Cheney who first took charge while the president was out of Washington.
“When the president came on the line, I told him that the Pentagon had been hit and urged him to stay away from Washington,” Cheney recalled in his memoir, “In My Time.” “The city was under attack, and the White House was a target. I understood that he didn’t want to appear to be on the run, but he shouldn’t be here until we knew more about what was going on.”
He and senior staff gathered at the Presidential Emergency Operations Center, where they monitored the horror unfolding.

“I stayed up into the morning hours thinking about what the attack meant and how we should respond,” Cheney wrote in his memoir. “We were in a new era and needed an entirely new strategy to keep America secure. The first war of the twenty-first century wouldn’t simply be a conflict of nation against nation, army against army. It would be first and foremost a war against terrorists who operated in the shadows, feared no deterrent, and would use any weapon they could get their hands on to destroy us.”
As vice president, Cheney was also known as the mastermind behind much of the Bush administration’s strategy in Iraq.
“His power is unparalleled in the history of the republic, frankly, for that position,” John Hulsman, a research fellow at The Heritage Foundation, a conservative Washington-based think tank, told ABC’s “Nightline” in 2005.
