Former US Vice President Dick Cheney has died at the age of 84, CNN reports.

Cheney served in the administrations of four US presidents. From 1989 to 1993, he served as US Secretary of Defense. From 2001 to 2009, he served two terms as Vice President of the United States in the administration of George W. Bush.
CNN describes Republican Cheney as "the most powerful vice president in modern America" and the "chief architect of the war on terror" who played a key role in the US invasion of Iraq.
In the last years of his life, Cheney, while remaining a staunch conservative, was ostracized in the Republican Party due to his harsh criticism of Donald Trump, whom he called a “coward” and “the greatest threat to the Republic in history,” writes CNN.
Cheney had regular cardiovascular problems for decades and suffered several heart attacks. In 2012, Cheney underwent a heart transplant.
