WASHINGTON (AP) - Colin Powell, who served Democratic and Republican presidents in war and peace but whose sterling reputation was forever stained when he went before the U.N. and made faulty claims to justify the U.S. war in Iraq, has died of COVID-19 complications. He was 84.

A veteran of the Vietnam War, Powell rose to the rank of four-star general and in 1989 became the first black chairman of the Joint Chiefs of Staff. In that role he oversaw the U.S. invasion of Panama and later the U.S. invasion of Kuwait to oust the Iraqi army in 1991.

But his legacy was forever marred when, in 2003, he went before the U.N. Security Council as secretary of state and made the case for U.S. war against Iraq. He cited faulty information claiming Saddam Hussein had secretly stashed away weapons of mass destruction. Iraq’s claims that it had no such weapons represented “a web of lies,” he told the world body.

In an announcement on social media, Powell’s family said he had been fully vaccinated.

“We have lost a remarkable and loving husband, father and grandfather and a great American,” the family said. Powell had been treated at Walter Reed National Medical Center in Bethesda, Maryland.

Powell was the first American official to publicly lay the blame for the 9/11 terrorist attacks on Osama bin Laden’s al-Qaida network and made a lightning trip to Pakistan in October 2001 to demand that then-Pakistani President Pervez Musharraf cooperate with the United States in going after the Afghanistan-based group, which also had a presence in Pakistan, where bin Laden was later killed.

As President George W. Bush’s first secretary of state, Powell led a State Department that was dubious of the military and intelligence communities’ conviction that Saddam Hussein possessed or was developing weapons of mass destruction. And yet, despite his reservations, he presented the administration’s case that Saddam indeed posed a major regional and global threat in a speech to the U.N. Security Council in the run-up to the war.

Powell rose from a childhood in a fraying New York neighborhood to become the nation’s chief diplomat. “Mine is the story of a black kid of no early promise from an immigrant family of limited means who was raised in the South Bronx,” he wrote in his 1995 autobiography “My American Journey.”

At City College, Powell discovered the ROTC. When he put on his first uniform, “I liked what I saw,” he wrote.

He joined the Army and in 1962 he was one of more than 16,000 “advisers” sent to South Vietnam.
