Colin Powell remembered as statesman and reluctant warrior at Friday funeral

Retired Gen. Colin Powell, the first African American to serve as chairman of the Joint Chiefs of Staff, and later as the first Black secretary of state, was remembered and celebrated as a statesman, a warrior and a trailblazer Friday at the Washington National Cathedral.

While attendance was by invitation only, the private service began at noon and was nationally televised. ABC News and ABC News Live presented special coverage.

Powell died last month at 84 from complications of COVID-19. Though he was fully vaccinated, his immune system was comprised from cancer treatments, his spokesperson said.

"It's really hard to overstate the respect Colin Powell had," said ABC News Chief Global Affairs Correspondent Martha Raddatz, who covered Powell's career for decades. "When traveling around the world with him, it was almost like traveling with a king -- but Colin Powell, of course, never acted like one."

President Joe Biden, former President Barack Obama and former President George W. Bush, as well as former Secretary of State Hillary Clinton, were in attendance. Former President Bill Clinton, who was recently hospitalized with an infection, will not attend, an aide saying, "Under any other circumstances, he would have been there, but he's taking the advice of his doctors to rest and not travel for a month very seriously. So Secretary Clinton will be there representing them."

The iconic cathedral is where four presidents have had funeral services: Dwight D. Eisenhower, Gerald Ford, Ronald Reagan and George H. W. Bush.

Tributes were given by former Secretary of State Madeleine Albright and former Deputy Secretary of State Richard Armitage, as well as Powell's son, Michael.

"He made pragmatism charismatic," Albright said. "Beneath that glossy exterior of Warrior Statesman was one of the gentlest and most decent people any of us will ever meet."

Armitage, in his tribute, recalled a time when Powell sang all of "Mamma Mia" to a "very amused foreign minister from Sweden and to a gobsmacked U.S. delegation -- who'd never seen anything like it." Earlier, the U.S. Army Brass Quintet played ABBA's "Dancing Queen" -- one of Powell's favorites.

Powell's son Michael delivered an emotional eulogy, talking through tears, about how one of his most powerful memories comes from his father holding his hand when he was young -- and then holding his father's hand as he lay dying at Walter Reed National Military Medical Center.

"We walk through this life holding hands with the ones we love. They guide us. They pull us out of harm's way. They touch and caress us with love and kindness. One of my most powerful memories comes from holding my dad's hand," Powell said.

"That hand is still now, but it left a deep imprint on the lives of family and dear friends, soldiers and sailors, presidents and prime ministers and a generation of aspiring young people," he said of his father.

Powell broke barriers serving under four presidents -- Reagan, Bush, Bill Clinton and George W. Bush -- at the very top of the national security establishment, first as deputy national security adviser and then as national security adviser. Later, he was nominated to be chairman of the Joint Chiefs of Staff, the senior ranking member of the U.S. armed forces and top military adviser to the president, and after that, secretary of state -- the first African American to hold both posts.

As secretary of state, it was Powell who told the world that Iraq's Saddam Hussein had weapons of mass destruction and posed an imminent threat, assertions that later proved to be false. He told ABC News' Barbara Walters in Sept. 2005 that he felt "terrible" about the claims he made in a now-infamous address to the U.N. Security Council arguing for a U.S. invasion.

When asked if he feels it has tarnished his reputation, he said, "Of course it will. It's a blot. I'm the one who presented it on behalf of the United States to the world, and [it] will always be a part of my record. It was painful. It's painful now."

"To be that example of someone who admitted mistakes," Raddatz said. "What an example for today's youth -- not only to have someone who rose to such a powerful position -- but who looked at himself and reflected on what he had done right and what he had done wrong."

Throughout his 35-years of service in the military, Powell, a decorated war hero who deployed twice to Vietnam, never made his political leanings known. Although he served under both Democratic and Republican administrations, it wasn't until 1995 that Powell announced that he had registered as a Republican. He formally supported the candidacy of Democratic presidential candidates Lyndon Johnson, Barack Obama, Hillary Clinton and Biden.

The reelection campaign of former President Donald Trump brought out Powell's political side in the last years of his life, when he called on voters not to support the incumbent, Republican president, calling him dangerous to democracy.

In many ways, Powell, the son of Jamaican immigrants who grew up in the Bronx, was the embodiment of the American Dream. He left behind his wife, Alma Powell, and his three children, Michael, Linda and Annemarie.

In a statement Oct. 18 announcing his death, his family said, "We have lost a remarkable and loving husband, father, grandfather and a great American."

ABC News and ABC News Live will present special coverage of the memorial service beginning at approximately noon EDT.
