Colin Powell, the first Black secretary of State and one of the driving figures of the Iraq War, has died from complications from Covid-19, his family said on Facebook. Powell was 84.

“General Colin L. Powell, former U.S. Secretary of State and Chairman of the Joint Chiefs of Staff, passed away this morning due to complications from Covid 19,” the family wrote. “We have lost a remarkable and loving husband, father, grandfather and a great American,” they added.

Powell’s family noted that he was fully vaccinated.

Powell was still at risk despite being vaccinated because of both his advanced age and his multiple myeloma, a type of blood cancer that inhibits the body’s ability to fight infection. The Centers for Disease Control has noted that immunocompromised adults “may not always build adequate levels of protection” after receiving two vaccine doses.
