Colin Powell, the first Black U.S. Secretary of State and Chairman of the Joint Chiefs of Staff, died Monday at the age of 84 from complications of COVID-19, according to a post from his official Facebook page.

Powell was fully vaccinated.

“We want to thank the medical staff at Walter Reed National Medical Center for their caring treatment,” Powell’s family wrote in a statement on Facebook. “We have lost a remarkable and loving husband, father, grandfather and a great American.”
