Herman Cain, the former Republican presidential candidate and co-chair of Black Voices for Trump, has died at the age of 74 after a month-long battle with COVID-19. Cain’s last public appearance came on June 20, when he tweeted a photo of himself at a Trump rally in Tulsa, Oklahoma. Cain wore no mask at the event, which featured thousands of people packed tightly together. He tested positive for the coronavirus 11 days after Trump’s rally, where campaign officials discouraged mask use and were filmed removing social distancing stickers inside the arena.

Cain was the former CEO of Godfather’s Pizza and a cancer survivor. In 2012, he was briefly the front-runner for the Republican presidential nomination, but later withdrew from that year’s race after three women accused him of sexual harassment.
