A Fox News host backtracked on Monday after he said that the death of former Secretary of State Colin Powell raised "new concerns" about vaccines.

"The fact that Colin Powell died from a breakthrough COVID infection raises new concerns about how effective vaccines are long-term," Roberts wrote about an hour after Powell's family announced the death.

Roberts failed to mention that Powell had a compromised immune system due to his treatment for multiple myeloma.

After two hours of criticism on Twitter, Roberts deleted his initial tweet.

"I deleted my tweet about the tragic death of Colin Powell because many people interpreted it as anti-vax. It was not," he wrote. "Yes, Powell had myeloma, but I was still stunned to hear of his passing from COVID."

"His death is a loss for our community and our country. I plan to get a booster as soon as possible," he added.
