CBS News is on defense after confusing an ailing black congressman with a deceased one.

While airing a story Monday on Georgia Rep. John Lewis undergoing treatment for Stage 4 pancreatic cancer, the news network showed a photo of Maryland Rep. Elijah Cummings, who died earlier this year.

Shortly after the mix-up, the network issued a statement apologizing.

Tonight on the 6:30 p.m. ET broadcast of the CBS Evening News, one photograph was misidentified as Congressman John Lewis,” CBS Evening News wrote.

“We have replaced the photo in all broadcasts and platforms. We deeply regret the error.”
