From the AP story on Yahoo! News:

Fox News Channel apologized on-air Tuesday for running tape of a different congressman while reporting Monday on the indictment of Rep. William J. Jefferson on bribery charges.

The network ran footage of House Judiciary Committee Chairman John Conyers of Michigan instead of Jefferson. Both congressmen are black.

Fox blamed the mistake on a 22-year-old production assistant hurriedly grabbing a wrong videotape. Fox's Washington bureau chief, Brian Wilson, said he was mortified by the error.

On Tuesday, Fox News anchor Martha MacCallum said about the Jefferson story: "We mistakenly ran the wrong videotape accompanying that story and we apologize for that error."

The apology apparently wasn't accepted by Conyers.

"Fox News has a history of inappropriate on-air mistakes that are neither fair, nor balanced," he said Tuesday. "This type of disrespect for people of color should no longer be tolerated. I am personally offended by the network's complete disregard for accuracy in reporting and lackluster on-air apology."
