Fox News has been one of the biggest supporters of James O'Keefe, who is infamous for dressing up as a pimp and videotaping ACORN staffers offering to help the supposed pimp and his prostitutes secure funding for a brothel. The network constantly replayed coverage from his operation. In September, Fox News Sunday host Chris Wallace named O'Keefe his "Power Player of the Week," calling him an "undercover reporter" and a "fascinating character."

Yesterday, the FBI arrested O'Keefe and three others - "charged with entering federal property under false pretenses with the intent of committing a felony" - saying that they were plotting to wiretap Sen. Mary Landrieu's office (D-LA). One of the other men, Robert Flanagan, is the son of William Flanagan, the acting U.S. Attorney for the Western District of Louisiana. Two of the men "dressed as telephone company employees" and showed up to Landrieu's New Orleans office, saying they had to "fix phone problems." O'Keefe was already there and was "positioning his cell phone in his hand to videotape the operation".
