A new book by former CBS reporter Sharyl Attkisson charges that the network banned her from going on Laura Ingraham’s radio show.

“Stonewalled” alleges that CBS News told Attkisson not to appear on Ingraham’s show anymore following an appearance on the show to discuss the botched “Fast and Furious” operation.

Ingraham was on “The Factor” to discuss, telling Bill O’Reilly that she had spoken to Attkisson on many other stories, and there was never a problem.

“She should have gotten a promotion at CBS, not being told you can’t go on various shows,” Ingraham said, noting that this was a big story that Attkisson blew wide open.
