Dan Rather (search) wants to reopen the investigation into President Bush and the National Guard story that resulted in the Memogate (search) scandal.

But his bosses at CBS have forbidden him to go back at it, he said.

"CBS News (search) doesn't want me to do that story," Rather said during an interview that aired on C-SPAN (search) Monday night.

"They wouldn't let me do that story," he said during the shockingly frank interview with former NBC newsman Marvin Kalb.

Rather continues to insist that the story was correct and suggested in the interview that he and the network may have been set up by some outsider.

"There are some strange, and to me, still mysterious things," he said. "Certainly unexplained things that happened about how it got attacked and why, even before the program was over," Rather said.

The report, delivered by Rather last September, was discredited two weeks later after drawing fire, first from politically conservative Web logs and later from mainstream media who reported that the "60 Minutes 2" story was based on forged documents.

Rather retired from the "CBS Evening News" last spring. Some, including CBS chief Les Moonves, have suggested that Rather might have stayed on for at least another year had he not been embroiled in the scandal.

"I believed in the story," Rather said. "The facts of the story were correct.

"One supporting pillar of the story, albeit an important one, one supporting pillar was brought into question," he said. "To this day, no one has proven whether it was what it purported to be or not."
