Trying to discredit FR.
The question is why is he?
He's trying to elevate Bill O'Reilly. He doesn't care who he discredits in the process.
He needs to keep his "Fair & Balanced" credentials current. This is one of the ways he does it. His incoherent environmental views and his opposition to taking out Saddam are others. It's all contrived. He's not a real person, he's a packaged television personality.
