CNN: No Talk Radio Hosts Allowed

TVNewser reported earlier this morning:

TVNewser has learned, and a CNN spokesperson confirms, that in his morning editorial meeting today, CNN/U.S. president Jon Klein asked his show producers to avoid booking talk radio hosts. "Complex issues require world class reporting," Klein is quoted as saying, adding that talk radio hosts too often add to the noise, and that what they say is "all too predictable."

According to Newser, folks like Lou Dobbs and Bill Bennett are exempt.

I'll be keeping a close eye on this story as it develops.  What's the reason for this decision?
