When CBS chief Les Moonves made a surprise visit to a CBS Evening News staff meeting today – with Katie Couric, Sean McManus, and exec producer Rick Kaplan all in attendance – he spent about 10 minutes restating his support for his $15 million gal, while Katie thanked her team for dealing with all the speculation about their leader. We also hear Les, on his way out, told one staffer that today’s Keith Kelly report, about Katie writing a tell-all book, is “all lies.” Which is probably true, but as if Katie would fill him in on it.
