When Erica Hill left "Anderson Cooper 360" for CBS News last year, former CNN honcho Jon Klein sneered at the sassy sidekick that she was going nowhere fast. An insider says Klein told her, "Why are you going there? It's not like you're anchoring the 'Evening News.' " Photogenic Hill started as a newsreader for "The Early Show" and anchored the Saturday edition. Now, she's having the last laugh. CBS News announced yesterday that Hill and Chris Wragge will take over as the new morning anchor team, succeeding Harry Smith and Maggie Rodriguez. A source close to Hill quoted her as saying "Jon Klein is a very dear friend and he has never been anything but fully supportive of my career." An industry insider buzzed that the morning show shakeup happened partly because "CBS has no money to spend. Harry Smith was more expensive than they can afford." But a CBS News source said, "Bringing in this new team is a decision focused on improving the show. Payroll and cost were not the basis for the decision."
