Just saw on Yahoo News an AP report that CNN is fed up with McCain/Palin. McCain told CNN that they could film Palin meeting with world leaders, but there would be no press conference. In retailiation, CNN is pulling the cameras:
CNN, which was providing the television coverage for news organizations, decided to pull its TV crew, effectively denying Palin the high visibility she had sought.
