On Dan Rather's final broadcast, Dan Rather will briefly talk to viewers about the end of his tenure, the AP's David Bauder reports. "It is a particularly trying time for CBS News and the CBS Evening News, " EP Jim Murphy says. "We would just like to do our jobs well and have our work graded on the strength of the newscast. This sideshow that is going on with the media who want to have fun picking on Dan ... It's not good and it's not fun for us."
