Katie Couric isn't going anywhere, former CBS News President Andrew Heyward said at a media conference in Manhattan on Wednesday, the Los Angeles Times reports.

"Despite what some critics have suggested, Heyward said it was far too early for CBS to abandon the effort."

Here is Heyward's theory about the shifting evening news ratings: "People who liked Bob Schieffer said, 'She's not like Bob Schieffer. Who's more like Bob Schieffer? Charlie Gibson is.' So they switched."
