Charles Gibson will step down as anchor of ABC's World Newsin January and be replaced by his onetime Good Morning Americaand Primetimeco-host Diane Sawyer, ABC News President David Westin announced today (Wednesday). In a message to colleagues, Gibson said that he had planned to step down in 2007. "But with Peter [Jennings's] illness, Bob [Woodruff's] injuries, and Elizabeth [Vargas's] pregnancy, the job at World Newscame open in May of 2006, and David asked me to step in as anchor. It was an honor to do so." Gibson said that he hoped to be able to contribute "occasionally" to ABC News in the future, "and we will be discussing what that role might be." In a separate statement, Westin said, "Diane Sawyer is the right person to succeed Charlie and build on what he has accomplished." Westin did not indicate who will replace her on Good Morning America or even whether she will be leaving GMA at the same time she takes over the evening newscast. (For a time following Jennings's death she and Gibson alternated as news anchors.) Sawyer did not immediately issue a statement. She has repeatedly denied reports that she lobbied for the anchor post following Jennings's death and was infuriated when she was passed over.

One of three men detained by the U.S. military in connection with the roadside bombing in Kabul in which CBS News correspondent Cami McCormick was seriously injured had a telephone number for an office in the Afghan Defense Ministry, CBS correspondent David Martin reported Tuesday. He noted that shortly after the three suspects were taken into custody an Afghan official intervened on their behalf, claiming that they were not involved. However, Martin said, investigators had already gathered substantial evidence against the men, including fingerprints and residue from the explosion on at least one of them. One soldier was killed in the bombing; McCormick suffered broken arms, legs and other injuries, and two other troops received minor wounds.

But it was all CBS after that among the top ten as the network remained the most-watched network for the 12th time in the 14 weeks of the summer season.
