Isham is CBS News' new D.C. chief


NEW YORK -- CBS News said Thursday that it has hired ABC News investigative chief Christopher Isham as its bureau chief in Washington.

Isham will replace longtime CBS News D.C. bureau chief Janet Leissner, who will retire after a career that included nine years in that post. Isham will take over the D.C. bureau Sept. 4.

Isham is chief of investigative projects at ABC News, with production credits for "World News," "Nightline," "20/20" and "Good Morning America" as well as other platforms. His unit has created the investigative Web site the Blotter, which has broken a number of stories online. He joined ABC News as an associate producer in 1987 and also worked in the documentary unit at NBC News.

Leissner was a senior producer for "CBS Evening News With Dan Rather" from 1992-98 as well as senior producer for the late-night program "America Tonight" and a Washington-based producer for the "CBS Evening News" from 1984-90. She began her career as an associate producer at the Canadian Broadcasting Corp. in Washington.
