NEW YORK - Peter Jennings, the chief ABC News anchorman for more than 20 years, has been diagnosed with lung cancer and will begin outpatient treatment next week, the network said Tuesday.
Jennings, 66, has been feeling ill for the past several months and was replaced Saturday on coverage of the pope's death by anchor Charles Woodruff. He last anchored "World News Tonight" on Friday.
Jennings informed ABC News staff of the diagnosis Tuesday morning and said he will anchor the broadcast when he feels up to it over the next few months as he begins chemotherapy.
"There will be good days and bad, which means some days I may be cranky and some days really cranky," he told ABC News employees in an e-mail.
Charles Gibson, who's in Rome for the pope's funeral, and Elizabeth Vargas will be Jennings' primary substitutes on the evening news.
Jennings first anchored ABC's evening newscast for two years in the 1960s, and was a Europe-based correspondent for the network after that. He started again as an anchor as ABC tried a multi-anchor format starting in 1978, then took over the broadcast himself in 1983.
