“ABC World News” anchor Diane Sawyer has the first television interview with author and journalist Bob Woodward, who is promoting his upcoming book Obama’s Wars.

The book is due to be released September 27, and Sawyer’s interview will air that day. Excerpts will also run on “Good Morning America” and “Nightline.”

Woodward, of course, is one-half of the team that brought down President Richard Nixon during Watergate. His previous book, The War Within, focused on the Bush Administration’s internal dialogue and debate about the Iraq war.

Update: Woodward will also appear live on “GMA” Sept. 28 to discuss the book.

The new book will give “an insider’s account of President Obama at work with his team,” according to an official description. “Drawing on internal memos, classified documents, meeting notes and hundreds of hours of interviews, Woodward focuses on Obama’s critical decisions about the wars abroad and the worldwide fight against terrorism.
