Oral Argument: New Tell-All Claims Katie Couric Joked Diane Sawyer ‘Blew’ Source For Story

A new tell-all book is looking to blow the lid on long-standing rivals Katie Couric and Diane Sawyer.

Sheila Weller’s book, The News Sorority, sheds light on the backstabbing that allegedly took place as Couric, Sawyer and Christiane Amanpour fought their way to the top.

The news anchors reportedly were bitter rivals while working for the TODAY show and Good Morning America. As their feud worsened, Weller’s book claims that Couric even threw Sawyer some serious shade when she found out that her competition had beaten her to an interview.

Couric allegedly was overheard saying, “I wonder who she blew this time to get it.”

The book, which is slated for a September release, also dives into Couric’s controversial move from TODAY to CBS News, a decision that not only earned her a big pay raise (to the tune of $15 million) but also a firestorm of controversy.

“In private, Katie - who had recently turned 50 - was now beginning to actively and repeatedly compare herself to the embattled but energized Hillary Clinton,” the book claims. “Katie deeply related to Hillary; she felt she was being pummeled as the first female anchor just like Clinton was being pummeled as the first major female presidential candidate.”

While Couric was allegedly feeling alienated, Sawyer was reportedly at war with news icon Barbara Walters. The book quotes an ABC News staffer who claimed “Barbara and Diane were determined to kill each other -- to wipe each other off the face of the earth.”

But according to reports, the new book’s claims are “just too ridiculous to consider.”
