White House press secretary Sarah Sanders issued a searing indictment on Wednesday of former campaign aides and West Wing staffers who spoke ill of the president in a new book by veteran journalist Mike Wolff.

"This book is filled with false and misleading accounts from individuals who have no access or influence with the White House," Sanders said in a statement shared with reporters.

She continued, "Participating in a book that can only be described as trashy tabloid fiction exposes their sad desperate attempts at relevancy."

The book, "Fire and Fury: Inside the Trump White House" by Michael Wolff, sparked a series of news stories on Wednesday after excerpts were released containing critical comments by former White House chief strategist Steve Bannon and other anonymous Trump allies.

Bannon told Wolff he considered the infamous Trump Tower meeting between Donald Trump Jr., Jared Kushner, Paul Manafort, and a Russian lawyer – a focal point of the Russia investigation – as "treasonous." The Breitbart chairman, who left the White House last August, also said there was a "zero" percent chance the president himself wasn't aware of the meeting at the time.

Furious over Bannon's comments, President Trump issued a statement late Wednesday afternoon claiming his former aide "lost his mind" when he left the West Wing.

"Steve Bannon has nothing to do with me or my Presidency," Trump says.
