“This guy is mentally retarded. He’s this dumb Southerner,” Trump reportedly told Porter while using a Southern accent. “He couldn’t even be a one-person country lawyer down in Alabama.”

Woodward, a veteran journalist known for his reporting on the Nixon-era Watergate scandal as well as a series of tell-all books on past administrations led by presidents of both parties, is releasing his new book on Sept. 11.

“Fear: Trump in the White House” reportedly offers a detailed account of the inner workings of the Trump administration. 

Woodward’s account is based on “hundreds of hours of interviews with firsthand sources, meeting notes, personal diaries, files and documents.”

The book's release date comes less than two months before the midterm elections.
