The top Trump adviser who chose not to write a tell-all book

Peter Bergen wrote an article in CNN discussing Battlegrounds, the book recently published by Retired Lt. Gen. H.R. McMaster.

In the preface to "Battlegrounds," McMaster acknowledges that despite the advice of friends, editors, agents and even family members, he chose not to write a paean to Trump "as an unconventional leader who ... advanced American interests," nor did he write a takedown depicting the President as "a bigoted narcissist unfit for office," despite the fact that writing either of these types of books "might be lucrative."
