"Michelle Obama and the Evolution of a First Lady" [Jodi Kantor, New York Times]
The Obamas [Amazon]
Update #1:
"White House pushes back against Kantor" [Politico]
“This is the author’s take, reflecting her own opinions, on a remarkably strong relationship between the President and First Lady – both of whom share an unwavering commitment to each other, and to improving the lives of Americans,” White House spokesman Eric Schultz said in a statement. “The book, an overdramatization of old news, is about a relationship between two people whom the author has not spoken to in years. The author last interviewed the Obamas in 2009 for a magazine piece, and did not interview them for this book. The emotions, thoughts and private moments described in the book, though often seemingly ascribed to the President and First Lady, reflect little more than the author’s own thoughts. These second-hand accounts are staples of every Administration in modern political history and often exaggerated.”
Update #2: Two reviews of The Obamas worth a read:
"Partners in Love and the Presidency" [New York Times]
