Michelle Obama at odds with White House brass?

Washington is buzzing Monday morning over a new book about the First Family, which paints first lady Michelle Obama as a powerful behind-the-scenes player in her husband's White House.

New York Times reporter Jodi Kantor, in a book to be published Tuesday, portrays a White House where tensions developed between Mrs. Obama and former White House Chief of Staff Rahm Emanuel and former press secretary and presidential adviser Robert Gibbs.

CBS News obtained a copy of the book, and Chief White House correspondent Norah O'Donnell says there was a lot of disagreement in the White House about whether they should cooperate with the author. While some advisers did speak to Kantor, the Obamas themselves did not grant any interviews, fearing it would only result in gossipy, salacious details that would not help their image.

O'Donnell says the pressure of White House life was certainly being felt by the first lady, and there were the unique pressures of being the nation's first black first lady.
