UPDATE: Just when everyone seemed to have forgotten about -- or at least moved on from -- The Rogue, Sarah Palin's camp has brought the controversial book right back to the forefront by threatening to sue its author and publisher for "knowingly publishing false statements."

In a letter sent to the Crown Publishing Group, which was obtained by ABC News, Palin's family attorney, John Tiemessen, warns the publisher that Palin is weighing a lawsuit and requests that the company does not delete any emails or destroy any records related to the book or its author, Joe McGinniss.
