JUNEAU, Alaska (AP) — A publisher is standing behind a book about Sarah Palin, a day after Palin's attorney threatened to sue over it.Crown Publishers spokesman Stuart Applebaum says the company is confident the reporting in Joe McGinniss' book is "solid, reliable, and well-substantiated." Applebaum says Crown stands behind McGinniss and the book, "The Rogue: Searching for the Real Sarah Palin."Palin attorney John Tiemessen, in a letter to Crown Publishing Group Monday, claims the book defames the Palins and contains "lies and rumors."Tiemessen cited an email McGinniss reportedly sent a blogger in January seeking substantiation for several rumors that have surrounded Palin's family. Andrew Breitbart posted that email online last week.Tiemessen says McGinniss' book contains "most of" the stories that "amounted to the wishful fantasies of disturbed individuals."
