"Going Rogue" has gone platinum.

HarperCollins spokeswoman Tina Andreadis said Tuesday that just two weeks after publication, Sarah Palin's memoir has sold 1 million copies. The print run for "Going Rogue" has been increased again, to 2.8 million copies. The original printing was 1.5 million, then moved up to 2.5 million.

"Going Rogue" joins a select club of million-selling political memoirs that includes Barack Obama's "The Audacity of Hope," Hillary Rodham Clinton's "Living History" and Bill Clinton's "My Life."
