“Our author knows that the President is determined to unmask whistleblowers who may be in his midst. That’s one of the reasons A WARNING was written,” the literacy agency Javelin said in a statement. “But we support the publisher in its resolve that the administration’s effort to intimidate and expose the senior official who has seen misconduct at the highest levels will not prevent this book from moving forward.”
