Former US National Security Adviser John Bolton has signed a $2 million book deal with Simon & Schuster, three publishing officials have told the AP.
However, the sources said that the title of the book and the release date have not been revealed yet.
Bolton is reportedly represented by Javelin literary agency that is also known for representing former FBI chief James Comey and the anonymous White House official whose book titled "A Warning" is set to be released this month.
The reports came less than a week after Bolton's departure from the White House over his disagreements with US President Trump.
Bolton warned then that he would have his say "in due course”.
