Actor Sean Penn’s debut novel’s main character calls for the assassination of the president and dares the commander in chief to ‘Tweet me, b****’, DailyMail.com can reveal.

The two-time Oscar winner’s 176-page fiction, titled Bob Honey Who Just Do Stuff, is about a ‘modern American man, entrepreneur, and part-time assassin’.

The main character, septic tank cleaner Bob Honey, tells tales of working with military contractors in Iraq, being employed by the government to kill the nation’s resource-draining elderly, and meeting an El Chapo-esque drug lord who had just escaped prison.
