Unless the case reaches trial or GZ accepts a plea deal, Crump doesn’t get his cut of whatever TM’s parents win in a civil trial/s. If GZ wins his immunity hearing or the judge grants the motion to dismiss, Crump gets zip.
Maybe Crump can make some money writing a book about the case. Of course he doesn’t have to do the actual writing—Obama’s ghostwriter will probably be happy to help out.
Now I see.... Crump is there for the civil prosecution.
