Monica Lewinsky is one of the producers of the upcoming series “Impeachment: American Crime Story”.  But that doesn’t mean she sugarcoated the way she was portrayed.   Originally, the writer left out a scene where Monica flashed her thong to BILL CLINTON, because she didn’t want to “re-traumatize” Monica.  But Monica made her put it back in.   She says, quote, “I’m incredibly experienced in understanding how people see this story.  So, ultimately, I felt two things:   “One was that I shouldn’t get a pass because I’m a producer;  and two, that it was unfair to the team and to the project because it would leave everybody vulnerable.”   “Impeachment” debuts on September 7th on FX . . . starring Beanie Feldstein as Monica, Clive Owen as Bill, Edie Falco as Hillary Clinton, and Sarah Paulson as Linda Tripp.
