The former US Vice Presidential candidate has lashed out at the British comedian for "heavily" disguising himself as a "disabled US Veteran, fake wheelchair and all" for his new TV show.
In a lengthy Facebook rant, the former governor of Alaska says she was led to believe she was being offered a "genuine opportunity" to honour American veterans on a "legit Showtime historical documentary".
But she was instead "duped" by Sacha Baron Cohen in a "fake wheelchair". It's understood that he also interviewed Dick Cheney for this new show.
Sarah Palin said: "Yup -- we were duped. Ya’ got me, Sacha. Feel better now? I join a long list of American public personalities who have fallen victim to the evil, exploit(at)ive, sick 'humor' of the British 'comedian' Sacha Baron Cohen, enabled and sponsored by CBS/Showtime."
She added: For my interview, my daughter and I were asked to travel across the country where Cohen (I presume) had heavily disguised himself as a disabled US Veteran, fake wheelchair and all," she wrote. "Out of respect for what I was led to believe would be a thoughtful discussion with someone who had served in uniform, I sat through a long 'interview' full of Hollywoodism’s disrespect and sarcasm -- but finally had enough and literally, physically removed my mic and walked out, much to Cohen’s chagrin.
"The disrespect of our US military and middle-class Americans via Cohen’s foreign commentaries under the guise of interview questions was perverse," she continued, and then issued Cohen, Showtime and CBS a challenge.
"Donate all proceeds to a charitable group that actually respects and supports American Vets," she wrote. "Mock politicians and innocent public personalities all you want, if that lets you sleep at night, but HOW DARE YOU mock those who have fought and served our country. Truly sick."
ShowTime has refused so far to comment.
