Miss USA Contestant: Pageant is 'Fixed,' 'Lacking in Morals'S

Miss Pennsylvania USA 2012 Sheena Monnin resigned her role in an angry Facebook post that accused the Miss USA pageant officials of fixing the contest and having the finalists all picked out prior to the show's airing.

The 27-year-old claims to have witnessed another contestant calling out the names of the top 5 finalists "before they were announced on stage." The unnamed contestant allegedly obtained the list from a folder she found lying around.

"Thinking she was just seeing a rehearsal fake top 5 from a previous day she walked away," Monnin writes, "then realized that it had without a doubt been labeled as the Final Show Telecast, June 3rd."

But fraud isn't the only reason Monnin has decided to hand in her crown.

She goes on to blast the organization's lack of morals, a claim she elaborates on in an email sent directly to pageant officials.

"I refuse to be part of a pageant system that has so far and so completely removed itself from its foundational principles as to allow and support natural born males to compete in it," Monnin says, referring to Miss Universe Canada's precedent-setting transgender contestant Jenna Talackova.

By stark contrast, Olivia Culpo, winner of the 2012 Miss USA pageant, expressed support for transgender contestants during the Q&A portion of Sunday's show.

Donald Trump, owner of the Miss USA contest, has responded to Monnin's allegations, calling them "absolutely ridiculous" and "loser's remorse." He said he plans to sue Monnin for making false charges.
