Donald Trump is not happy about the allegations that Miss USA 2012 has been rigged by former Miss Pennsylvania Sheena Monnin, who resigned from her post after Sunday night's pageant. Trump, who owns and heads the Miss Universe organization has reportedly launched an investigation into allegations that the pageant was rigged, reports TMZ. The billionaire is even planning to SUE Monnin.

Former Miss Pennsylvania 2012 Sheena Monnin sensationally resigned from her post, accusing the pageant organizers of rigging the top five contestants. She claimed that a fellow contestant saw the list with the top five names even before the pageant kicked off on Sunday evening in Las Vegas.

Trump told "Today" that Monnin's accusations are ridiculous and that his organization now plans to sue for her accusations. "What we've authorized today is we're going to bring a lawsuit . She said some really strong things. When she's using the word 'fraud,' that's pretty strong, so we're going to be suing her on that basis." 

Miss Pennsylvania Sheena Monnin posted a statement on her Facebook page:  "I have decided to resign my position as Miss Pennsylvania USA 2012. Effective immediately I have voluntarily, completely, and utterly removed myself from the Miss Universe Organization. In good conscience I can no longer be affiliated in any way with an organization I consider to be fraudulent, lacking in morals, inconsistent, and in many ways trashy. I do not support this system in any way. In my heart I believe in honesty, fair play, a fair opportunity, and high moralgrity, none of which in my opinion are part of this pageant system any longer. Thank you all for your support and understanding as I walk a road I never dreamed I'd need to walk, as I take a stand I never dreamed I'd need to take. After 10 years of competing in a pageant system I once believed in, I now completely and irrevocably separate myself in every way and on every level from the Miss Universe Organization. I remove my support completely and have turned in the title of Miss Pennsylvania USA 2012."

Monnin claims that her fellow contestants had even seen a list of the top five girls that were chosen - even before the show aired on Sunday evening. "I witnessed another contestant who said she saw the list of the Top 5 BEFORE THE SHOW EVER STARTED proceed to call out in order who the Top 5 were before they were announced on stage," she said. She said when the top five contestants were indeed the top five which she saw on the list, that is when she knew that it was rigged. "I decided to distance myself from an organization who did not allow fair play and whose morals did not match my own," she added.
