In a note on her Facebook page, she says that she believes Sunday's Miss USA competition was fixed. She said she saw evidence that the top five contestants were selected before they were announced on Sunday's show.
"I will relay to you the reasoning behind my resignation. 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 writes in a Facebook page note. "Apparently the morning of June 3rd she saw a folder lying open to a page that said 'FINAL SHOW Telecast, June 3, 2012' and she saw the places for Top 5 already filled in."
Monnin, who has a master's degree in psychology, adds in a separate Facebook post:
"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 moral integrity, none of which in my opinion are part of this pageant system any longer."
But there seems to be some question about exactly why she is resigning.
In a statement, the Miss Universe Organization dismissed Monnin's allegations as "false" and said Monnin told pageant officials she was resigning because she did not agree with the organization's recent decision to admit transgender contestants.
Pageant officialsreleased an e-mail message they said they received from Monnin on Monday that read, "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. This goes against ever (sic) moral fiber of my being."
Miss USA winner Olivia Culpo answered a question on Sunday's show saying that transgender contestants should definitely be able to participate in the pageant.
Donald Trump is firing back at Monnin. On Good Morning America today he said he's "going to be suing her," for her "very false charge." He called the whole thing "totally ridiculous," adding. "Nobody knows anything. Ernst & Young (accounting firm) doesn't even know until they tabulate."
He got harsh with Monnin, adding, "It's loser's remorse. If you look at her... you understand why she's not in the Top 15."
He said his "people" have already interviewed the person whom Monnin claims saw the Top 5 written in advance and "that person said it's not true."
Trump went on to say there's no motivation for fixing the contest. "It's not like we care who the final contestants are. What it is it is."
As for whether it might really be the transgender decision that Monnin objects to, Trump said, "I don't think she had an issue with that. I think her primary issue is she lost and she's angry about losing. In my opinion, I saw her for barely a second she didn't deserve to be in the top 15." Ouch!
