A posting on Sheena Monnin's Facebook page dated Monday says she's resigned. In another post, Monnin claims another contestant saw the list of top 5 contenders on Sunday morning, hours before the pageant was broadcast.

Trump, whose Miss Universe organization owns the Miss USA pageant, called into NBC's Today show and said they will sue Monnin.

Pageant organizers confirm Monnin has resigned, but not for the reason she claims. A statement from the organization includes text from an email it says Monnin sent citing the decision to allow natural born males into the competition as the reason she's resigning.

Sheena Monnin's Facebook Statement

"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. 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."

After announcing her resignation, Monnin posted another facebook message:

“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. After it was indeed the Top 5 I knew the show must be rigged; I decided at that moment to distance myself from an organization who did not allow fair play and whose morals did not match my own."
