After the Vanessa Williams incident embarassed everyone involved in pageants, all participants are now required to attest that no potentially embarassing tapes, photos etc. exist that might embarass the entities that put on the pageants. She obviously lied if she attested that no such materials existed.
Pageants are profit seeking enterprises. She lied to be a part of the enterprise in search of her own fame and fortune. She is a sham.
If the truth were known, this is probably why Trump kicked her out after first standing beside her.
