1) Anyone can post anything on Wikipedia. Greg could've just joined, went on there, and changed it so he'd be right! (I know he wouldn't do that, no offense intended)
Well, I wouldn't be so sure about that.
2) According to the Episode III Visual Dictionary, a guide to everything, written in affiliation with Lucasfilm, Sweitt Concorkill is an Ongree senator.
Sweitt Concorkill was pictured as an Ongree in the first edition of the Visual Dictionary, and this was later changed by Lucasfilm. If you look in the Complete Visual Dictionary (VD's for all six movies combined into one; published in 2006) I believe that the picture for Sweitt Conkorkill is now that same Vurk as you pointed out to be Flac Gise. The Ongree dude is now said to be named Coleman Kcaj.
NEW QUESTION: What are the names of the two Jedi Padawans being trained by Cin Drallig at the time of Anakin's Jedi Temple assault?
Whie Malreaux and Bene.
