Greenie 

Obama analogized to KRS-ONE is perfect/ unless you're also disputing that KRS-ONE is an authority on KRS-ONE and a central figure in rap or that if KRS-ONE says someone is down with him, KRS-ONE is lying?!!?  
That aside, there is no "white house" website example for KRS-ONE...the closest thing is the ever-under-construction Temple of Hip-Hop site which Kris does not own... nor does he own any of the other fan sites out there.
Unless you're theorizing that Greenie has used zillions of dollars in advanced technology just for the sake of manipulating extensive digital and audio of KRS-ONE just to create a camcorder-level video of an endorsement to sell somethingthat he then wouldn't be able to sell anyway without major lawsuits there is no logic 
Is there actually some trend on Wikipedia of artists creating fradulent audio and video of celebrities creating songs with them?
Careful editing is one thing; but let's be realistic here.
