(ETA: As I think Ksig and Mystic said earlier) All of this talk about the revised speech is in reference to the revised lesson plans from the Dept. of Ed. The lesson plans were revised due to some criticized content (in light of Obama's speech).
I don't doubt that the actual speech may have been edited--as speeches are--but we may never know either way.
Either way, these faux-controversies are all a hobglob distractions from core issues.
