Franklin Graham, "Giving Islam a Pass"

I read an article (Newsmax - Franklin Graham) today with a statement from Evangelical leader Rev. Franklin Graham regarding the Obama's administration's role in revoking his invitation to speak at the Pentagon's National Day of Prayer event.  "(President Obama is) giving Islam a pass", was the quote from Graham.  The comment that Graham made to disqualify him from speaking at the Prayer Event was made shortly after 9-11 when Graham said about the Islamic teaching that it is "a very evil and wicked religion".  Everyone was speaking against these terrorists (after 9-11) and now Graham is being singled out as a person who is controversial.
