Why did President Bush clify 28 pages of the 9/11 Commission Report that described Saudi ties to 9/11?

Yes i heard about the Saudi ties to 9/11 also. I heard that in Saudi Arabia they were questioning a supposed suspect and they had CIA agents dressed as saudi authorities. The suspect immediately started asking them to call the saudi prince, saying that he would know what to do. We could try to bring in the saudi princes he was asking for. Only they're all dead now. How convenient.
