Obama doesn't want 9/11 sources revealed

See this story. There's 28 pages of the 9/11 report being withheld for 'security' reasons. Some speculate that it reveals Saudi Arabia's (SA) direct support in the 9/11 attacks. And now there's a Bill to open up that investigation and allow victims to sue SA. The White House released a response basically saying no, can't happen and let's not look into it ever again. By the way, Sanders wants those 28 pages released to the public.
