Saudi Coverup

The 9/11 deaths were a tragedy.  Other tragedies were the resulting wars in Iraq and Afghanistan, the destruction of American civil liberties, and the cover-up of Saudi national's overwhelming involvement in the 9/11 plots.

Why does Obama continue to allow Saudi involvement in 9/11 to be covered up?

After the 9/11 attacks, the public was told al Qaeda acted alone, with no state sponsors.
But the White House never let it see an entire section of Congress’ investigative report on 9/11 dealing with “specific sources of foreign support” for the 19 hijackers, 15 of whom were Saudi nationals.  It was kept secret and remains so today.
