The cover-up in Washington of possible Saudi ties to Al Qaeda and 9/11 continues.

The Treasury Department is now refusing to release the names of Saudi individuals and organizations that the U.S. has investigated for possible links to Al Qaeda and other similar groups.

Just a week ago the Treasury Department promised to give Senators the information, but yesterday the Department reversed itself and announced the data had become classified.

Yesterday Pennsylvania Sen. Arlen Specter, a Republican, threatened to subpoena the Treasury Department for the information.

The White House recently classified a 28-page section of the Congressional 9/11 report that dealt with Saudi ties to the Sept. 11 attacks.

It has also been revealed that a top Treasury official last week told Senate staff members that the State Department had intervened on a number of occasions to keep the Treasury Department from adding certain Saudi entities to its watchlist of terror suspects.
