SENATE RESOLUTION 597--URGING THE RELEASE OF INFORMATION REGARDING THE

SEPTEMBER 11, 2001, TERRORIST ATTACKS UPON THE UNITED STATES

Mr. BLUMENTHAL (for himself, Mr. Schumer, Mrs. Gillibrand, Mr. Murphy, and Mr. Menendez) submitted the following resolution; which was referred to the Committee on Homeland Security and Governmental Affairs:

S. Res. 597

  Whereas tens of thousands of pages of documents relating to 
 the September 11, 2001,

[Page S5458]

terrorist attacks upon the United States remain classified by 
 the Federal Government;

  Whereas the contents of these documents are necessary for a 
 full public understanding of the events and circumstances 
 surrounding the September 11, 2001, terrorist attacks;

  Whereas the decision to maintain the classified status of 
 many of these documents prevents the people of the United 
 States from having access to information about the September 
 11, 2001, terrorist attacks, including the involvement of 
 certain foreign governments in the attacks; and

  Whereas the people of the United States and the families of 
 the victims of the September 11, 2001, terrorist attacks 
 deserve full and public disclosure of the events surrounding 
 the attacks: Now, therefore, be it

  Resolved, That it is the sense of the Senate that--

  (1) documents related to the events of September 11, 2001, 
 should be declassified to the greatest extent possible; and

  (2) the survivors, the families of the victims, and the 
 people of the United States deserve answers about the events 
 and circumstances surrounding the September 11, 2001, 
 terrorist attacks upon the United States.
