"The performance of the United States Government in the years leading up to the terrorist attacks on September 11, 2001 was hindered by inadequate information sharing between key agencies of the Federal government. The Intelligence Reform and Terrorism Prevention Act (IRTPA) of 2004 assigned to the National Counterterrorism Center (NCTC) the responsibility 'to ensure the agencies, as appropriate, have access to and receive all-source intelligence products needed to execute their counterterrorism plans or perform independent, alternative analysis,' and 'to ensure that such agencies have access to and receive intelligence needed to accomplish their assigned activities.' NCTC statutory authorities are limited to sharing with Federal organizations. This report focuses on the progress that NCTC, working with its Federal partners, has made in the years since 9/11. It does not address the many efforts by other departments and agencies to improve information sharing at the Federal level and with non-Federal partners."
