In response to a Freedom of Information Act lawsuit by The New York Times, the government has declassified additional portions of a 2009 report by five agencies’ inspectors general about the Stellarwind program, the group of N.S.A. warrantless wiretapping and bulk phone and e-mail records collection activities initiated by President George W. Bush after the terrorist attacks of Sept. 11, 2001. In 2009, the government released a 43-page unclassified version which omitted discussion of many key facts that then remained secret. In April, the government released an earlier version of this full report. The newly declassified portions largely consist of references to and descriptions of the text of Mr. Bush’s periodic authorizations to the N.S.A, which evolved over time — especially after a March 2004 confrontation with the Justice Department.
