In September 2014, "The New York Times" asserted, "Questions persist after the release of a newly declassified version of a legal memo approving the National Security Agency's Stellarwind program, a set of warrantless surveillance and data collection activities secretly authorized after the terrorist attacks of Sept. 11, 2001." as an introductory headline summary with a link. The accompanying article addressed the release of a newly declassified version of the May 2004 memo. Note was made that the bulk of the program—the telephone, Internet, and e-mail surveillance of American citizens—remained secret until the revelations by Edward Snowden, that to date, significant portions of the memo remain redacted in the newly released version, and that doubts and questions about its legality persist.
