White House Speeds Release of Report on Changes to N.S.A. WASHINGTON - The White House said on Wednesday that it would release later in the day a report of a presidential advisory committee that issued more than 40 recommendations about how to alter the National Security Agency's data gathering at home and abroad. The announcement by the White House press secretary, Jay Carney, came just after President Obama met with the five members of his review board in the Situation Room, where they explained a series of recommendations that one official described as "significantly more far-reaching than many expected." According to officials familiar with the report, the advisory group called for continuing the bulk collection of data about telephone calls, but moving it to private hands, a process that officials say could take several years. Some members of the group also favored splitting command of the N.S.A., which conducts surveillance, from the United States Cyber Command, the Pentagon's cyberwarfare unit, to avoid concentrating too much power in the hands of a single individual. But Mr. Obama has rejected that approach. The report is also highly critical of some of the N.S.A. practices that have most angered technology companies, like the agency's effort to make sure that the government can gain access to all encrypted communications, and the purchase by government agencies of information about previously undiscovered flaws in common software, especially Microsoft Windows, that could be exploited by government hackers. These are known as "zero day" flaws because they have never been seen before and thus give the N.S.A. and the Cyber Command a way to launch attacks on foreign computer systems. That was a key technique in the American and Israeli joint attacks on Iran's nuclear enrichment facilities, but it also sews distrust in American products. These recommendations are likely to be opposed by many in the intelligence community, for fear that they will tie the hands of the agencies as they seek to break the encrypted conversations of terrorist groups, rogue states, nuclear proliferators and others. Initially, the White House had intended to release the report in January, simultaneous with Mr. Obama's decisions about how to respond to it, and Mr. Carney had repeated that time frame as recently as Tuesday. But on Wednesday, Mr. Carney said that by making the report public, Americans could judge the contents of the findings themselves. The decision, however, puts more pressure on Mr. Obama after a federal court said this week, for the first time, that bulk collection of data about telephone calls made by Americans was probably unconstitutional. It also comes amid complaints from business executives that N.S.A. surveillance methods revealed by Edward J. Snowden, the former contractor who disclosed many of the agency's programs, were harmful to American businesses trying to sell hardware, cloud services and social networks abroad. Mr. Obama has embraced the bulk collection program, though officials say he may agree to the recommendations that the telephone "metadata" - essentially the same kind of information that is contained in a telephone bill about numbers called and the duration of conversations - be held by private industry. Many telephone companies have been reluctant to retain that data beyond 18 months, because of the cost and the fear that it would be sought in private legal actions, including divorce cases. It is possible that a consortium of private companies may be created to organize the data in one place, but keep it from government hands unless a warrant for the data is issued by the Foreign Intelligence Surveillance Court. Mr. Obama also has decided to retain the system, begun in 2009, in which a military officer oversees both the N.S.A. and its sister agency at the Pentagon, the Cyber Command. The Cyber Command is responsible for defensive and offensive cyberoperations, including electronic attacks on foreign countries or terrorist groups, but it is heavily reliant on the abilities of the N.S.A.
