A classified 2010 legal certification and other documents indicate the NSA has been given a far more elastic authority than previously known, one that allows it to intercept through U.S. companies not just the communications of its overseas targets but any communications about its targets as well. The certification - approved by the Foreign Intelligence Surveillance Court and included among a set of documents leaked by former NSA contractor Edward Snowden - lists 193 countries that would be of valid interest for U.S. intelligence. The certification also permitted the agency to gather intelligence about entities including the World Bank, the International Monetary Fund, the European Union and the International Atomic Energy Agency. The documents underscore the remarkable breadth of potential foreign intelligence" collection. An affidavit in support of the 2010 foreign-government certification said the NSA believes that foreigners who will be targeted for collection "possess, are expected to receive and/or are likely to communicate foreign intelligence information concerning these foreign powers." That language could allow for surveillance of academics, journalists and human rights researchers. A Swiss academic who has information on the German government's position in the run-up to an international trade negotiation, for instance, could be targeted if the government has determined there is a foreign-intelligence need for that information. If a U.S. college professor e-mails the Swiss professor's e-mail address or phone number to a colleague, the American's e-mail could be collected as well, under the program's court-approved rules.
