Two secret U.S. programs used to track telephone calls and monitor Internet use, which were exposed by Edward Snowden, helped stop terror plots around the world, the head of the National Security Agency said.
The agency provided Congress with “54 cases in which these programs helped disrupt terror plots in the U.S. and throughout the world,” Army General Keith Alexander said today at a conference in Baltimore. Action to stop potential attacks involved other U.S. agencies, such as the Central Intelligence Agency, the Federal Bureau of Investigation, the Pentagon and the Department of Homeland Security, he said.
