SIGINT
"In an official statement from July 30, 2013, the NSA said "XKeyscore is used as a part of NSA's lawful foreign signals intelligence collection system. ..." to legally obtain information about "legitimate foreign intelligence targets in response to requirements that our leaders need for information necessary to protect our nation and its interests. ... to collect the information, that enables us to perform our missions successfully – to defend the nation and to protect U.S. and allied troops abroad"
That includes our elections process.
And the election process was recently included in the list of DHS tasks/protection, right?
