The NSA has released a statement sidestepping questions about whether it spies on members of Congress. On Friday, Senator Bernie Sanders (I-VT) asked NSA head Keith Alexander if the agency was spying, or had ever spied, on American Congress members or other elected officials. Today, the NSA provided an equivocal answer, promising that Congress has the same privacy protections as all US persons. NSAs authorities to collect signals intelligence data include procedures that protect the privacy of US persons, reads the statement, provided to The Guardian. Such protections are built into and cut across the entire process.
