Sen. Bernie Sanders (I-VT) had a productive holiday break,
asking the National Security Agency if "the NSA spied, or is the NSA currently spying, on members of Congress or other American elected officials?" The NSA
responded:
“NSA’s authorities to collect signals intelligence data include procedures that protect the privacy of US persons. Such protections are built into and cut across the entire process. Members of Congress have the same privacy protections as all US persons. NSA is fully committed to transparency with Congress. Our interaction with Congress has been extensive both before and since the media disclosures began last June.
“We are reviewing Senator Sanders’s letter now, and we will continue to work to ensure that all members of Congress, including Senator Sanders, have information about NSA’s mission, authorities, and programs to fully inform the discharge of their duties.”
In other words, yes, they are treating members of Congress like every other American, and thus are collecting mass data from them along with everyone else, though apparently they're working on a more complete response. Given that the NSA has
admitted to baldly lying to Congress, further clarification probably won't be too convincing.
