House Intelligence Committee chairman Mike Rogers said Sunday that Glenn Greenwald, the Guardian reporter and columnist who broke the story of the National Security Agency’s broad surveillance of the Internet and phone activity of American citizens, “doesn’t have a clue” about the nature of the program.

Rogers argued that Greenwald’s disclosures pose security risks to the nation, and both Rogers and Senate Intelligence Committee chairwoman Dianne Feinstein said that Greenwald’s source should be prosecuted.

“He doesn’t have a clue how this thing works,” Rogers told George Stephanopoulos. “Neither did the person who released just enough information to literally be dangerous.”

Neither Greenwald’s source nor Greenwald himself, Rogers argued, accurately portrayed the NSA’s data-mining program, which in reality accesses the information of foreign nationals on a limited basis and only with the permission of American courts.

“Putting just enough [information] out there to be dangerous, is dangerous to us,” Rogers said. “It’s dangerous to our national security and it violates the oath of which [the leaker] took.”
