Fox News host Tucker Carlson joined the calls from at least two Republican lawmakers for a full investigation into the National Security Agency (NSA) allegedly spying on his texts and emails, after the agency rebuffed claims that he is the "target" of a surveillance investigation. Carlson reiterated Wednesday on "Tucker Carlson Tonight" that he does not make the claim lightly, and that the NSA's statement on Tuesday does not directly deny any spying has or is taking place; only that he is not the "target." Investigative journalist Glenn Greenwald concurred, insofar as the NSA has a multitude of other ways to capture American citizens' data without them being the formal "target" of an investigation.
