Another big National Security Agency scoop is coming soon, Glenn Greenwald said on Tuesday.
"Just wait a little bit, you'll have it," The Guardian journalist who broke the NSA surveillance story said on "Fox & Friends."
Although Greenwald wouldn't reveal exactly what the new revelations are, he said the world "will be shocked."
"I will say that there are vast programs, both domestic and international spying, that the world will be shocked to learn about, that the NSA is engaged in with no democratic accountability and that's what driving our reporting," Greenwald said.
Greenwald also said President Barack Obama's administration is using leaker Edward Snowden as an example to prevent future whistleblowers from coming forward.
