Critics of NSA spying, including Glenn Greenwald, to testify before Congress

Democratic congressman Alan Grayson is leading a bipartisan group of representatives concerned about "constant misleading information" from the intelligence community. They're holding a hearing Wednesday, at which critics of the National Security Agency's spying programs will speak. One of them is Glenn Greenwald, who will participate remotely from Brazil. I'm sure the NSA will want to listen in on that line.
