Fitzgerald says Libby says he heard it from reporters. Big difference.
Indictment: "LIBBY confirmed for Cooper, without qualification, that LIBBY had heard that Wilsons wife worked at the CIA"
What Cooper claims he said and the indictment says that Cooper said are essentially the same.
The whole thing seems like a tempest in a teapot, but apparently this prosecutor is not going to let Libby get away with false statements to the FBI and the grand jury. Either he believes that Libby lied intentionally or he is using the indictment to pressure Libby.
