Speculation seems to be that Novak sang, and that someone in the administration may be facing a perjury charge.
Probe Into Leak of CIA Agent's Identity May Be Nearly Complete// (Washn)

WASHINGTON--The special prosecutor investigating whether Bush administration officials illegally revealed the identity of a covert CIA operative says he finished his investigation months ago, except for questioning two reporters who have refused to testify.
The information in a March 22 court filing by special counsel Patrick Fitzgerald suggests that syndicated columnist Robert Novak, who first published the name of undercover CIA officer Valerie Plame, has already spoken to investigators about his sources for that report, according to legal experts. Novak, whose July 2003 column sparked the investigation, and his attorney have refused to comment on whether he was questioned by prosecutors.
Legal experts and sources close to the case also speculated Wednesday that Fitzgerald is not likely to seek an indictment for the crime he originally set out to investigate--whether a government official knowingly exposed a covert agent. The sources, who asked not to be named because the matter is the subject of a grand jury investigation, said Fitzgerald may instead seek to charge a government official with committing perjury by giving conflicting information to prosecutors.
Fitzgerald's court filing was part of his effort to persuade the U.S. Court of Appeals in the District of Columbia that he needs the testimony of New York Times reporter Judith Miller and Time magazine reporter Matt Cooper to wrap up his two-year investigation.
The two reporters and their news organizations have refused to discuss their confidential sources with prosecutors. They appealed the dispute to the full court after a three-judge panel ruled last month that Miller and Cooper should be held in contempt and face possible jail time unless they agree to be questioned before a grand jury.
In the court documents, Fitzgerald said that by October 2004, ``the factual investigation--other than the testimony of Miller and Cooper ... was for all practical purposes complete.''
``The investigation has since been stalled by (the reporters') refusal to comply with an order to testify,'' he and deputy special counsel James Fleissner wrote.
That special prosecutor's characterization of his efforts led to indignitzgerald would not interview Novak.
``This would lead me to probably conclude that Mr. Novak testified and did not provide nearly the treasure trove that Fitzgerald expected, '' Dalglish said.
