Ex-Ambassador Wilson to Name Names

WASHINGTON - Former Ambassador Joseph C. Wilson will reveal the name of the person he thinks leaked his wife's identity as an undercover CIA officer in a book due out in May, his publisher said Tuesday.

A federal grand jury has heard testimony from at least four White House officials in its investigation to identify the leaker of Valerie Plame's name to syndicated columnist Robert Novak, who published the name in his syndicated column last July. Numerous other officials have been interviewed by the FBI.

Spokeswoman Karen Auerbach of the Avalon Publishing Group in New York said she did not know the identity of the purported leaker.

Novak said in his July 14 column that his sources were two unidentified senior administration officials. Novak has not commented about the matter during the grand jury investigation.

Wilson's book, "The Politics of Truth," is scheduled to come out May 20.
