New Developments in the Valerie Plame Case

Mr. Armitage knew about Ms. Wilson’s C.I.A. role only because of a memorandum that Mr. Libby had commissioned as part of an effort to rebut criticism of the White House by her husband, Joseph C. Wilson IV.

her identity had been disclosed in the Novak column as part of a campaign to undermine her husband.

Mr. Armitage spoke with Mr. Novak on July 8, 2003, those familiar with Mr. Armitage’s actions said. Mr. Armitage did not know Mr. Novak, but agreed to meet with the columnist as a favor for a mutual friend, Kenneth M. Duberstein, a White House chief of staff during Ronald Reagan’s administration. At the conclusion of a general foreign policy discussion, Mr. Armitage said in reply to a question that Ms. Wilson might have had a role in arranging her husband’s trip to Niger.

At the time of the offhand conversation about the Niger trip, Mr. Armitage was not aware of Ms. Wilson’s undercover status, those familiar with his actions said. The mention of Ms. Wilson was brief. Mr. Armitage did not believe he used her name, those aware of his actions said.

On Oct. 1, 2003, Mr. Armitage was up at 4 a.m. for a predawn workout when he read a second article by Mr. Novak in which he described his primary source for his earlier column about Ms. Wilson as “no partisan gunslinger.” Mr. Armitage realized with alarm that that could only be a reference to him, according to people familiar with his role. He waited until Secretary of State Colin L. Powell, an old friend, was awake, then telephoned him. They discussed the matter with the top State Department lawyer, William H. Taft IV.

Mr. Armitage had prepared a resignation letter, his associates said. But he stayed on the job because State Department officials advised that his sudden departure could lead to the disclosure of his role in the leak, the people aware of his actions said.

But Mr. Fitzgerald did obtain the indictment of Mr. Libby on charges that he had untruthfully testified to a grand jury and federal agents when he said he learned about Ms. Wilson’s role at the C.I.A. from reporters rather than from several officials, including Mr. Cheney.
