Richard L. Armitage, a former deputy secretary of state, has acknowledged that he was the person whose conversation with a columnist in 2003 prompted a long, politically laden criminal investigation in what became known as the C.I.A. leak case, a lawyer involved in the case said on Tuesday.

Mr. Armitage did not return calls for comment. But the lawyer and other associates of Mr. Armitage have said he has confirmed that he was the initial and primary source for the columnist, Robert D. Novak, whose column of July 14, 2003, identified Valerie Wilson as a Central Intelligence Agency officer.
