Sen. Pat Roberts, R-Kan., who now heads the Senate Intelligence Committee, declined to elaborate further on the details but said he would participate "whenever this does come up," the paper said Monday.
He had earlier suggested he would recuse himself from the inquiry because he was a member of the Intelligence Committee in June 2002 when the leak is said to have occurred. Roberts said he decided to participate because his experience will help other Senate Ethics members -- none of whom is on Intelligence -- navigate the sometimes arcane waters of classified information.
Press accounts that appeared at the time of the alleged leak involving an intercepted wireless telephone call suggested Shelby was the source. Another member of the committee who requested anonymity said the Ethics panel should not focus solely on Shelby. "It's not necessarily limited to one person, in my judgment," the unidentified senator said.
Shelby has denied knowingly revealing classified information at any time during his eight years on the secretive committee, including during his years as its chairman.
