NBC news this on-air commentary by John Siegenthaler during Nightly News just now:
"More tonight on the investigation into the leak of a CIA agent, Valerie Plame. Prosecutors had subpoenaed NBC's News' Tim Russert, and NBC had gone to court to block the subpoena.
As reported previously, Russert was not a recipient of the leak.
Today, Russert was interviewed under oath by the Special Prosecutor, and was not asked any questions that would require him to disclose information provided in confidence.
The questioning focused on what Russert said when Lewis "Scooter" Libby, VP's Chief of Staff, phoned him last summer. Russert testified that at the time of the conversation, Russert didn't know Plame's name or that she was a CIA operative, and he didn't provide that information to Libby. He said that the first time he learned the information was when he later read a column by Robert Novak.
(as close to verbatim as i can get)
Libby seems to be the target of the investigation.
But a bit strange to me that they think a member of the press may have passed the information to the administration.
Or am I reading this wrong? Hopefully someone else has followed this more closely.
