Back in July, Sen. Charles Schumer (D-NY) called upon FBI Director Mueller to investigate the source of the leak of CIA operative Valerie Plame's identity. The press release on his Senate website says:

News reports suggest that Administration could have leaked the identity of a CIA agent to discredit a critic of the President and intimidate others from speaking out

US Senator Charles Schumer today asked FBI Director Robert Mueller to open an investigation into reports that two senior members of the Bush Administration illegally disclosed the identity of a Central Intelligence Agency (CIA) operative. According to Section 421a of the Intelligence Identities and Protection Act, the unauthorized identification of a CIA operative is a criminal act punishable by up to ten years in federal prison.

"This is one of the most reckless and nasty things I’ve seen in all my years of government," Schumer said. "Leaking the name of a CIA agent is tantamount to putting a gun to that agent’s head. It compromises her safety and the safety of her loved ones, not to mention those in her network and other operatives she may have dealt with. On top of that, the officials who have done it may have also seriously jeopardized the national security of this nation."

Here is the text of the letter Schumer sent to Mueller. Does anyone know what, if anything, Mueller or the FBI did in response? We suspect the answer is "nothing," but we'll be pleased to learn we are wrong.

Six telephone calls to journalists, all of whom must have told their editors, and possibly colleagues....this should hardly be the mystery of the year. We won't be surprised if by tomorrow morning, some enterprising journalist has uncovered it.
