ANDREW MCCARTHY: A Watergate-style Scandal.

In general, it is the FBI that conducts investigations that bear on American citizens suspected of committing crimes or of acting as agents of foreign powers. In the matter of alleged Russian meddling, the investigative camp also includes the CIA and the NSA. All three agencies conducted a probe and issued a joint report in January. That was after Obama, despite having previously acknowledged that the Russian activity was inconsequential, suddenly made a great show of ordering an inquiry and issuing sanctions.

Consequently, if unmasking was relevant to the Russia investigation, it would have been done by those three agencies. And if it had been critical to know the identities of Americans caught up in other foreign intelligence efforts, the agencies that collect the information and conduct investigations would have unmasked it. Because they are the agencies that collect and refine intelligence “products” for the rest of the “intelligence community,” they are responsible for any unmasking; and they do it under “minimization” standards that FBI Director James Comey, in recent congressional testimony, described as “obsessive” in their determination to protect the identities and privacy of Americans.

Understand: There would have been no intelligence need for Susan Rice to ask for identities to be unmasked. If there had been a real need to reveal the identities — an intelligence need based on American interests — the unmasking would have been done by the investigating agencies.

The national-security adviser is not an investigator. She is a White House staffer. The president’s staff is a consumer of intelligence, not a generator or collector of it. If Susan Rice was unmasking Americans, it was not to fulfill an intelligence need based on American interests; it was to fulfill a political desire based on Democratic-party interests.

I’m so old I can remember when the Obama Administration was “amazingly scandal-free.”
