I am referring specifically to reports that the CIA ex-filtrated Oleg Smolenkov, a mid-level Russian Foreign Ministry bureaucrat who has hooked himself on the coat-tails of Yuri Ushakov, who was Ambassador to the US from 1999 through 2008. He was recruited by the CIA (i.e., asked to collect information and pass it to the U.S. Government via his or her case officer) at sometime during this period. A supposedly "sensitive" source. He was not. But you would not necessarily glean this fact if you read either the Washington Post or New York Times accounts of this event.
This is the kind of source that helps a CIA case officer get promoted but adds little to actual U.S. intelligence on Russia. If you understood the CIA culture you would immediately recognize that a case officer (CIA terminology for the operations officer tasked with identifying and recruiting human sources) gets rewarded by recruiting persons who ostensibly will have access to information the CIA has identified as a priority target. In this case, we're talking about possible access to Vladimir Putin.
