The Washington Post originally reported that nearly 150 FBI agents were investigating Hillary Clinton's email account and that certainly would have been extraordinary if it were true.
The Post issued a correction the following day and said the number of agents on the case is actually closer to 50 or about one third of their original report, but NBC now says the number is closer to 12, not 50.
"There are currently about 12 FBI agents working full-time on the case," says the source, who would only speak anonymously about an open investigation. [...]
"147 was such a ridiculous number," said the source, adding that 50 also sounded unrealistic for this kind of inquiry. "You need an act of terrorism to get 50 agents working on something," said the former FBI official.
Both the Washington Post and NBC News have relied on anonymous sources for their reports so it's hard to say who's right. Personally, I find the NBC report to be more believable. Devoting 50 agents to investigating an email account would be an extraordinary waste of resources. Assigning that many agents to a case like this would probably spark committee hearings of its own if Republicans weren't so politically invested in the witch hunt.
We may never know who these anonymous sources are, but I suspect the source who originally told the Washington Post that nearly 150 agents were working the case was someone sitting on or close to the Select Benghazi Committee. This would hardly be the first time a leak from the Bullshit Committee turned out to be a lie.
Come to think of it, I can't recall a single time when a leak from the committee turned out to be true.
