yes they did. Investigations have to start somewhere, and they used it as a template. If that was as far as they got-Wait a few news cycles. It's now apparent that the anti Clinton wing of the FBI used the Breitbart book 'Clinton Cash' as a source of evidence for their investigation. It's no wonder they were laughed out of the meeting with the DOJ when the Clinton Foundation investigation was first hatched.
The days leading up to Election Day will be very good for the Clinton campaign

it would have stayed a preliminary inquiry.
But from all we know this is an INVESTIGATION going on for a year, despite DoJ obstructing grand juries, etc.
Now they are doing re-interviews.
Looks like a real investigation to me.
