According to Jeff Carlson (Epoch Times), the FBI was notified of PapaD-Downer convo on JULY 22/16
JULY 22/16 is also the date that DNC emails were leaked.
THIS was the impetus for the CI investigation?!? Wikileaks releasing very damaging emails?!? It fits - because the info Downer has was that PapaD might have info damaging to HRC.
