Been watching CNN to observe their coverage, They had an analyst on who seemed to be on top of the story. The CNN talking head actually attacked him a bit asking why he was bringing up additional issues and how he knows what he knows.
According to him he received the information from people in the FBI who are actively involved with the case. He said that when the team of agents found the information during the Weiner investigation those agents went and discussed what they found with the team of agents that worked Hillary’s email investigation. Those agents then said this is definitely something we want to look into. The result was Comey’s letter.
He also said there is still an ongoing investigation with the Clinton foundation and what they just found has now become a source of information for three separate investigations.
That’s encouraging, at least it’s an indication that there’s still honest people in the FBI that are willing to speak up.
