I don't know if this has been posted, but this is a great piece by Jeff Carlson about the common thread found in 4 ongoing investigations…
*There appears to be a common thread amongst on unrelated events: the raid on the whistleblower, the raid on the Chicago politician, the investigations of European banks, and the charges brought against a Clinton donor. All the activities targeted were either occurring under the Obama era or, in the case of the DOJ whistleblower, were directly related to underlying events from that time.
There may be more going on than meets the casual eye.*
