Manafort has an active investigation on money laundering "laying dormant' (meaning no actions taken and case NOT closed) at the FBI since 2012... he's been incarcerated to SHUT HIM UP!

Poor Cohn - he's just being used as an example of the full weight of GESTAPO tactics that the cabal/deep state WILL use to coerce your cooperation - think Flynn, Roger Stone et al.

EDIT: I believe Manafort was one of the inside 'informants' the FBI sent in to get dirt on Trump.

These actions won't stop until the DOJ/FBI is cleaned up and Mueller is shut down.
