So former Trump aid Rick Gates has just pleaded guilty to conspiracy and lying to the FBI. Gates along with Manafort were previously charged. Gates has decided to join Michael Flynn and Papadoplous and plead guilty and work with Mueller instead of do the time (or as much time).
So next up is Manafort. With Gates flipping, this puts more pressure on Manafort to do the same. After that, there is really only one higher target, Donald "The Russian Puppet" Trump. The sooner this happens, the better, but we must let Mueller continue as he sees fit. He knows this game and he knows the stakes are high. We cannot let the traitor continue to sit in the Oval Office.
