He was in business with Roger Stone and he worked with Trump for nearly thirty years. He's been in business with unsavory tyrants all over the world. Many of them laundered money through New York City. There is a great deal of suspicion that up to 1600 apartment owned by Trump were used to launder Russian mafia money. Mueller most likely can get Manafort to give him Roger Stone. Stone is suspected of being the go between for Wikileaks/Putin(the GRU)/Team Trump for the hacked emails and information used to target certain voters. Remember, we're in a place where Trumpian propaganda and talk show hosts presenting sophistries no longer matter. Attacking others as Never Trumpers when you hear things you don't want to hear doesn't work in courts. Witches are going on the endangered species list. For Mueller, there are these felony convictions: 1) Mike Flynn 2) George Papadopoulos 3) Rick Gates 4) Michael Cohen 5) Paul Manafort.
Principled and thoughtful conservatives must ask themselves these questions. Why did we trust Trump? Why didn't we see that he had a sordid biography? Why did we decide that character did not matter? Why do we still pretend that everything is fine?
Trump's pick of Manafort was identified immediately as a dangerous act. None of this was unforeseeable. We need to see with our eyes and act like the truth still matters. Or allow Trump to ruin the conservative movement. The rule of law still matters. Trump's tweets won't save him.
