Tell Manafort how unsuccessful the Mueller witch hunt was
Manafort was just one of the many crooks who happen to work in the American political system, there is no avoiding inadvertently hiring some when you end up POTUS. Pretty much every Democrat has people working for them who'd have their corruption uncovered in the same fashion if they were investigated as much as Trump was.
Bottom line is that Russian collusion conspiracy theory was a HOAX, and the D's should be ashamed of wasting away the country's focus on their butthurt-induced conspiracy theory. Many many voters in the middle disapprove of the Democrat Party's shenanigans, and we'll see the consequences of that next November.
So why did Trump work with Manafort BEFORE becoming PotUS? He said he was better at reading people than anybody else...
