Trump's presidential pardon power does not extend to state crimes. Manafort was tried and convicted by the State of New York,.. Manafort has a second trial in September facing Federal Charges, if found guilty there, Trump could then pardon Manafort's Federal convictions. http://thehill.com/blogs/pundits-blog/the-administration/348989-trump-may-dodge-federal-crimes-with-pardons-but-he-cant
Not quite right Duck. Manafort was convicted in US Federal court and his next trial is in federal court. However you’re right he is facing trial in NY state court. Assuming the great volume of evidence against him is there he’ll be spending quite a few years in Sing-Sing.
