Paul Manafort, President Trump's former campaign chief, pleaded not guilty Wednesday to vast money laundering conspiracy and fraud charges as a federal judge set the stage for a trial to begin Sept. 17. Manafort appeared for the first time in federal court since his campaign deputy Rick Gates pleaded guilty Friday to related charges and agreed to cooperate with the government’s prosecution of Gates’ longtime business partner. Manafort was required to appear Wednesday to enter a new plea to a revamped five-count indictment issued Friday.
