Attorneys for President Donald Trump's campaign chairman, Paul Manafort, are reportedly blocking Robert Mueller, the special counsel leading the FBI's Russia investigation, from obtaining a transcript of his interview with the Senate Intelligence Committee in July. CNN reported on Tuesday that a dispute had erupted between the FBI, which said it had obtained authorization from Manafort's attorneys to view the transcript, and the committee, which says it was instructed by the attorneys not to hand it over. Manafort's attorneys' reluctance to allow Mueller to view the transcript, moreover, is likely to raise red flags for the FBI and prompt it to take more aggressive measures to obtain it.
