Special Counsel Robert Mueller’s team of prosecutors is reportedly growing frustrated with Paul Manafort’s level of cooperation, even though he agreed to provide them with a “broad” range of information as part of his September plea deal. According to ABC News, the former Trump campaign chairman has met with prosecutors nearly a dozen times, but they are “not getting what they want.” If he is found not to be cooperating with the terms of the deal, Manafort could face additionl fines or an extended prison sentence. Manafort is currently sitting in a Virginia jail “awaiting his sentencing on a host of charges brought by Mueller’s prosecutors in two separate jurisdictions as part of his investigation into Russian meddling during the 2016 campaign,” ABC News reported. In August, Manafort was convicted in Virginia on bank and tax fraud charges and will be sentenced in February, and he pleaded guilty to two counts of conspiracy in Washington, D.C., as part of the deal. It’s not clear exactly what information Mueller’s team is seeking, but ABC News sources claim they are interested in talking to Manafort about his history with Roger Stone, another focus of the Mueller probe and Manafort’s one-time partner at the lobbying firm Black, Manafort, Stone, and Kelly. Manafort is talking to the special counsel “about a lot of things, none of which are incriminating with regard to the president,” Trump lawyer Rudy Giuliani told Reuters last month.
