Manafort is charged with tax and bank fraud connected to his lobbying work for the Ukrainian government and pro-Russia interests in Ukraine.
Deputy Attorney General Rod Rosenstein has "rejected the history and integrity of the DOJ, and instead licensed a Special Counsel who for all practical political purposes can not be fired, to indict a case that has absolutely nothing to do with any links or coordination between any candidate and the Russian Government", Concord wrote in its filing, echoing claims made by the Trump administration.
President Donald Trump's attorney Rudy Giuliani has warned Robert Mueller that the Trump team will wage a campaign to end the Special Counsel's Russian Federation investigation on its one-year anniversary, with several plans up their sleeve.
The decision was a setback for Manafort in his defence against charges of money-laundering conspiracy, false statements and acting as an unregistered foreign agent related to his Ukrainian political work.
The special counsel's office declined to comment on Jackson's memorandum opinion.
Judge: Special counsel had authority to prosecute Paul Manafort
In response to these charges, Manafort claimed that he could not be prosecuted by Special Counsel Robert Mueller because the particular charges against him are outside of Mueller's properly delegated authority.
Her ruling also pointed to an August 2017 memo by Deputy Attorney General Rod Rosenstein that detailed the scope of Mueller's investigation.
"Who had connections to the Russian government?"
Following the release of Jackson's opinion, Jason Maloni, a spokesman for Manafort, said, "Paul Manafort maintains his innocence and looks forward to prevailing in this matter". "Given what was being said publicly, the Special Counsel would have been remiss to ignore such an obvious potential link between the Trump campaign and the Russian government", Jackson wrote.
Jackson was not moved by any of Manafort's assertions.
Jackson had previously thrown out a civil case Manafort brought challenging Mueller's authority. Nevertheless, Manafort's claims seemed to take on a new life earlier this month when Judge T.S. Ellis, the judge hearing the remaining charges against Mueller, asked some skeptical questions about Mueller's authority during a recent hearing. "For all of these reasons, the motion to dismiss is denied".
