"Manafort's civil case will be dismissed, and his concerns regarding the Special Counsel's investigation will be taken up in the criminal case," the document said.
Manafort's civil lawsuit argued that the Department of Justice, particularly Mueller and Deputy Attorney General Rod Rosenstein, overstepped its authority because the criminal charges were not directly related to the 2016 election or allegations of Russian interference.
Earlier in the day, the US House Intelligence Committee revealed its final judgments on alleged Russian meddling in the 2016 US election campaign and accusations of collusion between Donald Trump's campaign and the Kremlin. According to the results of their investigation, there was no collusion between the then-candidate's campaign and Moscow during the 2016 presidential election.
Mueller has charged Manafort with conspiracy, money-laundering, and acting as an unregistered foreign agent for the Ukrainian government, among other charges. The charges were filed as part of Mueller's investigation into allegations of Russian meddling in the 2016 US election and possible collusion between Moscow and President Donald Trump's campaign team.
Russian officials have repeatedly denied allegations of interference, calling the accusations "absurd." Trump has also denied any collusion between himself and the Kremlin and has called Mueller's investigation a "witch hunt."
