President Trump's former campaign chairman, Paul Manafort, has filed a lawsuit challenging the authority of special counsel Robert Mueller.
In a court filing, lawyers for Manafort argue that the order establishing Mueller's investigation is overly broad and not permitted under Justice Department regulations.
"The investigation of Mr. Manafort is completely unmoored from the Special Counsel’s original jurisdiction to investigate ‘any links and/or coordination between the Russian government and individuals associated with the campaign of President Donald Trump,’" the complaint reads. "It has instead focused on unrelated, decade-old business dealings — specifically, Ukraine political campaign consulting activities of Mr. Manafort."
Manafort pleaded guilty to multiple counts in October, including conspiracy against the United States and money laundering related to his work for a pro-Russia political party in Ukraine.
