A Washington federal judge on Tuesday refused to dismiss the criminal charges against former Donald Trump campaign chairman Paul Manafort, ruling that the “indictment falls squarely within” the authority given to the special counsel for the investigation of Russian interference in the 2016 election.

U.S. District Judge Amy Berman Jackson of the District of Columbia rejected Manafort’s argument that the scope of special counsel Robert Mueller’s authority was overly broad. Manafort was indicted in October on charges of financial fraud and violating lobbying disclosure laws by failing to register his past work for the Russia-backed government of Ukraine.
