Special Counsel Robert Mueller levied 32 new charges against Paul Manafort and Rick Gates on Thursday, the latest development in the Justice Department's sprawling probe into Russian interference in the 2016 election. The charges against Manafort, President Trump's former campaign chairman, and Gates, a former campaign aide and Manafort's business associate, include multiple charges of tax and bank fraud.

The indictment, handed down Thursday by a federal grand jury, includes a litany of financial crimes, alleging the men filed false income tax returns and failed to disclose foreign accounts. One specific charge claims that Gates helped Manafort launder "more than $30 million in income," Reuters reported. In October, Manafort and Gates were indicted on 12 counts, including conspiracy against the United States and conspiracy to launder money, in the first round of charges to result from Mueller's probe.

The timing of the Thursday filing is notable, The Washington Post noted, because there is "significant uncertainty in the case about when a trial might happen, or even who the defense lawyers will be." Gates' three lawyers have all asked to be dismissed from the case.

Since October, George Papadopoulos, a former foreign policy adviser to the Trump campaign, and Michael Flynn, Trump's first national security adviser, have pleaded guilty to lying to the FBI. Last week, 13 Russian nationals and three Russian companies — including an infamous "troll farm" known as the Internet Research Agency — were charged with conspiracy for online efforts intended to influence the election, the first charges from Mueller's office that concern election meddling specifically.
