Prosecutors allege in total more than $75 million flowed through Manafort's and Gates's offshore accounts that they schemed to hide from U.S. authorities “while enjoying the use of the money."

The original charges against Manafort and Gates included conspiracy against the U.S., conspiracy to launder money, failure to register as agents working on behalf of a foreign government, making false and misleading statements under the Foreign Agents Registration Act, as well as intentionally making false statements in an effort to conceal their crimes against the country.

The new indictment appears to slap on a new charge that Manafort, with Gates's assistance, extracted money from his real estate holdings between 2015 and "at least January 2017" in order to fraudulently secure more than $20 million in loans by misrepresenting Manafort’s financial standing.

The indictment specifically charged Gates with failing to properly disclose to the Treasury Department that he had a financial interest in a foreign country, as well as failure to disclose ownership of overseas bank accounts with more than $10,000 between 2012 and 2014. Manafort is similarly accused of failing to make such disclosures between 2012 and 2015.

Mueller has not charged Gates or Manafort for anything related to their work on Trump’s campaign. But the indictments were widely seen as leverage to force their cooperation as Mueller investigates possible coordination between the Trump campaign and Russia.

Manafort’s time on the Trump campaign intersects with events that are reportedly at the center of the federal investigation.

Mueller in recent weeks has gone on a charging spree, indicting 13 Russian nationals and three Russian entities for extensive efforts to interfere in the 2016 presidential campaign through social media and other elaborate means.

He followed up those charged with a guilty plea from lawyer Alex van der Zwaan, who confessed to lying to federal agents about his conversations with Gates regarding a 2012 report he helped compile for Ukraine’s government.
