President Donald Trump's former campaign manager, Paul Manafort, was hit with additional charges in Special Counsel Robert Mueller's probe of the 2016 election.

The 32 new charges include bank fraud and filing false tax returns. The indictment was filed in the U.S. District Court for the Eastern District of Virginia.

Mueller's move follows last week's indictment of 13 Russian nationals and three Russian entities, with the special counsel's office alleging those nationals and entities interfered in the 2016 election to support Trump.

Manafort and his associate, Richard Gates, surrendered to federal authorities in October 2017 on charges arising from their work as paid lobbyists for Ukraine and its former president, Viktor Yanukovych — a fact they allegedly hid from U.S. authorities.

The October indictment charged that Manafort set up offshore accounts through which $75 million was funneled. Of that amount, about $18 million was laundered to hide it from the IRS and U.S. Justice Department, prosecutors charged. That indictment was filed in the U.S. District Court for the District of Columbia.

The Manhattan district attorney's office subpoenaed records of loans made to Manafort by Chicago-based Federal Savings Bank in July of 2017, according to a Wall Street Journal report. The bank, which was not mentioned in the most recent indictment, loaned up to $16 million to Manafort and his wife, Kathleen.

The special counsel's investigation has already produced guilty pleas from Michael Flynn, Trump's former national security adviser and George Papadopoulos, another campaign adviser.
