In a little-noticed court filing earlier this month, federal prosecutors described Steve Bannon as a “co-conspirator” in a massive criminal fraud and racketeering case against a flamboyant, far-right Chinese fugitive, compounding the legal headaches of the former Donald Trump adviser. FBI agents in March 2023 arrested Guo Wengui, a self-styled anti-Chinese government activist Bannon once advised, charging him and two associates with using a series of fraudulent investment opportunities to defraud thousands of Guo’s supporters in the Chinese diaspora of more than $1 billion. Guo used the proceeds to fund a lavish lifestyle for himself and his family, including a $3.5 million Ferrari, a $26 million mansion, a $140,000 piano, and two $36,000 mattresses, the Justice Department alleges.
