Rudy Giuliani's associate who helped him dig up dirt on the Bidens is expected to plead guilty in a federal case

• Giuliani associate Igor Fruman is expected to plead guilty in a federal case against him.
• He was charged with campaign-finance violations, conspiracy, false statements, and falsifying records.
• It's not immediately clear which charge or charges he'll plead guilty to.

Former New York mayor Rudy Giuliani's Ukrainian-born business associate, Igor Fruman, is expected to plead guilty in a federal case against him.

Fruman will appear at a change of plea hearing in a Manhattan federal court on Wednesday afternoon, but the charge or charges he will plead guilty to are not immediately clear.

Fruman and his associates, Lev Parnas, David Correia, and Andrey Kukushkin, were arrested in October 2019 and charged with campaign-finance violations, conspiracy, making false statements to the Federal Election Commission, and falsifying records.

A superseding indictment filed last September additionally charged the defendants with conspiracy to commit wire fraud.

Correia pleaded guilty to two of those charges - defrauding investors and making false statements to the Federal Election Commission - last year and was sentenced in February to one year in prison.

Fruman and Parnas made headlines shortly before their arrest when it surfaced that they were under federal criminal investigation related to their work for Giuliani. In particular, the two men aided Giuliani in his quest to dig up dirt on Joe and Hunter Biden in Ukraine. They were also involved in Giuliani and then President Donald Trump's effort to oust Marie Yovanovitch, the US's ambassador to Ukraine.

Giuliani's work in Ukraine connected to US domestic politics was a central pillar in Trump's first impeachment inquiry, after which the House of Representatives impeached him for abuse of power and obstruction of Congress.
