A business partner of Lev Parnas, who helped Rudolph W. Giuliani, President Trump’s personal lawyer, dig up dirt on the president’s political rivals is expected to plead guilty on Thursday to defrauding investors in a start-up, according to two people with knowledge of the case.
The partner, David Correia, will admit in Manhattan federal court to duping investors in a company he founded with Mr. Parnas, Fraud Guarantee, that offered a kind of insurance against swindles, one of the people said.
Mr. Correia, who was a peripheral player in the president’s impeachment drama, is not expected to cooperate with Manhattan federal prosecutors in an examination of Mr. Giuliani and Mr. Parnas’s efforts in Ukraine to discredit former Vice President Joseph R. Biden Jr.
Mr. Correia and Mr. Parnas were indicted in October 2019 on federal campaign finance charges, accused of hiding the source of money they had donated to Mr. Trump. New charges filed last month accused the men of duping their investors in Fraud Guarantee.
Mr. Correia is also expected to plead guilty to making a false statement to the Federal Election Commission in connection with the campaign donation.
Mr. Parnas, who has since broken with Mr. Giuliani and Mr. Trump, has pleaded not guilty.
