David Correia and Andrey Kukushkin, the co-defendants charged alongside two foreign-born associates of Rudy Giuliani in a scheme to violate American campaign-finance laws, pleaded not guilty Thursday in Manhattan federal court.

Both men were charged last week on on -count of conspiracy in a four-count indictment linked to Lev Parnas and Igor Fruman, who prosecutors said conspired to funnel foreign money into U.S. elections in order to buy influence among lawmakers in state and federal governments.

Correia, who surrendered to authorities Wednesday, is currently out on $250,000 bail. He is represented by William Harrington of Goodwin Procter.

Kukushkin, meanwhile, agreed to the terms of his $1 million bail package and walked out of the Manhattan federal courthouse with his attorney, Gerald Lefcourt of Gerald B. Lefcourt P.C.

Parnas and Fruman were set to be arraigned Oct. 23. Fruman was released Wednesday from federal custody, but Parnas remained in the Eastern District of Virginia on Thursday, until he could meet the terms of his bail package.

The next court date for all four defendants was set for Dec. 2 before U.S. District Judge J. Paul Oetken of the Southern District of New York.

Assistant U.S. Attorney Nicolas Roos said he expected the Justice Department to produce "fairly voluminous" discovery materials, including 10 search warrant applications, electronic records from more than 10 email accounts and financial records from more than 50 bank accounts.

"I think it's fair to characterize the government's investigation as ongoing," he told Oetken.

Roos did not say whether prosecutors planned to file additional charges or a superseding indictment in the case.

Prosecutors alleged last week in a 21-indictment that Parnas and Fruman made illegal donations to a pro-Trump super PAC and former U.S. Rep. Pete Sessions, R-Texas. The pair then worked to conceal their scheme from candidates, campaigns and federal regulators by laundering money through bank accounts in the names of limited liability companies and through the use of straw donors, according to the indictment.

Fruman and Parnas are reported to have close business ties to Giuliani, the former New York mayor turned personal attorney to President Donald Trump. The indictment did not mention Giuliani or allege that he had any involvement in the alleged crimes.
