(Reuters) - Igor Fruman, a former associate of Rudolph Giuliani, told a New York court hearing on Friday he will plead guilty to one criminal count in a campaign finance case.

Fruman worked to collect damaging information about Joe Biden before he became president. Giuliani, a one-time lawyer for former President Donald Trump, has not been charged with criminal wrongdoing although he is under federal investigation in the Southern District of New York.
