WASHINGTON (Reuters) - Lev Parnas, an indicted Ukrainian-American businessman who has ties to President Donald Trumps personal lawyer, Rudy Giuliani, is now prepared to comply with requests for records and testimony from congressional impeachment investigators, his lawyer told Reuters on Monday. Parnas, who helped Giuliani look for dirt on Trumps political rival, former Vice President Joe Biden, is a key figure in the impeachment inquiry that is examining whether Trump abused his office for personal political gain.
