In an interview, Yuri Lutsenko said while he was Ukraine’s prosecutor general he told Rudolph W. Giuliani that he would be happy to cooperate if the FBI or other U.S. authorities began their own investigation of the former vice president and his son Hunter but insisted they had not broken any Ukrainian laws to his knowledge.
Lutsenko, who was fired as prosecutor general last month, said he had urged Giuliani to launch a U.S. inquiry and go to court if he had any evidence but not to use Ukraine to conduct a political vendetta that could affect the U.S. election.
