Former Giuliani associate disputes GOP claims of Biden wrongdoing in Ukraine

Lev Parnas, ex-Giuliani associate, says he found no evidence of illegal activity by Hunter or Joe Biden related to Ukraine.
Parnas claims he and Giuliani unsuccessfully pressured Ukraine for damaging information about the Bidens.
Parnas offers to testify to Congress that accusations against the Bidens are false.
House Oversight Chair James Comer continues investigation into alleged $5 million Biden bribe despite lack of evidence.
Parnas urges Republicans to abandon their investigation into the Bidens regarding Ukraine as a "wild goose chase."
