No, I believe Hunter is a crook because there's a pile of evidence he's a crook. Even his ex-business partners say he's a crook. We know for absolutely sure that daddy Joe met with Hunter's business partners and associates he was doing business with on numerous occasions. We know that Hunter was present in some cases. There are e-mails, records, and photographs that prove it. Yet Joe still maintains he never had anything to do with Hunter's business dealings. That is an obvious and clear lie based on what we do know about those things.
On the other hand, right now, you have a single female ex-staffer making claims against Guiliani and Trump without any physical evidence to back them up. Maybe she's got something but that's yet to be seen.
This thread is about Trump and Rudy Giuliani selling pardons, and not Hunter Biden.
