Giuliani makes some serious allegations against Joe Biden and claims that he has the evidence and witnesses to back it up. If as Giuliani claims the State Department and the DOJ were given this information and they refused to investigate, a special council needs to be started to investigate everyone involved.
While I know the anti Trumpers don't want Biden or the players in the State Department and the DOJ investigated it only makes sense if we want to know the truth. Trump has been investigated by everyone and their dog only to find nothing, now it's time to investigate the ones that perpetrated what looks to be real corruption.
