In theory political opponents shouldn’t have to do the exposing of corruption. It should have been done long time ago by the FBI or AG during the time of the Obama regime. But they thought it healthier not to see at that time. Likewise with Clinton corruption. Now they are going after Trump for exposing Biden family corruption. Trump is like a Teflon coated eel, so strangling him will be very difficult and will most likely not happen. Biden has already lost the primary, I bet he mainly stay in the race to maintain his “untouchable” “political opponent” status.
