They have the bank records of all the shell companies Hunter and his uncle set up with millions of dollars passing threw from foreign entities with no information on what legitimate reason this money was paid. What product are the Biden's selling? What service?
They have payments directly to Joe Biden with the notation of loan repayment. The problem is there is no record of loans being made or bank records of the loan being deposited in any account all they have is the supposed repayment.
As a former bank auditor I can tell you any first year banker would recognize all the shell company accounts are obviously set up to launder dirty money.
Until you can tell me what the Biden's did to earn 10's of millions of dollars from foreign adversaries like the Chinese and Russians then the only conclusion is they are filthy dirty criminals selling access to Joe Biden and he was in on it.
