After leaving the office of the Vice President, Joe Biden said, "I said, I’m telling you, you’re not getting the billion dollars. I said, you’re not getting the billion. I’m going to be leaving here in, I think it was about six hours. I looked at them and said: I’m leaving in six hours. If the prosecutor is not fired, you’re not getting the money. Well, son of a bitch. (Laughter.) He got fired."

The fired prosecutor was the Ukrainian prosecutor general, Viktor Shokin.

Joe Biden's son, Hunter Biden, was a board member of a Ukrainian company, Burisma Holdings.

Did Joe Biden threaten to withhold these funds in order to protect his son from investigation or prosecution?
