I understand that Trumps last defense against impeachment is going to be proving that there was legit corruption with the Biden/Ukraine situation. Problem is there is no evidence of laws being broken and this is a thing of the past that was out in the open. To me it is obviously a bad PR situation that Trump was looking to exploit in next years campaign. To those who think it’s a legit concern... what exactly is left to be discovered about Hunter Biden’s board seat at Burisma? Can somebody explain what they are looking for? Or what questions are still unanswered?
