His cover story for investigating corruption is ... investigating corruption.
Joe Biden got caught getting his son a top job in the most corrupt country in the world, while he was Obama's pointman in Ukraine. Then got caught, in Jan 2018, bragging about threatening a Ukraine prosecutor, who was investigating his son, by withholding a Billion in Aid. Prosecutor Shokin should be called as a witness at the impeachment trial.
And yes I doubt you. Yours is nothing but a fantasy lib fill-in-the-blanks scenario. There is Zero evidence Zelensky was ever threatened. Call him as a witness, too.
The Aid was approved on May 23, ... two days before Poroshenko was to leave office.
