In 2018, Joe Biden proudly claimed that he pressured Ukrainian President Petro Poroshenko into firing Prosecutor General Viktor Shokin, who was conducting an investigation into the Ukrainian energy company where his son was a board member. Biden accomplished this by leveraging the threat of withholding a $1 billion US loan guarantee during his trip to Kyiv in December 2015.

During a speech at the Council on Foreign Relations, Biden infamously declared, "I looked at them and said: I'm leaving in six hours. If the prosecutor is not fired, you're not getting the money." He added, "Well, son of a bitch. He got fired."

Viktor Shokin has stated that at the time of his termination in March 2016, he had formulated "specific plans" to investigate Burisma, which “included interrogations and other crime-investigation procedures into all members of the executive board, including Hunter Biden.

Your tax dollars at work, used by then VP Biden to threaten and bribe foreign officials to prevent investigation of his son.

This is not just any investigation. They are preparing for impeachment.

In the entire history of the US, prior to Bill Clinton, there was one impeachment. One, from 1789 to December 1998, almost 200 years. From December 1998 to January, 2021, three impeachments, in a bit over 22 years.

If they impeach Biden, the total would go to 5. Possibly four in a quarter of a century, versus one in two centuries.
