Was this before or after Joe Biden held back the billion dollars unless they fired the prosecutor who was investigating his son?
1. The prosecutor was
NOT investigating Biden's son.
2. Biden was sent by NATO, the International Monetary Fund, the European Union and the Obama Administration to tell the Ukrainians that NO ONE from any of those organizations would be giving the Ukraine aid until they started dealing with corruption. All of this public at the time, and all of it was debated in Congress and the Senate.
In extorting the Ukraine, Trump was acting for his own benefit for political reasons, and in a secret manner, to thwart the aid to the Ukraine that was voted for overwhelmingly by a by-partisan vote in both Houses of Congress. Then he tried to cover up what he did.
At every step along the way what Biden did was open, above board, and based on him working on behalf of the country. Contrasted with Trump and his staff hiding the reasons why Trump was withholding funds from the Ukraine, when State Department contractors hired by Trump, were pressuring for those investigations behind the scenes.
I found it sad that President Zelensky is still asking Trump for that invitation to the White House, and that he's been dragged into all of this.
