Because of his background in foreign affairs, Joe Biden was tasked by then President Obama with overseeing America’s foreign policy. Joe Biden relished the assignment and took deep personal interest in countries such as Ukraine, Russia, and China.
He pressured Ukrainian government officials to have the prosecutor fired. This he did by threatening to withhold one billion dollars in US aid which had been promised by Barrack Obama. After some resistance the Ukrainian government officials caved in and fired the prosecutor. Joe Biden later boasted about it in a talk which was recorded on video.
But rather than advancing the interests of the United States, the Bidens used Ukraine - and other countries - to enrich themselves through brazen influence peddling schemes. Hunter Biden was paid, for example - one million dollars a year - by a shady gas and oil Ukrainian company called Burisma..
