[O]ne of [Biden's] most memorable performances came on a trip to Kiev in March 2016, when he threatened to withhold $1 billion in United States loan guarantees if Ukraine’s leaders did not dismiss the country’s top prosecutor, who had been accused of turning a blind eye to corruption in his own office and among the political elite.
