Shokin became prosecutor general in February 2015. Over the next year, the U.S. and the International Monetary Fund criticized officials for not doing enough to fight corruption in Ukraine.
Shokin took no action to pursue cases against Zlochevsky throughout 2015, said Kasko, who was Shokin’s deputy overseeing international cooperation and helping in asset-recovery investigations. Kasko said he had urged Shokin to pursue the investigations.
The U.S. stepped up its criticism in September 2015, when its ambassador to Ukraine, during a speech,
accused officials working under Shokin of “subverting” the U.K. investigation.
Kasko resigned in February 2016, citing corruption and lawlessness in the prosecutor general’s office.
The U.S. plan to push for Shokin’s dismissal didn’t initially come from Biden, but rather filtered up from officials at the U.S. Embassy in Kiev, according to a person with direct knowledge of the situation. Embassy personnel had called for U.S. loan guarantees to Ukraine to be tied to broader anti-corruption efforts, including Shokin’s dismissal, this person said.
Biden’s threat to withhold $1 billion if Ukraine didn’t crack down on corruption
reportedly came in March. That same month, hundreds of Ukrainians demonstrated outside President Petro Poroshenko’s office demanding Shokin’s resignation, and he was dismissed.
Shokin has denied any accusations of wrongdoing and declined to provide immediate comment for this article. In an
interview with the Ukrainian website Strana.ua published on May 6, Shokin said he believes he was fired because of his Burisma investigation, which he said had been active at the time.
In October 2017, Burisma issued a statement saying Ukrainian prosecutors had closed all legal and criminal proceedings against it.
