Ответы на Ваши вопросы я приведу так, как они даны в двух статьях, на которые ссылался.
Кто такой "какой-то Касько": в то время - глава международно-правового управления генпрокуратуры Украины:
"By 20 May 2014, Gould had obtained 6,170 electronic documents from BNP Paribas related to Zlochevsky’s money, and assembled a special team to examine them. He also wanted evidence from Ukraine, so he wrote to the head of the international department of the general prosecutors’ office, Vitaly Kasko, in Kiev."
Кстати, тут же и "конец апреля", когда был направлен запрос: не ранее 20 мая 2014 г. Мелочь, но характеризует отношение к материалу.
О том, как расследовалось дело о Бурисме при Шокине:
"There was no pressure from anyone from the U.S. to close cases against Zlochevsky,” Kasko said in an interview last week. “It was shelved by Ukrainian prosecutors in 2014 and through 2015""
"The case against Zlochevsky and his Burisma Holdings was assigned to Shokin, then a deputy prosecutor. But Shokin and others weren’t pursuing it, according to the internal reports from the Ukrainian prosecutor’s office reviewed by Bloomberg."
По вопросу "кто и когда":
"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."
