KYIV -- Ukrainian Deputy Prosecutor-General Vitaliy Kasko, known for his pro-reform stance, has resigned.
Kasko told journalists in Kyiv on February 15 that "the straw that broke the camel's back" was a move by Prosecutor-General Viktor Shokin to take all of Kasko's activities under his control.
"The Prosecutor-General's Office today is a dead institution, in independence and efficiency, that nobody believes in anymore," Kasko said.
U.S. Ambassador to Ukraine Geoffrey Pyatt wrote on Twitter after Kasko's announcement that "Kasko was a champion of reforms in the prosecutor-general's office in Ukraine. His resignation will interrupt the progress of reforms in Ukraine."
Earlier in February, another reformist member of the government, Aivaras Abromavicius, resigned from the post of economy minister.
Abromavicius said his resignation was borne out of frustration over the "sharp escalation in efforts to block systemic and important reforms."
