The State Bureau of Investigation (SBI) has said Ukrainian President Volodymyr Zelensky's ex-chief of staff Andriy Bohdan during his questioning on September 14 provided no confirmation or evidence of possible wrongdoings on part of Ukrainian officials in favor of "another state."
In a commentary, SBI said summoning Bohdan for questioning came after the latter claimed in an interview relased earlier about possible wrongful contacts of Ukrainian officials with the Russian government.
