On May 11 the Security Service of Ukraine (SBU) conducted a search of the Kyiv home of Viktor Medvedchuk, a Ukrainian oligarch, politician and millionaire who is widely regarded to be sympathetic to Russian President Vladimir Putin. Mr. Putin is, after all, godfather to Mr. Medvedchuk’s daughter and Mr. Medvedchuk has long been known to harbor sympathy for the Kremlin even before Ukraine’s ongoing war against pro-Russian and Russian-backed separatists began in the east of the country.
