Osachuk was known for a series of controversial statements and measures, such as the denial of the Fântâna Albă massacre and the removal from the Central Square of Chernivtsi of a banner that reproduced the first documentary attestation of the city, issued by the Moldavian ruler Alexandru cel Bun.[4] [5] Due to this, the Romanian press labeled him as anti-Romanian.[6]
