Prior to his expulsion, Radojičić was a member of Dveri's presidency and represented the party at international events. He was an international observer for the controversial 2014 referendum on the status of Crimea, which he described as well-organized and free of coercion. He took part in a Dveri delegation to the disputed Republic of Crimea the following year; Ukraine, which considers Crimea to be under its jurisdiction, responded by initiating criminal proceedings against Radojičić and the other delegates.
