I'm aware. Most of the nation is bilingual, and they didn't mind speaking Russian until oh I don't know, I guess something happened. Depending on her views and how long ago the interview was, chances are it's still in Russian. Not to mention that the languages have about 60-70% common language base, and about 30% of Russians have Ukrainian family relations, whether either side likes it or not. Even if the interview is in full Ukrainian, it should be quite discernable still.
