What language is this in, talking about Donaldo Trumpo?

Lithuanian, I believe. I took two of the words to a translation site.

Lithuanian would have been my guess on a pop quiz, but no more than a guess.

I was somewhat bemused to see so many Google hits on his name with the o endings. I also saw a page with Donaldas Trumpas. It seemed strange to me that speakers of certain languages couldn’t handle the name without adapting it to their linguistic structures. I know that some writing systems have the vowels embedded with the consonants and so there is no way to write the consonants without them, but why would that apply when writing them in the Roman alphabet instead of, say, Devanagari or Hiragana?
