Ukrainian opposition lawmaker Oleksiy Goncharenko has filed an official request for President Volodymyr Zelenskiy's office to release a full transcript of Zelenskiy's July call with President Donald Trump, Interfax Ukraine said Thursday.

According to a summary of the telephone call released by the Trump administration on Wednesday, Trump pressed Zelenskiy to investigate a political rival, former Democratic Vice President Joe Biden.

Goncharenko wants a full transcript, translated into Ukrainian, Interfax said, citing a Facebook post where Goncharenko had also pasted a scanned copy of his request. Zelenskiy's office would not immediately comment.
