“I did not exert any pressure on them, I could, but I did not,” RIA Novosti quoted Trump as saying.

He also emphasized that he did not offer military assistance to Ukraine in exchange for an investigation into the son of former US Vice President Joe Biden.

“No, I didn’t do this ... I hope you see a transcript of the telephone conversation,” he said.

Earlier, The Wall Street Journal, citing sources, said that Trump, in an interview with Zelensky, was trying to force Kiev to launch an investigation against Biden Jr.

Democrats in Congress began to demand the publication of the contents of the conversation, threatening impeachment.

The head of the Ukrainian Foreign Ministry, Vadim Pristayko, noted that he knew the content of the conversation and “there was no pressure”.
