Elon Musk took part in a phone call between Ukrainian President Volodymyr Zelenskyy and U.S. President-elect Donald Trump after his election victory, a senior Ukrainian official said Friday.

"I confirm it," the presidency official who asked to remain anonymous said, adding that the claim in a report by U.S. news site Axios about the call on Wednesday was accurate.

Musk, the world's richest man, played a major role in the Republican's campaign, spending over $110 million of his personal fortune to help get him elected. Trump has said he aims to include Musk in some form of advisory role in his upcoming government.
