A summary of the telephone call in April when Trump congratulated Zelenskiy for winning the Ukrainian presidential election, announced by the White House on November 15.

During a phone call on April 21, Zelenskiy invited the US president to the inauguration ceremony, but Trump said he wanted to invite the new president of Ukraine to visit the White House. Trump said he admired Ukraine and praised the country for having excellent contestants to join Miss Universe, but did not mention the father and son of former US Vice President Joe Biden.

The US House of Representatives opened an impeachment investigation against Trump after an anonymous whistleblower accused Trump of urging Ukraine to investigate Joe Biden. Trump said Joe Biden used his power in office to help Ukraine Burisma company not be investigated for corruption. Joe Biden's son Hunter Biden worked at Burisma during this time.

The summary of Trump and Zelenskiy's April phone call was not a tape recording, but a reconstruction based on shorthand notes. "We have many issues to discuss but we are always with you," Trump's statement was transcribed in the note.

The first public hearing in Trump's impeachment investigation was broadcast live on November 13, attracting 13 million viewers. During the hearing, two witnesses, former US ambassador to Ukraine Bill Taylor and Deputy Assistant Secretary of State George Kent revealed some new details related to the alleged Trump pressure on Ukraine.

Democrats hope the live broadcast of the hearing will make the public support the Trump impeachment investigation. But many US voters say they continue to support Trump and call the impeachment investigation a Democratic party effort to topple people they could not defeat in 2016.

Trump has repeatedly called the US House of Representatives investigating his impeachment as a "joke" and "witch hunt". The US president said he did not watch the live broadcast of the first hearing because he was too busy.
