The US President took to Twitter to announce he would be publishing the details of the conversation he had with Volodymyr Zelensky in the coming days. On October 31 the House of Representatives approved its first resolution related to the impeachment inquiry. Mr Trump tweeted: “I will be releasing the transcript of the first, and therefore more important, phone call with the Ukrainian President before week’s end.”
This week the Democrats will launch the public phase of their impeachment inquiry with open, televised hearings set for Wednesday and Friday in the Democratic-run House.
The inquiry was formally started on September 24.
Lawmakers allege Mr Trump abused his office for personal political gain.
The president’s rivals have been holding hearings with current and former officials behind closed doors and will not take their case to the American public.
They want to build a strong public case that Mr Trump is guilty of an abuse of power for pressuring Ukraine to launch corruption investigations involving the son of Joe Biden.
Mr Biden, who served as vice-president under Barack Obama is the frontrunner in the race for the Democratic nomination ahead of next year’s presidential election.
Democrats want the broadest possible public support should they choose to formally impeach Trump, which could happen by December.
Any trial would take place in the Senate, which is controlled by Trump’s Republican Party.
Trump said on Saturday he would likely release the transcript on Tuesday, describing it to reporters as “very important.”
On Monday he said he would release it this week, adding: “I am sure you will find it tantalising!”
