The Trump–Ukraine scandal was a political scandal that arose primarily from the discovery of U.S. President Donald Trump's attempts to coerce Ukraine into investigating his political rival Joe Biden and thus potentially damage Biden's campaign for the 2020 Democratic Party presidential nomination. Trump enlisted surrogates in and outside his administration,including personal lawyer Rudy Giuliani and Attorney General William Barr,to pressure Ukraine and other governments to cooperate in supporting and legitimizing the bogus Biden–Ukraine conspiracy theory and other conspiracy theories concerning US politics. Trump blocked payment of a congressionally-mandated $400 million military aid package,in an attempt to obtain quid pro quo cooperation from Ukrainian president Volodymyr Zelenskyy. Contacts were established between the White House and government of Ukraine,culminating in a call between Trump and Zelenskyy on July 25,2019.
The inquiry process which preceded the first impeachment of Donald Trump,45th president of the United States,was initiated by then-House Speaker Nancy Pelosi on September 24,2019,after a whistleblower alleged that Donald Trump may have abused the power of the presidency. Trump was accused of withholding military aid as a means of pressuring newly elected president of Ukraine Volodymyr Zelensky to pursue investigations of Joe Biden and his son Hunter and to investigate a conspiracy theory that Ukraine,not Russia,was behind interference in the 2016 presidential election. More than a week after Trump had put a hold on the previously approved aid,he made these requests in a July 25 phone call with the Ukrainian president,which the whistleblower said was intended to help Trump's reelection bid.
