2019 Trump–Ukraine scandal - Wikipedia
The 2019 Trump–Ukraine political scandal 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 Biden–Ukraine conspiracy theory and other conspiracy theories concerning U.S. politics.[1][2][3][4][5] 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 phone call between Trump and Zelenskyy on July 25, 2019.
The White House corroborated allegations raised by the whistleblower. A transcript of the Trump–Zelenskyy call confirmed Trump requested investigations into Joe Biden and his son Hunter Biden, as well as a conspiracy theory involving a Democratic National Committee server, while urging Zelenskyy to work with Giuliani and Barr on this.
Former acting chief of staff Mick Mulvaney said one reason why Trump withheld aid to Ukraine was Ukrainian "corruption related to the DNC server", referring to a debunked theory that Ukrainians framed Russia for hacking into the DNC system.[12] Trump has publicly urged Ukraine and China to investigate the Bidens.[13] The Trump administration's top diplomat to Ukraine, Bill Taylor, testified he was told aid to Ukraine and a Trump–Zelenskyy White House meeting were conditional on Zelenskyy announcing investigations into the Bidens and alleged Ukrainian interference in the 2016 U.S. elections.
Trump was impeached on charges of abuse of power and obstruction of Congress,[18] but was acquitted by the Senate.
