Biden–Ukraine conspiracy theory

Joe Biden is falsely alleged to have, as vice president of the United States (2009–2017), withheld a loan guarantee and taken a bribe to pressure Ukraine into firing prosecutor general Viktor Shokin to prevent a corruption investigation of Ukrainian gas company Burisma and to protect his son Hunter Biden, who was on the Burisma board. As part of efforts by Donald Trump and his campaign in the Trump–Ukraine scandal, which led to Trump's first impeachment, these falsehoods were spread in an attempt to damage Joe Biden's reputation and chances during the 2020 presidential campaign, and later in an effort to impeach him.
