Article Two of the U.S. Constitution states “The President, Vice President, and all civil officers of the United States, shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanors.”
The current impeachment inquiry by the U.S. House of Representatives against President Trump is focusing on the allegation he tried to bribe and/or extort President Zelensky of Ukraine to investigate the Bidens in the runup to the 2020 election in exchange for $400 million in foreign aid to Ukraine. The investigation of the Bidens did not occur and the $400 million in aid was subsequently given to Ukraine. Therefore no bribery or extortion occurred.
