In the past, it’s been difficult to pinpoint the exact number of impeached presidents. According to the U.S. Constitution, impeachment is an act that could lead to the demotion of any public office, according to the House of Representatives website. Presidents can be impeached if they are impeached when the House of Representatives approves articles of impeachment that accuse them of specific crimes. The crimes are corruption, treason, and bribery, among other serious crimes and misdemeanors. The first known impeachment took place in 1868, in which President Andrew Johnson was impeached for being accused of violating the Tenure of Office Act. The founders debated over what types of criminal acts could be impeached and decided on bribery and treason as the most obvious examples. If the impeachment motion was approved After the impeachment vote was passed, the Senate must hold an impeachment trial before deciding to convict or acquit the President. The Senate’s website says that convictions require a two-thirds majority of senators. The year 1998 was the time that Bill Clinton was impeached by the House for obstruction of justice and lying before a grand jury about an action for sexual harassment that was filed against Paula Jones. Clinton was later cleared of both counts. Although some historians believe that the Clinton impeachment was an apolitical tactic, others say it was a genuine attempt to establish the case against Clinton in the eyes of members of the American public. The impeachment was controversial, with a wide-ranging impact on the nation. Three U.S. presidents were impeached, including Donald Trump, in 2019. Furthermore, James Buchanan and Richard Nixon were investigated, but they weren’t impeached in 1860 and 1973-1974, respectively.
