An impeachment inquiry is a formal process used by a legislative body, such as the U.S. Congress, to investigate whether a public official, like the President, should be impeached. This process typically involves gathering evidence, holding hearings, and examining the official's conduct to determine if there are grounds for impeachment, such as committing "high crimes and misdemeanors." If the inquiry finds sufficient evidence, it may lead to articles of impeachment being drafted. These articles are then voted on by the legislative body, and if approved, the official may face a trial to decide whether they should be removed from office.
