An impeachment inquiry is a formal process used by a legislative body, such as the U.S. Congress, to investigate whether a government official, typically the President, has committed actions that warrant impeachment. This process often involves gathering evidence, holding hearings, and questioning witnesses to determine if there are grounds for impeachment. 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. If approved, the official may face a trial, which could result in removal from office if convicted.
