What is impeachment in the U.S. government?
A constitutional process where the House charges a president or other federal official with 'high crimes and misdemeanors,' which can lead to a Senate trial.
How does impeachment proceed from start to finish?
The House investigates and votes to impeach by a simple majority. The Senate then holds a trial, with the Chief Justice presiding for presidential cases; a two-thirds vote is needed to convict and remove.
What does 'high crimes and misdemeanors' mean in practice?
It's a constitutional standard, not a precise crime. Congress uses it to describe serious misconduct or abuse of power on a case-by-case basis.
Have any presidents been removed from office through impeachment?
No. Presidents Andrew Johnson, Bill Clinton, and Donald Trump were impeached by the House but acquitted by the Senate; Richard Nixon resigned before impeachment. Impeachment of other officials has led to removals in some cases.
