The impeachment process for the President of the United States is as follows:

1. Investigation: The House Judiciary Committee investigates whether there are grounds to impeach the President.
2. Articles of Impeachment: If the Judiciary Committee believes there are grounds for impeachment, it drafts articles of impeachment, which are then voted on by the House of Representatives.
3. Impeachment: If a simple majority of the House votes in favor of impeachment, the President is impeached. This means that the President has been formally charged with wrongdoing.
4. Trial: The Senate then conducts a trial to determine whether the President is guilty of the charges laid out in the articles of impeachment. The Chief Justice of the Supreme Court presides over the trial, and Senators act as the jury.
5. Conviction or Acquittal: If two-thirds of the Senate votes to convict the President, the President is removed from office. If the Senate does not reach a two-thirds majority, the President is acquitted and remains in office.

It is worth noting that the impeachment process is a political process rather than a criminal one, and that the grounds for impeachment are defined broadly in the US Constitution as “high crimes and misdemeanors.”
