Who can be impeached?

"The President, Vice President and all Civil Officers of the United States, shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanors."

- Article II, Section 4 of the Constitution of the United States

As you can see from the excerpt above, any civil officer can be impeached. That means judges, senators, or even presidents can be impeached.

In all of U.S. history, only two presidents have been impeached. Andrew Johnson was impeached in 1868, and William (Bill) Clinton was impeached in 1998. Richard Nixon resigned in 1974 because he was about to be impeached.

Several judges as well as one senator and one cabinet member have also been impeached throughout U.S. history.

Who starts the impeachment process of a civil officer?

  • The answer is the House of Representatives.

The U.S. Constitution gives the House of Representatives the power to begin the impeachment process of a public officer. First, the House prepares articles of impeachment against the public officer. Then, the House votes to approve the articles of impeachment. If approved by a specific majority, the public officer will stand trial before the Senate.

The Senate acts as the court and jury over impeachment trials. The U.S. Constitution requires a two-thirds majority vote by the Senate to acquit (a vote of "not guilty") or convict (a vote of "guilty") a civil officer during an impeachment trial.

Both former Presidents Johnson and Clinton were acquitted by the Senate, so they were not removed from office. Just because a public officer has articles of impeachment brought against him or her, it does not mean they will necessarily be removed from office. It all depends on the Senate's vote.

Why do civil officers get impeached?

As you saw in the Constitution excerpt above, a civil officer can be impeached for:

  • treason
  • bribery
  • other high crimes and misdemeanors

Treason is defined in the Constitution as waging war against the United States or providing aid to its enemies. Bribery, while not defined, is commonly understood as the exchange of money or gifts to influence a public official.

Two of the House of Representatives impeachment proceedings were based on charges of bribery, and none were based on treason.

  • The remaining fell under high crimes and misdemeanors, but what does that even mean exactly?

At the Constitutional Convention in 1787, this phrase was understood to mean an official had abused the power of his office and was unfit to serve. Over the years, Congress has interpreted it different ways.

To better understand this charge, let's learn about the first U.S. president to face impeachment. Andrew Johnson, of the Democratic Party, became the 17th president after Abraham Lincoln was assassinated in 1865. Johnson was impeached in 1868 but fell one vote short of being convicted.

  • What were President Johnson's high crimes and misdemeanors?
