What Is Impeachment and How Does It Work
Impeachment is a constitutional process where the House of Representatives brings charges against a federal official, and the Senate conducts a trial. The House votes on articles of impeachment, and a simple majority is required to impeach. The Senate then holds a trial, and a two-thirds supermajority is required to convict and remove the official from office. The process is outlined in Article I, Sections 2 and 3 of the U.S. Constitution, which grants the House the sole power of impeachment and the Senate the sole power to try impeachments. For a detailed breakdown of the constitutional text, see the official U.S. Senate overview here.
Federal judges, the President, Vice President, and all civil officers of the United States are subject to impeachment. The grounds for impeachment are treason, bribery, or other high crimes and misdemeanors. The process typically begins with an impeachment inquiry, often led by a congressional committee, followed by a vote in the full House. If articles pass, the House appoints managers who act as prosecutors in the Senate trial. The Chief Justice of the United States presides over presidential impeachment trials. The outcome is either acquittal, removal from office, or removal and a potential disqualification from holding future federal office.
How Impeachment Has Been Applied in U.S. History
As of the latest public data, the House has impeached a total of 21 federal officials, including three U.S. Presidents. The Senate has convicted and removed eight federal judges. The three presidential impeachment cases are Donald Trump (twice, in 2019 and 2021), Bill Clinton (1998), and Andrew Johnson (1868). Richard Nixon resigned in 1974 after the House Judiciary Committee approved articles of impeachment, but the full House never voted. The most recent impeachment of a president was the second impeachment of Donald Trump on January 13, 2021, for incitement of insurrection, with the Senate trial concluding on February 13, 2021, with an acquittal. For a timeline of major impeachment events, the Congressional Research Service provides a detailed report here.
The impeachment of federal judges has often focused on ethical violations, corruption, or mental incapacity. The Senate has removed judges for offenses such as tax fraud, bribery, and making false statements. In the corporate and financial context, while private companies do not face impeachment, executives can be removed by board votes and face regulatory actions from agencies like the Securities and Exchange Commission. The SEC can bring civil enforcement actions, delist companies, and impose fines. For example, the SEC regularly publishes enforcement actions and litigation releases on its website, which detail cases involving fraud, insider trading, and market manipulation here.
Impeachment vs. Removal in Corporate and Regulatory Contexts
In corporate governance, removal of a CEO or board member follows internal procedures, not the constitutional impeachment process. Public companies typically have bylaws and shareholder agreements that define removal mechanisms. For instance, Tesla's board can remove a director with or without cause, subject to state law and the company's charter. Major institutional investors, such as BlackRock and Vanguard, often vote on board seats at annual meetings, and proxy statements detail removal procedures. The SEC requires public companies to disclose director qualifications and removal processes in their definitive proxy statements here.
Financial regulation agencies can also effectively remove executives through enforcement actions,
