(CNN) - Several Democratic presidential hopefuls are calling for the impeachment of Supreme Court Justice Brett Kavanaugh after a new book provided unreported details of an incident of alleged sexual misconduct while he was a student at Yale.
Because justices receive lifetime appointments, removing one is harder than just calling up someone and firing them. In order to remove one, you have to impeach them.
The process is the same as impeaching the president of the United States. The House of Representatives would vote on whether to impeach the justice in question. If the justice is impeached, there would be a Senate trial.
The House needs only a simple majority to impeach a Supreme Court justice or any federal judge. To convict and then remove the justice or judge, the Senate requires a two-thirds majority.
In an interview with WNYC radio, House Judiciary Chairman Jerry Nadler said he had questions for FBI Director Christopher Wray regarding the agency's investigation of the allegations against Kavanaugh. Nadler has previously asked the National Archives to produce documents related to Kavanaugh's time in the George W. Bush White House.
The part of the Constitution that establishes the judicial system, Article III, leaves broad room for interpretation about how judges should behave in their roles.
"The Judges, both of the supreme and inferior courts, shall hold their offices during good behavior," the document states. The Constitution provides no further guidance about how judges should behave in office.
Impeachment and removal of federal judges is extremely rare. The House of Representatives has impeached only 15 federal judges since 1803, and eight of those impeachments were followed by convictions in the Senate, according to New York University's Brennan Center for Justice.
