Congress can impeach and remove its own members, which is pretty rare because a congressperson has to actually do something really contrary to law or the chamber rules to get kicked out. They can also be censured by their chamber (in which they lose all their committee chair positions but still keep their seat) or be formally reprimanded for bad behavior.
It’s really up to the constituents (the people represented) to kick their Congresspeople out if they’re not doing their job. It’s unfortunate that so many people focus on voting for high offices like the President because they forget that it’s Congress that is the major policy-maker of the country.
Ladyhistory, I love you and your blog, so I just want to jump in and point out that it’s actually kind of up-in-the-air whether members of Congress can be impeached. Only the House of Representatives has the power of impeachment. Once the House impeaches an official (President, Vice President, member of the Supreme Court, or “civil officers” of the United States), the Senate sits as a jury and, if the impeached officer is found guilty by a 2/3rd vote, he or she is removed from office.
The question is whether members of Congress are “civil officers” of the United States. Many people argue that they are not. The House has only impeached one member of Congress — Senator William Blount at the end of the 18th Century. When Blount’s case went to the Senate for a trial, the Senate decided that they didn’t have the jurisdiction to try a member of Congress. Instead, they expelled him. Expulsion is the way that the House and Senate have tossed out members who would otherwise be impeached, and the precedent set by the Blount case has led to Congress expelling members from time-to-time (like the Southern Senators who supported the Confederacy during the Civil War or members convicted of significant crimes). Expulsion is rare because once a member of Congress realizes that they are likely about to be expelled, they usually resign.
Thanks for the additions! I teach high school United States Government, so I guess I should have known more details lol. I knew about the normal impeachment of officials, but was always sort of iffy on congressional impeachment because of the House having soke constitutional rights to do that (and having to teach the difference between impeachment and senatorial conviction is still confusing to students!). I just wasn’t sure if impeachment was roped in with expulsion, since I remember the Constitution giving both chambers the power to make their own rules but not being too specific about enforcement…?
