While it raised eyebrows, Booker’s suggestion that he would be willing to be expelled from the Senate for his release of committee confidential documents isn’t rare.
According to the U.S Senate, since 1789 the body has expelled 15 members. Of that 15, 14 were charged with supporting the Confederacy during the Civil War — a vastly different charge than what Booker faces.
In other cases, the Senate merely considered expulsion proceedings but either found the given member not guilty or failed to act before that member left office. In those cases, the Senate notes, corruption was the main cause for the expulsion complaint.
The Senate could, however, move to impose a less severe form of punishment known as “censure.” A censure doesn’t remove a senator from office but the official statement of admonishment or disapproval can have equal lasting damage to an outright expulsion. The Senate has censured only nine members.
