26. Congressional privileges are not absolute.

Under the Constitution, members of both houses enjoy the privilege of being free from arrest in all cases, except for treason, felony, and breach of the peace. This immunity applies to members during sessions and when traveling to and from sessions. The term "arrest" has been interpreted broadly, and includes any detention or delay in the course of law enforcement, including court summons and subpoenas. The rules of the House strictly guard this privilege; a member may not waive the privilege on his or her own, but must seek the permission of the whole house to do so. Senate rules, on the other hand, are less strict, and permit individual senators to waive the privilege as they see fit.

The Constitution also guarantees absolute freedom of debate in both houses, providing, "for any Speech or Debate in either House, they shall not be questioned in any other Place." Hence, a member of Congress may not be sued for slander because of remarks made in either house. However, each house has its own rules restricting offensive speeches, and may punish members who transgress them.
