Just woke up, made coffee and read Your reply. Interesting about Pelosi. Did some research and found this. Yes. Article I, Section 6 of the Constitution provides, in part: “They shall in all Cases, except Treason, Felony and Breach of the Peace, be privileged from Arrest during their Attendance at the Session of their respective Houses, and in going to and returning from the same; and for any Speech or Debate in either House, they shall not be questioned in any other Place.” The first sentence quoted above gives Representatives and Senators limited immunity from arrest for some offenses while Congress is in session. It does not grant them immunity from indictment and subsequent prosecution, however.
