I need to find the terms for these questions. I have been unable to find any of these terms.

Question

-What is the term for the legal protection members of Congress have?
-What is the name for the private meetings in which Republican and Democratic members in each house choose their own leaders?
-What is the term for ending debate or speeches in the Senate?

Thanks
