The Senators and Representatives shall receive a Compensation for their Services, to be ascertained by Law, and paid out of the Treasury of the United States. 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.
No Senator or Representative shall, during the Time for which he was elected, be appointed to any civil Office under the Authority of the United States, which shall have been created, or the Emoluments whereof shall have been encreased during such time; and no Person holding any Office under the United States, shall be a Member of either House during his Continuance in Office.
Members of Congress get paid from the US Treasury and are generally exempt from being detained for legal violations while Congress is in session. While serving they aren’t allowed to be hold any other offices. I’d never heard of the word emoluments before, so I took another trip to merriam-webster.com to look up emoluments:
the returns arising from office or employment usually in the form of compensation or perquisites
It’s a fancy word for salary. Good idea to not allow them to vote themselves raises for their current term.
