Article I, Section 6“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.”
So, this seems pretty straightforward…being a Senator or Representative is a paid gig (yes, we know). And, they can’t be arrested while doing their jobs except in the case of “felony or treason”…so I guess spitting on the sidewalk or jaywalking gets a pass.
This second part is interesting…I guess (at least at the time of its writing) that a Congressman isn’t supposed to work another government job while they’re in office, and vice versa-a government employee isn’t supposed to be a congressman. So, in essence, no moonlighting…I guess.
