In college I interned for course credit in Richard Gephardt’s office when he was House Majority Leader and the next semester for the DNC. Both were useless. Answered phones, sorted mail, wrote a few replies to constituent letters.
The only real value of the internship was getting to use the Congressional Research Service for school assignments. (I plagiarized a paper on NAFTA. My professor loved it.) I made a point of jerking off in a bathroom in the Rayburn House Office Building just so I could say, 20 years later, I jerked off in Congress.
This is like how when I interned for Conde Nast for free I made a point of stealing coffee table books and doing poppers in the elevator.
