What actually happens with ‘unpaid’ Congressional interns is that they’re actually employed and paid by outside interest groups.
The lid blew off on that during Kavanaugh when one of Sheila Jackson Lee’s interns doxed Republican Senators.
Although I’m willing to bet that Ocasio-Cortez is actually oblivious to that when she made this announcement.
You should have put a (!) after oblivious and left it at that.
From your link, congresscritters have both interns and fellows assisting them:
Intern and fellow are not interchangeable because they arent even close to being the same thing. While internships are reserved for inexperienced college students, fellowships are usually serious policy positions and are typically filled by professionals working within other federal agencies or the private sector who are brought to a congressional office for a short stint to help a member of Congress better understand the agency or business for which that member has oversight responsibilities.
Apparently Freddie Mercury’s daughter (he DID do girls as well), learned the “fellowship” angle and will play to that.
