. I'm sure having a LOR from a White House aide is not something that most Law Schools see, but since it is Yale, half of the class might be connected in some way or the other to who-is-who in
We strongly prefer letters from at least two faculty members who know your academic work directly. Professors who have worked with you on an individual basis—such as a senior thesis adviser or an honors adviser—are usually the best sources. Letters from employers are also acceptable, particularly for applicants who have been out of school for several years. Additional letters from college deans, chaplains, summer employers, and colleagues may be helpful, but we are most interested in letters from people who can realistically assess your academic potential.
if he's able to do the above, it would certainly be in your best interest to submit it. FWIW, i went the "two-faculty-members-and-an-employer-route," and that seemed to have worked in my favor. so, provided it isn't just filler, your additional letter should serve to only fortify your app.
