Is it appropriate to have a recommender who you did not note in your cover letter as sending a LOR, send an additional LOR to the chambers? I already met the required number of LORs (and they were sent a while ago), but this additional recommender is a former judge and wants to write a LOR. I am wondering if it will be beneficial or just confusing to receive a LOR seemingly out-of-the-blue?

I added an additional LR (a 5th one at that) onto OSCAR even though my Oscar and paper cover letter didn't include the name. No one asked about it and I got the clerkship.
