So I have a nomination from one of my senators already on file with both the USNA and USAFA. However, I got a call today and I was told that I am the principal nominee for my other senator to the USNA. Do I need to call the first senator to decline the nomination? Do I need to call Navy and tell them that? Or should I just take both and wait it out? I don't want to risk anything. Also, what exactly does it mean that I am the principal nominee?
