VP Nomination Letters

As I am learning about the VP nomination process it looks as if he just throws it back to the various academies, "here pick one and go with it". Anyhow my question is that it states that three letters of recommendation are required similar to most other nominations but you are supposed to send the letters directly to the academy, ok pretty simple but who or to whom do you address it - "Dear Mr. Vice President" even though his web site states that he has nothing to do with it?

Thanks.
