Well, the rule for everyone says that you don't have to disclose your college or grad school transciprts to the public if you don't want to. Hence I don't see how you can argue Obama is getting special treatment here.
Now that just depends does it not on exactly what position everyone is applying for employment? But I will agree that there is a 'right' we all at least for the time being do share, taking the 'fifth'.
You know little about rules. Oh, of course, unless you meant there are different rules for those whom we have elevated to Royalty.
