So, if all US Passports are issued on behalf of the Secretary of State, the person sitting in that Cabinet position could therefore issue a passport to him/herself. As of today, that would mean Hillary issues her own US Passport.

Say if Bill and Hillary went to a personal skiing trip up to Whistler, I'm sure Bill uses his own passport, but what about Hillary?

And if Hillary is say, visiting Japan to hold meetings with her Japanese counterpart for US-Japan related diplomatic talks, how does she enter Japan?
