Perhaps I could add some information that might be relevant here.
With regard to the budget and the staffing of my office, there are offices of national science advisors and chief scientists around the world. In the United Kingdom, Sir David King, in his office, had a staff of 120 people, and I haven't bothered to ask what his expenditures are, but I can tell you that it's multi-millions of dollars. Jack Marburger in the United States has a staff of 60 people and similar expenses.
The fact of the matter is that with an international mandate my office was hosting international visitors. In fact, you can't not provide coffee and donuts and the occasional meal for international visitors.
