Summary
The author concludes that the mayor acted improperly. She builds her argument on two premises:
(1) If a public official uses their position to benefit themselves, it is improper.
(2) The mayor used her position to benefit a relative. 
Notable Assumptions
The author attempts to trigger the conditional in premise (1) using premise (2), but the author is assuming that using one’s office to benefit a relative also benefits oneself. We need a rule linking these two ideas, which gives us the following prediction:
If one uses their office to benefit a relative, this benefits oneself.
