Each State has an Insurance Department. They are the supposed "hands-on" experts on the insurance marketplace in the State.
That said, insurance also has many political aspects, and there are a variety of interest groups (including consumers, insurers, agents and others) who have vested interests in the market.
All State laws, including those involving insurance, are enacted by State legislatures. The process pertaining to insurance laws is much like that involving the enactment of other laws. Insurance, however, is quite complicated.
Insurance Departments are involved in the promulgation of Rules that govern their own operation. They also establish precedents as to the interpretation of the statutes enacted by the State legislature.
The legislative branch is responsible for enacting laws.

A president is an executive officer. He is responsible for enacting and enforcing laws, however he does not write bills. That is a legislative function.
The second amendment prohibits states from enacting laws banning guns. However, all states and the federal government have laws limiting possession of certain weapons. For example, convicted felons are not allowed to own firearms anywhere in the US.
