Which of the following is NOT a source of insurance regulation?

The President of the United States is not a direct source of insurance regulation. Insurance regulation primarily occurs at the state level in the United States, where each state establishes its own laws and regulations governing insurance practices within its jurisdiction. This allows for a more localized and tailored approach to insurance regulation that reflects the specific needs and circumstances of each state's residents.

While federal government legislation can impact insurance, such as through laws that address specific areas like health insurance or the financial crisis (like the Affordable Care Act or the Dodd-Frank Act), it does not serve as the primary source of insurance regulation. Additionally, judicial rulings play a crucial role in interpreting and enforcing insurance laws, helping to clarify statutory provisions and resolve disputes. Therefore, the key distinction here is that, while federal legislation and judicial rulings influence insurance regulation, the President does not establish insurance regulations or policies directly pertaining to the insurance industry.
