State-level solicitors general perform a similar role in overseeing state government litigation before their respective state supreme courts.

Example: The U.S. Solicitor General is responsible for representing the federal government in cases before the Supreme Court. For example, if a state challenges a federal law, the Solicitor General would argue on behalf of the federal government to defend the law.

The Solicitor General's role is to ensure that the federal government's position is effectively presented and that the law is upheld.
