Answer:
A governor declares a new state religion.
Step-by-step explanation:
The First Amendment to the Constitution establishes, among other rights, the right of the inhabitants of America to exercise freedom of worship, by means of which Congress may not establish an official religion or prohibit the exercise of any. Through these precepts, the inhabitants of the United States see their right to the free choice of their beliefs and to the free celebration of them guaranteed, without any interference by the government.
In this sense, the fact that a governor imposes an official religion in his state would constitute a clear violation of this Amendment.
