The First Amendment to the United States Constitution is the part of the United States Bill of Rights that expressly prohibits the United States Congress from making laws "respecting an establishment of religion" or that prohibit the free exercise of religion, infringe the freedom of speech, infringe the freedom of the press, limit the right to peaceably assemble, or limit the right to petition the government for a redress of grievances.
Although the First Amendment only explicitly applies to the Congress, the Supreme Court has interpreted it as applying to the executive and judicial branches. Additionally, in the 20th century, the Supreme Court held that the Due Process Clause of the Fourteenth Amendment applies the limitations of the First Amendment to each state, including any local government within a state.
I guess this means that the First Amendment applies to the State of Michigan too! Nice try.
