THE FIRST AMENDMENT TO THE CONSTITUTION

"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and 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.
