Answer:
First Amendment.
Step-by-step explanation:
Adopted on 15 December 1791, First Amendment of the U.S. Constitution is one of the ten amendments that compose the Bills of Rights. This Amendment precludes the state from making regulations which respect an institution of religion, prevent the free exercise of religion, or decrease the freedom of speech, the freedom of the press, the right to peaceably gather, or the right to appeal the government for a redress of objections. Moreover, the U.S. Supreme Court held that the First Amendment preserves the right to attend a nonviolent public gathering.
