The First Amendment to the Constitution says: Congress should make no law regarding a foundation of religion, or disallowing the free exercise thereof, or shortening the right to speak freely, or of the press; or the privilege of the general population serenely to amass, and to request of the Government for a review of grievances.
The First Amendment secures a few fundamental opportunities in the United States including flexibility of religion, the right to speak freely, the flexibility of the press, the privilege to gather, and the privilege to appeal to the administration. It was a piece of the Bill of Rights that was included in the Constitution December 15, 1791.
