"The current GOP presidential candidates really need to go back to school and study American history. In 1797 the United States government signed the Treaty of Tripoli. It was submitted to the Senate by President John Adams, receiving unanimous ratification from the U.S. Senate on June 7, 1797. It was signed by President Adams on June 10, 1797, and became the law of the land."
