From the Document: "I have concluded that it is not in the interest of the United States to become a party to the Arms Trade Treaty (Senate Treaty Doc. 114-14, transmitted December 9, 2016). I have, therefore, decided to withdraw the aforementioned treaty from the Senate and accordingly request that it be returned to me."
