The American and Ukrainian governments, it turns out, are legally required by treaty to render mutual legal assistance in criminal matters.
The treaty, signed at Kiev on July 22, 1998, provides in Article 1 that “[t]he Contracting States shall provide mutual assistance, in accordance with the provisions of this Treaty, in connection with the investigation, prosecution, and prevention of offenses, and in proceedings related to criminal matters.” As every schoolchild used to know before teachers’ unions, New Age thinking, and identity politics dumbed down the educational system, under the Supremacy Clause of the U.S. Constitution, properly ratified treaties are the supreme law of the land.
The document states that each “Contracting State shall have a Central Authority to make and receive requests pursuant to this Treaty.” For the U.S., it is “the Attorney General or a person designated by the Attorney General.” For Ukraine, it is “the Ministry of Justice and the Office of the Prosecutor General.”
