This legislation authorizes the Secretary of the Interior to provide grants totaling up to $50,000,000 for the establishment of the Theodore Roosevelt Presidential Library in Medora, North Dakota. These funds are intended to preserve and make available materials relating to President Theodore Roosevelt's life and to offer interpretive and educational services. A crucial condition for receiving these federal grants is that the Theodore Roosevelt Presidential Library Foundation must first certify it has secured at least $100,000,000 from the State of North Dakota or other non-Federal sources. Importantly, these federal grant funds are explicitly prohibited from being used for the ongoing maintenance or operation of the Library. Beyond financial contributions, the bill also permits the Secretary to enter into agreements with the Foundation for the loan of federal artifacts and objects related to Theodore Roosevelt. These artifacts, which may include items from agencies like the National Park Service and the United States Fish and Wildlife Service, are to be provided without monetary consideration, particularly those not currently on public display. The Secretary will establish terms and conditions necessary for the preservation and exhibition of these loaned items. Furthermore, the legislation clarifies that the Secretary or any other federal entity will have no involvement in the day-to-day operation of the Library, unless specifically requested by the non-federal operating entity.
