Answer the questions at the end based on the text.

The United States Department of the Interior (DOI) is the United States federal executive department of the U.S. government responsible for the management and conservation of most federal land and natural resources, and the administration of programs relating to Native Americans, Alaska Natives, Native Hawaiians, territorial affairs, and insular areas of the United States. About 75% of federal public land is managed by the department, with most of the remainder managed by the United States Department of Agriculture's United States Forest Service. 

The Department is administered by the United States Secretary of the Interior, who is a member of the Cabinet of the President. The current Secretary is Ryan Zinke. The Inspector General position is currently vacant, with Mary Kendall serving as acting Inspector General. 

Despite its name, the Department of the Interior has a different role from that of the interior ministries of other nations, which are usually responsible for police matters and internal security. In the United States, national security and immigration functions are performed by the Department of Homeland Security primarily and the Department of Justice secondarily. 

The Department of the Interior has often been humorously called "The Department of Everything Else" because of its broad range of responsibilities.
