The impetus for Gutzon Borglum's trips to Washington D.C. in the 1930s was his ambitious project to create Mount Rushmore, a monumental sculpture of four U.S. presidents. He sought funding and support from the federal government, as well as public interest in the project, which aimed to celebrate American history and democracy. Borglum's vision required collaboration with politicians and the National Park Service to secure the necessary resources and permissions for the colossal undertaking.
