What groups did Roosevelt feel were a burden to the United
States?

In addition to revamping the Supreme Court, FDR believed that he needed to reform and strengthen the Presidency, and specifically the administrative units and bureaucracy charged with implementing the chief executive's policies. During his first term, FDR quickly found that the federal bureaucracy, specifically at the Treasury and State Departments, moved too slowly for his tastes. FDR often chose to bypass these established channels, creating emergency agencies in their stead.
