What did roosevelt mean when he said that the president is the "steward of the people

Teddy Roosevelt stated that he was a "steward of the people" in the sense that he broadened presidential power in order to do more for all people.  He broke up monopolies and helped to create legislation to break up even more trusts.  He championed the Food and Drug Act.  He was responsible for getting the public behind the national park movement.  He gave impassioned speeches.  He lent his opinion to collegiate athletics and American foreign policy.  His domestic policy was known as the Square Deal.  He spoke out against anarchism when it was a growing and dangerous movement in this country.  For all of these reasons, Teddy Roosevelt was one of America's first modern presidents in that he made sure that the presidency was a vocal part of national government and a part of the lives of American citizens.
