The Pinchot–Ballinger controversy, also known as the "Ballinger Affair", was a dispute between U.S. Forest Service Chief Gifford Pinchot and U.S. Secretary of the Interior Richard A. Ballinger that contributed to the split of the Republican Party before the 1912 presidential election and helped to define the U.S. conservation movement in the early 20th century.
