Over the past 200 years, Congress has conducted numerous high-level investigations that have riveted the nation, inspired landmark legislation, and transformed American history, including Watergate, Iran-Contra, 9/11, and Hurricane Katrina. Focusing on a wide array of subjects and issues, these investigations have covered some of the most significant events in our nation's past, including John Brown's raid on Harpers Ferry in 1859, the impeachment of Andrew Johnson in 1868, the Teapot Dome Scandal in 1924, the attack on Pearl Harbor in 1941, and the Army-McCarthy hearings in 1954. These events have been turning points in American history, and they are vital to our understanding of the U.S. government and political system.
