The Constitution was written in the summer of 1787 in Philadelphia, Pennsylvania, by delegates from 12 states, in order to replace the Articles of Confederation with a new form of government. It created a federal system with a national government composed of 3 separated powers, and included both reserved and concurrent powers of states.

The constitutional principles of the American Founding that guided American politics before the Civil War were increasingly altered as a new approach to governance become predominant in the early twentieth century. The rise of an administrative state centralized more power in the hands of federal agencies in the executive branch and blurred the relationship of the branches of government and their respective constitutional powers. Even though the Constitution specifically granted authority to Congress to regulate interstate commerce in its enumerated powers in Article I, Section 8, Congress increasingly delegated that authority to the executive branch.

When Andrew Johnson became President upon Lincoln’s assassination, he hoped to restore the Union according to a plan that would be lenient toward the South. Lacking congressional support and political skills, Johnson found himself in a show-down with Republicans in Congress who wanted to remake the South in the image of the North, raise up blacks and poor whites, and guarantee full civil and political rights for the freedmen. This clash of goals and strategies led to the first presidential impeachment trial in our history—a test of the constitutional principles of separation of powers and checks and balances. In the end, the Founders’ mechanism of three co-equal branches of government proved strong enough to resolve the crisis.

Use this Lesson alongside The Impeachment of Andrew Johnson Decision Point to introduce students to the concept of impeachment and how it has been used throughout U.S. history.

In the highly charged partisan politics of the 1990s, President Bill Clinton’s personal indiscretions led to the second impeachment trial in our history. Independent Counsel Kenneth Starr was investigating Clinton’s pre-presidential financial dealings. In a separate case, Clinton was being sued by Paula Jones for sexual harassment. Jones called a young White House intern named Monica Lewinsky who had been having an relationship with the President to give testimony. Clinton denied the Lewinsky affair under oath in his deposition in the Jones case. This denial caught Starr’s attention, who suspected the President had committed perjury and obstructed justice. Starr assembled a grand jury and issued dozen of subpoenas, and eventually offered Lewinsky immunity in return for her testimony. When Clinton testified for Starr’s grand jury, he gave evasive answers. He ultimately admitted the Lewinsky affair to the American people that night. The House of Representatives impeached Clinton in 1998 on strict party lines, but in the Senate trial, Republicans fell far short of the two-thirds majority needed to convict.

This lesson allows students to analyze the Constitution and ask questions about how the Constitution allows for impeachment of the President.
