As a result of Donald Trump's presidency, impeachment was again thrust into the spotlight of American political discussion. However, its history goes back to the very founding of the nation, when American colonists, remembering their grievances against their former king, entrenched the process in their new Constitution. The Law of Presidential Impeachment breaks down the law and politics of this process, providing a comprehensive, nonpartisan, and up-to-date explanation of the Constitution's various mechanisms for holding presidents accountable for their misdeeds. Based on a lifetime of scholarly research, as well as unique experience as a witness and consultant in the impeachment trials of Bill Clinton and Donald Trump, Michael J. Gerhardt's book takes the reader back to the basics of presidential impeachments. Rather than provide reasons for or against impeachment particular presidents, Gerhardt explains the law and procedures that govern impeachment, examining a number of significant, yet under-explored, issues and themes.
