This guide provides access to primary source materials that are being produced as part of the 2019 U.S. impeachment process, as well as information about the process itself. Primary source materials are being produced frequently while this process is taking place. Impeachment is "...the political process provided in the U.S. Constitution for investigating and potentially removing a specific class of officials from public office as punishment for political offenses."
