On 7 January 1999, the United States Senate commenced the impeachment trial of President Bill Clinton, following the House of Representatives' decision to impeach him on charges of perjury and obstruction of justice related to his extramarital affair with White House intern Monica Lewinsky.
This pivotal moment marked only the second impeachment trial of a sitting US president, setting the stage for a deeply polarised political and public debate over the limits of presidential conduct and accountability.
