Chооse the mаin pаttern оf orgаnization of the passage. Both our 17th president, Andrew Johnson, and our 42nd president, Bill Clinton, were raised by hard-working single mothers. Both were Southern Democrats. Both were impeached. Yet these superficial similarities in the careers of the two men mask dramatic differences between them. When Andrew Johnson fired Secretary of War Stanton, he was charged with violating the Tenure of Office Act, a law that probably was unconstitutional. His impeachment took place against the backdrop of a national debate over the course of post-Civil War Reconstruction, a debate that was intensely ideological. In contrast, Bill Clinton was charged with lying and obstructing justice, charges that stemmed from an extramarital affair the president had conducted with a young White House intern, Monica Lewinsky. Clinton’s impeachment reflected the bitter partisanship and personal animosity between Democrats and Republicans in the 1990s.
