They thought Clinton had been impeached more for political reasons than for wrongdoing.
The impeachment of Bill Clinton, the 42nd President of the United States, was kicked off in December 1998 by the House of Representatives and led to a trial in the Senate on two charges. On the one hand, one of perjury and on the other hand, one of obstruction of justice. These charges arised from a sexual harassment lawsuit filed against Clinton by Paula Jones.
