Answer:
In 1998, newspaper sources revealed that President Clinton had had a sentimental affair with Monica Lewinsky, a White House worker. Bill Clinton's impeachment was initiated by the House of Representatives on December 19, 1998 on two counts: perjury, as he had lied about not having had any kind of relationship with Lewinsky, and obstruction of justice, as he tried to prevent the truth from being ascertained regarding said affaire. Ultimately, Clinton was acquitted of these charges by the Senate on February 12, 1999, as the two-thirds of senators needed to convict the President were not obtained.
