It was a big deal at the time. While Bill Clinton was not being investigated it was a sudden firing. There was heartburn over it.  
The excuse had a flimsy side mostly being too independent and not tracking inter department detail along with frivolous spending habits. Clinton's best buddy Vincent Foster turned up dead the next day if I remember right. The right wing plays a rough game. Do a little research it won't hurt. There is subtle rewrite history enshrined in some political articles that refer back to the time. You may have to pull up the actual articles of the day.
