standard operating procedure for his administration? is there anything unusual about the fact that there was no announcement or the fact that there was no announcement to replace these attorneys? >> the first point is absolutely a prident can remove u.s. attorneys at will, they serve at the pleasure of the president and it is not unusual for a new president, especially when there's been a change of party, to replace the 93 top federal prosecutors in federal districts around the country. typically it happens on a more rolling basis with transition time and we'll replace this guy and then that guy and then this woman or as you mentioned earlier there was one precedent for a mass firing which came from president bill clinton in march of -- 1993 even that was a little different than this then however because the people weren't all told the pack up their offices and get out by the close of business that day.
