When President Clinton fired all (93?) U.S. attorneys, it was a non-story. But when President Bush fires a handful, it is somehow a scandal.
The U.S. attorneys serve at the pleasure of the President. What the House panel hopes to find with its silly subpoenas of Bush aides falls into one category: More scandal. And if they don't find any there, the Democrats will continue to throw excrement on the walls to find out what sticks.
I fart in their general direction.
