Four months into the Obama Administration, loyal Bushie Mary Beth Buchanan is still clinging tenaciously to her post as U.S. attorney in Pittsburgh and is pursuing a politically flavored prosecution of former Allegheny County coroner Cyril Wecht. But after a federal appeals court ruled that the case had to be reassigned to an impartial judge, taking it away from George W. Bush-appointee Arthur J. Schwab, she’s having an extremely hard time. Yesterday, Judge Sean J. McLaughlin issued a 55-page ruling that all but eviscerated the case Buchanan has been attempting to bring. In the three year war of Buchanan versus Wecht, it’s increasingly looking like a decisive win for Wecht.
