Last month, Bud Cummins, the U.S. attorney (federal prosecutor) for the Eastern District of Arkansas, received a call on his cellphone while hiking in the woods with his son. He was informed that he had just been replaced by J. Timothy Griffin, a Republican political operative who has spent the last few years working as an opposition researcher for Karl Rove. Mr. Cummins's case isn't unique. Since the middle of last month, the Bush administration has pushed out at least four U.S. attorneys, and possibly as many as seven, without explanation. The list includes Carol Lam, the U.S. attorney for San Diego, who successfully prosecuted Duke Cunningham, a Republican congressman, on major corruption charges. The top F.B.I. official in San Diego told The San Diego Union-Tribune that Ms. Lam's dismissal would undermine multiple continuing investigations. In Senate testimony yesterday, Attorney General Alberto Gonzales refused to say how many other attorneys have been asked to resign, calling it a personnel matter." Such a wholesale firing of prosecutors midway through an administration isn't normal. U.S. attorneys, The Wall Street Journal recently pointed out, "typically are appointed at the beginning of a new president's term, and serve throughout that term." Why, then, are prosecutors that the Bush administration itself appointed suddenly being pushed out? For the first time the administration is really worried about where corruption investigations might lead. The purge of U.S. attorneys looks like a pre-emptive strike against the gathering forces of justice.
