Two years ago, Philadelphia District Attorney Seth Williams told a group of reporters that his arch-rival, former Pennsylvania Attorney General Kathleen Kane, was “her own worst enemy.”

But after his indictment late last month on federal bribery charges, preceded by his payment of a record fine stemming from his failure to report $160,000 in gifts on his financial disclosures, it appears that the shoe is now on the other foot.

Williams' statement about Kane came during a press conference in which he announced he'd filed charges in a shuttered corruption sting involving six black Philadelphia Democrats—cases that Kane had dismissed as racially motivated and unprosecutable. Amid the public feud between the two prosecutors, Williams was able to secure guilty pleas from multiple defendants.
