Pennsylvania Attorney General Kathleen Kane is challenging one of her harshest critics to prosecute a public corruption case that she decided to abandon.
The Philadelphia Inquirer says Kane invited Philadelphia District Attorney Seth Williams, a fellow Democrat, to "bring whatever charges you believe to be appropriate.''
The newspaper has reported that four black Democratic state lawmakers from Philadelphia were captured on tape accepting cash from a confidential informant working for the state attorney general's office.
Kane squashed the investigation after taking office, saying it was poorly managed and might have improperly targeted people based on their race.
Williams has criticized Kane's decision. He says Kane's attacks will make it difficult for him to prosecute the case.
