In unusually barbed criticism of a fellow prosecutor and fellow Democrat, Philadelphia's district attorney rebuked state Attorney General Kathleen Kane on Friday, saying she had needlessly killed a solid corruption investigation -- and besmirched the prosecutors who built the case.
In a statement to be published in the Philadelphia Inquirer on Sunday, Seth Williams faulted Ms. Kane for shutting down a "sting" operation that caught at least five Philadelphia Democrats, including four state representatives, on tape accepting money or gifts.
"She apparently has electronic recordings of numerous elected officials taking money while promising their votes -- and she has to let them off scot-free because she would be incapable convincing a jury of their guilt?" he wrote.
Ms. Kane has said she closed the investigation in part because prosecutors had made an unduly lenient deal with the case's undercover informant, dropping 2,088 charges against him in a massive fraud case in exchange for his cooperation. That, she said, rendered his credibility "horrendously tainted" and would have prevented prosecutors from winning in court.
Mr. Williams blasted that. "The Attorney General of Pennsylvania drops a case supported by hundreds of hours of devastating tapes because the main witness got a deal on a bunch of government fraud charges," he wrote. "As a DA, I think this might be the most disturbing aspect of the whole sordid spectacle. You don't have to be a prosecutor to know this is how it's done."
Adrian R. King Jr., Ms. Kane's first deputy attorney general, declined to respond to Mr. Williams' assertions.
Ms. Kane has said the sting investigation was poorly conceived, badly managed and possibly tainted by racist targeting of African-Americans. She also said the undercover operative, Tyron B. Ali, had been given "the deal of the century" by Frank G. Fina, the chief deputy attorney general who led the investigation.
Mr. Williams spoke out in defense of Mr. Fina and Claude Thomas, who served as the operation's lead agent. Both now work for Mr. Williams.
He said they had excellent records of prosecuting corruption, targeting Republicans and Democrats, blacks and whites in some of the most high-profile cases in recent state history.
As for Ms. Kane's suggestion that the sting investigation may have been tainted by racism, Mr. Williams wrote: "I am offended. I have seen racism. I know what it looks like. This isn't it."
Of Mr. Thomas, Mr. Williams said, "Like me, he is a black man. ... He has absolutely, unequivocally denied that he was asked to, or agreed to, engage in such reprehensible conduct. ... I believe he is telling the truth."
In a separate statement submitted to the Inquirer for publication Sunday, Mr. Fina mocked Ms. Kane for her decision to request to meet with the editorial board of the Inquirer on Thursday, only to arrive and decline to address the board or answer any questions. She did so upon the advice of her newly hired lawyer, Richard A. Sprague, who accompanied her to the meeting.
"I have not retained an attorney to advise me to speak, or to remain silent," Mr. Fina wrote. "I am an attorney."
Mr. Fina called for a televised public forum at which he and Ms. Kane could debate the merits of the investigation, which Mr. Fina said had been conducted "honestly, ably and with integrity."
Mr. Thomas also sent a statement to the Inquirer on Friday. In it, he vehemently rejected any suggestion that race played a role in the investigation.
"The assertion that I/we targeted African Americans is unequivocally and blatantly false," he wrote. "I did not target any persons by race, ethnicity or political affiliation."
As the Inquirer reported last week, Mr. Fina began the investigation in late 2010 in the final months in office of Attorney General Tom Corbett, a Republican who is now governor. When Ms. Kane became attorney general in 2013, she ended the investigation. No one was ever charged.
