Pennsylvania Attorney General Kathleen Kane says she is innocent of any wrongdoing.

HARRISBURG — Portraying herself as a victim, Pennsylvania’s attorney general said Wednesday that criminal charges threatening to end her career were part of a “grand plan” to conceal pornographic and racially insensitive e-mails circulated among judges and state prosecutors.

“I am innocent of any wrongdoing,” Kathleen Kane said in her first public comments on the case. “I neither conspired with anyone nor did I ask or direct anyone to do anything improper or unlawful.”

She didn’t address the specific allegations leveled against her last week, saying she couldn’t on the advice of counsel. But she challenged a judge to make public the “filthy e-mail chain” that led to last year’s porn scandal, promising to call a second news conference and answer every question if the judge met her terms.

A suburban Philadelphia district attorney charged Kane with leaking grand jury information to a newspaper reporter in an attempt to embarrass a former prosecutor she believed made her look bad, and then lying about her actions under oath.

Kane, 49, faces up to seven years in prison on the most serious charge, perjury.

Reading a prepared statement, the attorney general described the leak investigation and criminal charges as a “stealth political weapon” to oust her from office and block her from challenging a judge’s order. She said the order bars the release of a collection of undisclosed pornographic, racially and religiously offensive e-mails sent on state computers.

She said the campaign to discredit her began immediately after her office uncovered pornographic and explicit videos, images and jokes in hundreds of e-mails while examining how state prosecutors under her predecessors handled the child sex abuse case against former Penn State assistant football coach Jerry Sandusky.
