NORRISTOWN — Pennsylvania’s top prosecutor received sensitive e-mails from aides about news coverage of her office on personal accounts, preventing investigators from seeing many of her responses, according to a document obtained Wednesday by The Associated Press.

Attorney General Kathleen Kane was charged this month with obstruction and conspiracy for allegedly leaking grand jury material to the Philadelphia Daily News and then lying about it.

An affidavit seeking a search warrant in April shows that Kane had received some e-mails from top aides on her private AOL and Yahoo accounts. They included proposed responses to questions from a Philadelphia Inquirer reporter who worked on an article critical of Kane, as well as links to the Daily News article the day it appeared in June 2014.

Kane, who has maintained her innocence, told a grand jury investigating the leak in November that she didn’t read the article until August 2014.

“The attorney general receives a large volume of e-mails on a daily basis and has to prioritize the ones most immediately pressing. It is highly probable that she never got to go back and read the e-mail in question,” Chuck Ardo, Kane’s spokesman, said Wednesday.

He said that he would check to see whether the attorney general’s office has a policy about the use of private e-mail accounts to conduct business.

Investigators served the search warrants, and one of the e-mails in question was cited at Kane’s preliminary hearing on Monday.

Investigators said Kane’s use of personal e-mail accounts and the limited scope of e-mails provided by the grand jury prevented them from seeing many of her responses.

Prosecutors say Kane leaked the information to smear two prosecutors who she believed had provided information for a March 2014 story in The Philadelphia Inquirer that revealed her decision not to pursue charges in a separate corruption case.

In one exchange included in the search warrant, Kane’s then-spokesman attached a copy of the Daily News article and said, “need some help on this.” It’s unclear if Kane responded. The spokesman eventually instructed a colleague on how to respond to a reporter asking about the article: “No comment. That’s it. No background, no explaining, no comment.”

Also Wednesday, court officials released more than a thousand pages of records in response to Kane’s request, including scores of e-mails that contained sexually explicit images and insensitive jokes.

She contends those e-mails show that two former state prosecutors “corruptly manufactured” the criminal charges against her because she was threatening to reveal their use of office computers to send or receive pornography.
