NORRISTOWN — Pennsylvania Attorney General Kathleen Kane’s driver was convicted Tuesday of contempt of court after a judge found he snooped through office mails to keep tabs on a secret grand jury investigating his boss.

Patrick Reese faces up to six months in jail, but his lawyer vowed to appeal the misdemeanor verdict.

Reese is a former small-town police chief near Scranton, Kane’s hometown, who has emerged as a close confidante during her troubled tenure. He makes just under $100,000 to head her security detail.

The e-mail snooping occurred while the attorney general last year was being investigated for allegedly leaking evidence from a 2009 grand jury case to the press. Prosecutors ultimately charged her with obstruction, perjury and other charges.

Kane has said she is being targeted as she tries to address a corrupt, good-old boy network in Pennsylvania politics.
