HARRISBURG, Pa. (WPVI) -- Sources tell Action News that Pennsylvania Attorney General Kathleen Kane will be charged Thursday after an ongoing investigation into a grand jury leak. The exact charges are not yet known. The investigation centered on whether Kane had a role in disclosing information about a 2009 grand jury investigation to the Philadelphia Daily News last year. A grand jury recommended in December that Kane be charged for engaging in a cover-up and lying about her role in the leak. The grand jury's allegations were referred to Montomgery County District Attorney Risa Vetri Ferman.
