Pennsylvania Attorney General Kathleen Kane is expected to face criminal charges as soon as Thursday in a media leak case, local media reported on Wednesday.

A special grand jury in January recommended charges of perjury and obstruction against Kane in connection with an allegedly illegal leak to a Philadelphia newspaper.

Kane is expected to surrender to Montgomery County detectives, and her arraignment will be handled by a local district attorney, WPVI TV, the local ABC affiliate, said citing sources.

Since April, Montgomery County District Attorney Risa Vetri Ferman has been investigating the grand jury's conclusion that Kane leaked secret investigative information to the Philadelphia Daily News to embarrass a political rival, the Pittsburgh Tribune-Review reported.

The exact charges were not known, local media said.

Kane, who in 2012 became the first Democrat and first woman to be elected Pennsylvania attorney general, has denied she broke any laws.
