Pennsylvania's top prosecutor is taking on the new role of criminal defendant.

State Attorney General Kathleen Kane is to be arraigned Saturday in the Philadelphia suburb of Montgomery County on charges that she leaked secret grand jury information and then lied about it.

The 49-year-old Kane is the first woman and first Democrat to be elected Pennsylvania's attorney general. She maintains she is innocent amid growing calls for her resignation from editorialists and fellow Democrats, including Gov. Tom Wolf.

Prosecutors say Kane leaked grand jury information to a newspaper to get even with a former state prosecutor she thought made her look bad. They also say she enlisted aides to spy on office employees and others to keep tabs on a grand jury probe into the leak.
