SEE ALSO: DePasquale sworn in as state's auditor general

HARRISBURG - Amid loud applause and cheers, Kathleen Kane has been sworn in as the first woman and first Democrat to be elected as Pennsylvania's attorney general.

Gov. Tom Corbett, U.S. Sen. Bob Casey and state Chief Justice Ronald Castille were among the roughly 600 people gathered in the Capitol rotunda to witness Tuesday's ceremony.

In a speech, Kane vowed to protect Pennsylvanians against violent criminals, child molesters, scam artists and others. She said her office will be aggressive, efficient and focused.

Kane was among three Democrats who were sworn in to the state row offices Tuesday.

Eugene DePasquale, a former state representative from York, took the oath as auditor general and Rob McCord was sworn in to his second term as state treasurer.

They will serve four-year terms.
