California Gov. Gavin Newsom expressed frustration over Pacific Gas and Electric (PG&E) at a news conference today in Sonoma County, saying the utility company "simply did not do their job."

“We will hold them accountable,” Newsom said, referring to PG&E. “This is not the new normal, this cannot continue."

Newsom was in Sonoma County today visiting communities affected by the Kincade Fire, which has burned at least 21,900 acres and destroyed 49 structures.

Bill Johnson, the utility's CEO, said it's too soon to tell what caused the fire or where it started. An investigation is underway.

Some background: In recent years, PG&E has been under fire for the role its equipment played in a series of catastrophic blazes across the state, including last year's deadly Camp Fire.
