California's top insurance regulator is launching a probe into State Farm over its handling of claims from Los Angeles-area wildfires that broke out in January.

California’s top insurance regulator on Thursday launched an investigation into State Farm over the company’s handling of claims from the January Los Angeles-area wildfires.

The investigation comes after survivors of the Palisades and Eaton fires said that the state’s largest home insurer was delaying and mishandling claims regarding damage to their homes and possible contamination from smoke.

The blazes destroyed thousands of buildings around Los Angeles, killed 30 people and displaced thousands of others. They were estimated to be among the costliest natural disasters in U.S. history.
