Two of the most prominent U.S. insurance companies have responded to President Joe Biden’s call to cover additional living expenses for policyholders in Louisiana who evacuated their homes ahead of Hurricane Ida, but were not under specific mandatory evacuation orders.

Allstate and USAA have agreed to cover additional living expenses for policyholders in the state who evacuated their homes, a White House official told CNBC.

More companies were expected to follow suit, said the official, who requested anonymity in order to discuss efforts still underway.

Typically, insurance policies only cover additional living expenses for policyholders who have been ordered to evacuate their homes ahead of major storms, not for those who choose to leave their homes voluntarily.
