California fires live updates: At least 10 fire-related deaths, medical examiner says

Vice President Kamala Harris said her "heart goes out to all those being impacted by the devastating wildfires in Southern California."

In a Wednesday morning statement, Harris said she and her husband "are praying for our fellow Californians who have evacuated and we are thinking of the families whose homes, businesses and schools remain in harm's way."

"We are deeply grateful for the heroic first responders who are risking their own safety to fight the flames and help keep communities safe," Harris added.

The vice president said she had been briefed on the situation and was receiving "regular updates" on the fires. "I am also urging residents in the affected areas to listen to local officials, remain vigilant and evacuate immediately if told to do so," she added.

The White House is "committed to ensuring that no community has to respond to this disaster alone," Harris said, noting the mobilization of federal resources to suppress the fires and assist those affected.

"As a proud daughter of California, I know the damage that wildfires have on our neighbors and communities," Harris said.

"I also know that the impact is often felt long after the fire is contained. As we respond and as Californians recover, I will ensure that our administration is in constant contact with state and local officials."
