President Donald Trump approved a California disaster declaration, ordering federal aid to help battle the wildfires sweeping through Northern California, the White House said Tuesday.

The declaration comes as state officials announced 15 people have died as a result of the 17 fires burning more than 110,000 acres across the region. More than 2,000 homes and buildings were destroyed,

Trump says he spoke Monday night with California Gov. Jerry Brown to "let him know that the federal government will stand with the people of California. And we will be there for you in this time of terrible tragedy and need."

Federal aid will be sent to help supplement state and local recovery efforts for the areas affected in the fires that began Sunday evening, the White House said. There is also funding available for for emergency work in BUtte, Lake, Mendocino, Napa, Nevada, Sonoma and Yuba counties.

Trump says he is also continuing to pray for those grieving and wounded in the Las Vegas mass shooting and is also thinking of the people affected by hurricanes Harvey, Irma and Maria.

He says, "We have to never forget."
