Biden says he prays incoming Trump administration keeps focus on LA fire response

President Joe Biden said on Friday he prays the Trump administration continues the focus on the federal response to the deadly wildfires that have ravaged Southern California.

Biden said he expected the death toll to rise as he was briefed by federal and state officials in the Oval Office. At least 10 people have been killed, and more injured, as fires continue to burn through the Los Angeles area.

With just days left in office, Biden said they've been coordinating with the incoming administration on the federal actions being taken to assist in fire management and help victims recover.

"My hope is that they'll have -- at least acknowledge we have some significant experience in this, we've done really well on it. I'm praying that they continue the focus," the president said.

David Muir anchors a special edition of "20/20" with continuing coverage of the deadly California fires. “American Catastrophe: LA Burning - A Special Edition of 20/20” starts tonight at 9/8c on ABC.

More than 30,000 acres have been burned this past week as five fires sprawled from the Pacific Palisades to Pasadena. Roughly 150,000 people were under evacuation orders and thousands of structures have been destroyed, including local landmarks.

FEMA Administrator Deanne Criswell, who is on the ground in Los Angeles, said the tragedy is one of the worst disasters she's witnessed in her four years leading the agency and that the rebuild will be complex.

"This recovery journey is going to be long, but we are going to be there with them to support them every step of the way," Criswell said as she virtually joined the White House press briefing.

Criswell said FEMA had enough money to immediately respond to the fires, highlighting the $27 billion provided for the agency's disaster fund by Congress in December.

Pressed by ABC News Chief White House Correspondent Mary Bruce on what the cost may be compared to other natural disasters, Criswell said it was hard to put an exact number as they continue to survey damage but that they "know that this is going to be billions."

Criswell, discussing the transition, said FEMA has a dedicated staff that will continue to support Californians and a "whole team" dedicated to working with President-elect Donald Trump's transition operation.

"They're providing regular briefings to them on a daily basis and so we're providing whatever information that they ask for," she said.

Trump has pointed blame at Democrats, including Biden and Newsom, and spread some misinformation as the fires unfold. Criswell was asked if any such misinformation came up during their briefings with his team, though she did not directly respond.

President Biden on Thursday announced the federal government would cover 100% of the recovery costs for Los Angeles for 180 days. That would include debris removal, which the administration expects to be incredibly costly, as well as temporary shelters and pay for first responders.

"I mean, they look like a bomb hit," Biden said on Friday on the devastation. "They look like they're actually been blown up, entire sections of the cities blown up."

Biden noted that FEMA has activated their critical needs assistance, which provides a one-time payment of $750 to survivors so they quickly purchase critical items like water, formula, gasoline and prescription drugs.

Biden also again emphasized the need for Congress to act, noting he was not sure he would still be in the White House to do so.

"We're going to need the United States Congress to follow up with appropriations to help provide for significant help for fellow Americans who need this help to pay for these programs that we have, because a lot more is going to be happening," Biden said.

The issue of FEMA funding will likely come up when the next government spending deadline approaches in mid-March.
