The Federal Emergency Management Agency (FEMA) is working with families who lost their homes in the deadly Los Angeles wildfires, the agency's administrator said. FEMA Administrator Deanne Criswell told CNN on Thursday that the agency has yet to assess the damage, but more than 1,000 structures have been left destroyed or with damage from both the Pacific Palisades and Eaton fires. “We know that there’s going to be lots of families that are going to be in great need,” she said. On Tuesday, FEMA authorized the use of federal funds to assist California in combating the fires. The Fire Management Assistance Grant provides funds for up to 75 percent of eligible firefighting costs. FEMA’s Disaster Relief Fund allows for assistance in fighting fires. Eligible costs can include expenses for field camps, equipment use, materials, supplies and mobilization activities for fighting the fires, FEMA said in a release. In a post online Thursday, President-elect Trump criticized California Gov. Gavin Newsom (D) and Los Angeles Mayor Karen Bass over the fire response. He also slammed President Biden and argued FEMA has “no money.” Biden, meanwhile, has noted that “we’re doing anything and everything and as long as it takes to contain these fires,” while Newsom has hit back at Trump for his criticism amid the blazes and touted the president's support. With first responders still battling the flames and officials assessing the damage to the area, Criswell told CNN that what affects her most about wildfire victims is that families have lost everything. “They’ve lost all of their memories, all of their belongings, nothing for them to really even sift through,” Criswell said. “This makes the recovery process — both from a physical standpoint of having to rebuild but also the emotional standpoint — so difficult for so many people." Criswell said FEMA officials are in Sacramento and working alongside California’s emergency teams. FEMA’s teams will soon begin moving into shelters to help survivors register for assistance from the federal government, the outlet reported.
