Biden authorized DHS and FEMA “to coordinate all disaster relief efforts.”
The three people were found Thursday night and have not yet been identified, the mayor said.
As of Friday morning, 99 people are still unaccounted for.
A White House statement released at around 1 a.m. ET confirmed the president authorized the Department of Homeland Security (DHS) and the Federal Emergency Management Agency (FEMA) “to coordinate all disaster relief efforts which have the purpose of alleviating the hardship and suffering caused by the emergency on the local population, and to provide appropriate assistance for required emergency measures…”
FEMA was authorized to identify, mobilize and provide equipment and resources to alleviate the impacts of the emergency, the statement read. That includes “debris removal and emergency protective measures, including direct federal assistance.”
Authorities are still trying to understand the cause of the collapse, and rescue efforts remain in effect. Cava said there is no evidence of foul play.
