The agency is being stretched as it works with states to assess damage from Hurricane Helene and delivers meals, water, generators and other critical supplies. The storm struck Florida last week, then plowed through several states in the Southeast, flooding towns and killing more than 160 people.

Mayorkas was not specific about how much additional money the agency may need, but his remarks on Air Force One underscored concerns voiced by President Joe Biden and some lawmakers earlier this week that Congress may need to pass a supplemental spending bill this fall to help states with recovery efforts.

"We are meeting the immediate needs with the money that we have. We are expecting another hurricane hitting," said Mayorkas, adding "FEMA does not have the funds to make it through the season."
