House Homeland Security Chairman Peter King (R-N.Y.) said Saturday there is a possibility that federal aid for victims of Hurricane Sandy may not pass by year’s end.

Citing strong opposition among colleagues to a supplemental spending bill, King warned that Congress may not approve Sandy relief funds if it fails to act this week.

“Doing all I can, but if Congress doesn’t approve Sandy aid for NY before Christmas, I don’t think it’ll get done. Too many oppose it in DC,” he said in a statement posted on Twitter Saturday.

King is stepping down as the Homeland Security panel’s chairman and will be replaced by Texas Rep. Michael McCaul (R).
