The Atlantic magazine reported on Tuesday that the US bought the biscuits near the end of Joe Biden’s Administration for around US$800,000 and that US taxpayers will spend another US$130,000 to destroy the food.
Senator Tim Kaine, a Democrat, said lawmakers had specifically raised the issue of the food with Rubio in March.
“Sometimes the tiniest detail really exposes the soul,” Kaine said.
“A government that is put on notice - here are resources that will save 27,000 starving kids, can you please distribute them or give them to someone who can?
“Who decides, no, we would rather keep the warehouse locked, let the food expire, and then burn it?”
Rigas said that the US remained the world’s largest donor, and he promised to learn further details about the biscuits.
“I do want to find out what happened here and get to the ground truth,” he said.
Rigas has also supervised hundreds of layoffs at the State Department as part of Trump’s sweeping cost-cutting drive first led by tycoon Elon Musk.
