“Jordan is facing a massive influx of refugees stemming from the humanitarian catastrophe in Syria,” Casey said. “I believe it is in the United States’ national security interest to help Jordan as they bear a significant burden in working to accommodate vulnerable refugees and offer some stability in the region.”

Casey sent a letter Tuesday to Senate Appropriations Committee leaders Barbara Mikulski (D-Md.) and Richard Shelby (R-Ala.) requesting they consider increasing the amount of aid provided to the region if possible.

Casey said more than 600,000 Syrians have fled their country to neighboring Jordan as a civil war wages on between the regime of Syrian President Bashar Assad and rebels who oppose him.

“Jordan has offered these Syrians a refuge from the fighting at a time when their own economy is still feeling the effects of the global financial crisis,” Casey wrote. “Therefore, I urge Congress to fully fund the president’s [fiscal year 2015] request for assistance and consider additional funds if possible.”
