Sen. Bob CaseyBob CaseyDem leaders amp up calls for bipartisan ObamaCare fixes Let’s not roll back bipartisan progress on global food security Vulnerable senators raise big money ahead of 2018 MORE (D-Pa.) told Senate appropriators to fully fund President Obama’s budget request for air to Syrian refugees in Jordan.

“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.”
