U.S. Senator Charles Schumer doesn't want to see the U.S. open its borders to refugees without a thorough background check, he said Monday.

The U.S. has committed to take in at least 10,000 Syrian refugees fleeing the war-torn region, but while President Barack Obama reiterated Monday his call not to reject the refugees, critics say it could be a risk to national security following the terror attacks in Paris last week. 

A Syrian passport was found near the body of one of the Paris suicide bombers.

"I think we have to check and see if we can determine, distringish the would-be terrorist, from the regular people before we let them in," Schumer said.

Rep. Chris Gibson said in a statment, "The U.S. should immediately suspend its Syrian displaced person support program until we know more about what happened in Paris and until we can assure the safety and security of our people.”
