Republican lawmakers in the U.S. have been arguing for months that opening the door to thousands more refugees would be akin to having a welcome party for Islamic militant terrorists.
At a congressional hearing in February, both the FBI and the director of the American National Counterterrorism Center acknowledged there could be a risk, with the FBI suggesting there wasn't enough information available on the ground in Syria to properly vet cases.
And in June, a U.S. researcher reminded Congress that two failed terrorists attacks against the U.S. were organized by people who'd sought refugee status in Canada first.
