FBI admits there's no way to screen all the Syrian refugees the Obama administration plans to accept into the US

FBI Director James Comey on Wednesday told Congress that the federal government cannot conduct thorough checks on all of the coming influx of 10,000 refugees from Syria.

Appearing before the House Committee on Homeland Security, Comey said Syrians who aren't already in the FBI's database are unknown to the agency, meaning their backgrounds cannot be adequately scoured for a risk of terrorism.

'We can only query against that which we have collected,' Comey told the committee under questioning.

'So if someone has never made a ripple in the pond in Syria in a way that would get their identity or their interest reflected in our database, we can query our database until the cows come home, but there will be nothing show up because we have no record of them.
