"The heinous terrorist attacks in Paris and Beirut, in Iraq and Nigeria. They showed us once again the depths of the terrorist's depravity," he said.
"And at the same time we saw the world come together in solidarity. Parisians opening their doors to anyone trapped in the street, taxi drivers turning off their meters to get people home safely, people lining up to donate blood," he said.

"Let's set the record straight how it works for a refugee to get asylum. Refugees face the most rigorous screening of anyone who comes to the United States," he said.
First they are finger printed, then they undergo a thorough background check, then they are interviewed by the Department of Homeland Security.
And after that the FBI, the National Counterterrorism Center, the Department of Defence and the Department of State, they all have to sign off on access, he added.
"There is no possibility of being overwhelmed by a flood of refugees landing on our doorstep tomorrow. Right now, refugees wait 18 to 24 months while the screening process is completed. And unlike in Europe, refugees don't set foot in the United States until they are thoroughly vetted," Biden said.
