To ensure the defeat of ISIS, Congress must pass new laws on gun ownership, President Obama said in a primetime address Sunday.

“Now, here at home, we have to work together to address the challenge” of terrorism, Obama said, after outlining four measures the U.S. will take against ISIS. He continued:

To begin with, Congress should act to make sure no one on a no-fly list is able to buy a gun. What could possibly be the argument for allowing a terror suspect to buy a semiautomatic weapon? This is a matter of national security.
We also need to make it harder for people to buy powerful assault weapons like the ones that were used in San Bernardino. I know there are some who reject any gun-safety measures, but the fact is that our intelligence and law enforcement agencies, no matter how effective they are, cannot identify every would-be mass shooter, whether that individual is motivated by ISIL or some other hateful ideology. What we can do and must do is make it harder for them to kill.
