President Obama used part of his speech Tuesday to renew calls for gun control, warning that failing to enact new gun laws will allow San Bernardino- and Orlando-style terrorist attacks “to keep on happening.”

“If we really want to help law enforcement protect Americans from homegrown extremists—the kind of tragedies that occurred at San Bernardino and that now have occurred in Orlando—there is a meaningful way to do that. We have to make it harder for people who want to kill Americans to get their hands on weapons of war that let them kill dozens of innocents,” Obama said.
