Obama: Terrorism an 'Evolving Threat' U.S. Will Overcome

Obama addressed the nation on the San Bernardino shooting and terrorism Sunday.

"The threat from terrorism is real, we will overcome it," Obama said. "We will destroy ISIL and any other organization that tries to harm us."

While both are unlikely with the Republican-led Congress, the administration has worked with lawmakers on tightening security in the visa waiver program, which allows individuals with passports from 38 countries to travel to the United States without a formal visa.

The House will vote this week on a bill to add additional security requirements to that program.
