President Barack Obama said U.S. intelligence and counterterrorism officials don't have any specific, credible information suggesting a potential terrorist attack against the country during the holiday season.
Obama delivered an update on the U.S. fight against terrorism during a visit at the National Counterterrorism Center in Virginia, where he received a Thursday briefing.
"We are in a new phase of terrorism, including lone actors and small groups of terrorists like those in San Bernardino. Because they are smaller, often self-initiating, self-motivation, they're harder to detect, and that makes it harder to prevent," said Obama. "But just as the threat evolves, so do we."
