A number of California airports increased security measures over the weekend after intelligence officials intercepted messages about a possible terror plot against the United States.

The Department of Homeland Security did not release details of the threat other than saying they had intercepted chatter and other information that raised concerns.  They also confirmed the chatter was connected to ISIS.

“Over the last few months, we have made a number of security adjustments, including enhanced screening at select overseas airports and increasing random searches of passengers and carry-on luggage on flights inbound to the U.S., reflecting an evolving threat picture,” a spokesman with the department told CNN.

In addition to the airport security upgrades, DHS confirmed they had been increasing security at federal installations since February.

“The department has conducted significant outreach efforts … with state and local law enforcement partners regarding these trends and engaging in a series of meetings and events with local community leaders across the country to counter violent extremism,” the spokesman stated.

The TSA alerted local law enforcement that the airlines might not be the target but rather an individual actor focusing on uniformed personnel at various locations.

The increase in DHS actions and security comes after the head of the FBI admitted they have intelligence of people in all 50 states with sympathy toward the terrorist organization ISIS.

“Those people exist in every state” Comey said at a law enforcement event. “I have homegrown violent extremist investigations in every single state. Until a few weeks ago there was 49 states. Alaska had none, which I couldn’t quite figure out. But Alaska has now joined the group, so we have investigations of people in various stages of radicalizing in all 50 states.”
