NEW YORK (CNN) – CIA Director John Brennan says the U.S. government is doing its best to prevent terror activity in the country.
He admitted the likelihood of such activity remains strong and says authorities must continue to remain proactive on the terror front.
“I think any good counterterrorism professional, and I know I’ve had conversations with Jim Comey in the FBI. You cannot assume that there is anybody in the homeland. What you need to do is to be able to continue to uncover and use intelligence. What they might be doing here. Who’s in contact with whom. And their operational security is really quite advanced and they make it difficult for law enforcement and intelligence to identify them. So I think we have to assume that there is something here in the states,” CIA Director John Brennan said.
Brennan also said he is confident the U.S. will break down the senior leadership of the terror group ISIS.
Although he admits it’s impossible to say whether isis has operatives or cells working in the U.S.
