"No, I have not," Brennan told Chuck Todd on NBC's "Meet the Press." 

Brennan added that he was not surprised that Mueller has not yet reached out to him. 

"I think Mr. Mueller would have had access to CIA files that he needed. And, again, CIA's role is not to look at the activities of individual Americans by any means. But I think there's a full record there and there are individuals at the agency who can provide the insight to Bob Mueller's team that they need," Brennan said.
