(CNN) Former Director of National Intelligence James Clapper suggested Thursday that President Donald Trump's threat to revoke security clearances was being leveled against an "enemies list" of those in the intelligence community who have been critical of his administration -- not those who have committed any wrongdoing.

"It is an enemies list to get at people that have been critical or who have taken actions that, you know, he didn't like. That to me is a pretty chilling message," Clapper told CNN's John Berman on "New Day."

The former intelligence chief said that someone's security clearances are typically only put in jeopardy "if they mishandle or divulge classified information."

"I don't think there's been any evidence of that presented at all -- haven't had access to it," he said.

Clapper, a CNN analyst, also pointed to the fact that there were no Trump allies on the list of people from whom the President is considering revoking clearances. That list includes Clapper himself, former FBI Director James Comey, former CIA director and National Security Agency chief Michael Hayden, former deputy attorney general Sally Yates, former national security adviser Susan Rice, former deputy FBI director Andrew McCabe, former FBI officials Lisa Page and Peter Strzok, and Bruce Ohr, a current Justice Department official.
