In a pre-recorded interview, former President Jimmy Carter said he corresponds with foreign leaders the old-fashioned way, through "snail" mail, out of privacy concerns.

He said, "I have felt that my own communications are probably monitored. And when I want to communicate with a foreign leader privately, I type or write the letter myself, put it in the Post Office and mail it, because I believe if I send an email, it will be monitored."

Carter added that he thinks the National Security Agency’s electronic surveillance and the United States’ use of drones "has been extremely liberalized, and I think abused, by our own intelligence agencies."
