Former President Jimmy Carter believes U.S. intelligence agencies are spying on him — so much so, he eschews email to avoid government spies.

"You know, I have felt that my own communications are probably monitored," Carter told NBC's Andrea Mitchell in an interview broadcast Sunday. "And when I want to communicate with a foreign leader privately, I type or write a letter myself, put it in the post office and mail it.

"I believe if I send an email, it will be monitored," Carter continued.
