Former State Department official Walter Kendall Myers, 72, and his wife, Gwendolyn, have pleaded not guilty to charges of spying for Cuba.
The couple was arrested last week and accused of spying for the Castro regime for nearly 30 years.
Mary Beth Sheridan, diplomatic correspondent for The Washington Post, says those who knew the Kendall Myers are in shock.
"They said, 'It's like they had arrested Santa Claus and the Easter Bunny,'" she says. "Nobody could have imagined this delightful couple as being spies."
