WASHINGTON -- CNN's John King says he is embarrassed after wrongly reporting last week that a suspect in the Boston Marathon bombings was arrested, calling the mistake a "double kick in the head" because he's a Boston native. "When you do something like this, it's embarrassing," King, the network's chief national correspondent, told WTOP on Tuesday. "The one thing you have to do is look straight in the camera and say, 'We were wrong.'"
