A former aide to Edwards was testifying Wednesday about an argument Elizabeth Edwards had with her husband on the day in October 2007 that a tabloid published a story about his affair.
In court on Wednesday, Edwards turned to his daughter Cate as witness Christina Reynolds was beginning the account about the argument at the Raleigh airport.
Edwards was heard asking his daughter if she wanted to leave. She responded inaudibly to him, then walked away wiping her tears. Edwards was heard saying, "Cate, Cate" as she walked out.
Edwards has pleaded not guilty to six criminal counts related to payments from wealthy donors that were used to conceal his mistress and the child they had.
