In front of several staff members, the woman who had endured grueling treatments for breast cancer took off her shirt and bra, exposing her chest.
" 'You don't see me anymore,' " Reynolds quoted Elizabeth Edwards as screaming. "He didn't have much of a reaction."
As staffers scrambled to cover up Edwards' wife and huddle her into a car, Reynolds heard the Democratic candidate use a cellphone to call his wife's doctor to ask for help.
Edwards then boarded a waiting jet and took off for his scheduled appearance in South Carolina, Reynolds said.
She testified that Elizabeth Edwards had known about her husband's affair with Rielle Hunter before the National Enquirer made it public in October 2007. Hers was the most stirring testimony of the day at Edwards' trial on corruption charges, as prosecutors worked to build a timeline of the affair and efforts to cover it up.
Shortly before Reynolds began her account of that day at the Raleigh airport, Edwards turned to his daughter Cate, seated in the front row for much of her father's trial.
"I don't know what's coming," Edwards was heard saying. "Do you want to leave?"
She responded to him in a whisper, grabbed her purse, and walked out, wiping away tears. Edwards was heard saying, "Cate, Cate" as she left. She returned to court about a half-hour later, after a brief recess.
Reynolds, 37, had worked on Edwards' successful U.S. senate campaign in 1998 and had quickly bonded with his wife.
