Following a 12-week maternity leave, Elizabeth Vargas will return as co-host of ABC's 20/20 with a feature about the plight of working mothers, the Washington Post reported today (Wednesday). According to the newspaper, she will describe her own experiences as well as those of three other working women with children. Vargas continues to deny that she was forced to leave ABC's World News because of her condition, insisting that the decision for her to step down was a mutual one. "Having had the baby, I can't imagine going back to that demanding job right now," she told the Post.
