Wendy Casey acknowledged that her rivalry with her son does not reflect well on the family.
"It makes both of us look bad, like we're both playing political games. It's bad with our family because they can't show favoritism," she said. "They said someone should step back and he refused to do it, but I raised him to be a strong-minded independent thinker so this is what happens."
