| A sperm donor's lies are sparking fears among the parents of his biological children. A lawsuit filed in California Monday alleges that Xytex, a Georgia sperm bank, misled couples about their sperm donor. The suit claims the company did not disclose his mental illness and a criminal record. He allegedly fathered at least 36 children. CBS News legal expert Rikki Klieman joins "CBS This Morning" to discuss the case.
