Michael Vick admitted on Tuesday night that he lied to his mother about his dogfighting past. "I lied to my mom," Vick told CNN's Piers Morgan. "She really didn't know what was going on. She I think had heard just from people word of mouth that I was engaging in illegal activity but she couldn't put a finger on it and nobody else knew. "I told her the truth the day I got arraigned. I think my mom cried for four or five days straight, and everybody else around me who loved me and cared about me, because they just didn't think it would go that far -- they didn't think I would end up going to prison. It was a dramatic change for everybody's life."
