NEW: Text messages obtained by TMZ are raising new questions in a sexual assault case at Cornell University, where a woman has accused seven men of rape. @​BryanLlenas reports the woman initially sent messages suggesting the encounter was consensual, but two weeks later told one of the men that "90% of what happened that night was not consensual." Her attorney confirms the messages are authentic, arguing her changing account reflects "classic symptoms of delayed recognition" following sexual assault. ▻
