paul agrees and the deadline is 11 hours from now. we'll keep you posted. >>> now to a high-profile murder trial in florida. there were some tense and heated moments today in the murder trial of casey anthony. as the defense questioned a key witness. casey anthony's father. the 25-year-old florida mom is accused of killing her 2-year-old daughter caylee nearly three years ago. let's get straight to what's happening right now in court. "people" magazine staff writer steve helling joins me by phone for orlando where he has been watching every moment of this case very closely. steve, casey's anthony, took the stand. he is a key witness, we know. the defense earlier this week accused him of sexually assaulting casey and says that he saw caylee fall into the pool. but anthony seemed at times a bit testy and denied a lot of claims made by the defense so what did we really learn from him on the stand today? >> well, the first thing we learned, which was interesting, was that there's no love lost between george anthony and casey's attorney, jose baez. they glared at each other the entire time. it was ugly, it was tense. but we didn't really learn much about what had happened on the day tha
