Transcript for Top Military Commanders to Testify on Sexual Assault
We'll stay in washington where all the military's top commanders will face congress together today. The issue, an epidemic of sexual assaults in the military. An estimated 26,000 last year. Martha raddatz is covering the confrontation. Martha, this will be dramatic for the first time, seven members of that senate armed services committee are women. Reporter: They are, indeed, george. Just think about the optics alone here. All of the top officers, those service chiefs and chairman of the joint chiefs are men and they will face that powerful group of female senators. I suspect the chiefs are in for a real grilling. The chiefs have taken the issue seriously and made very strong statements in the past. But the senators are clearly going to say, this just isn't working. Look at those numbers. Martha, these chiefs are very reluctant to give up their power to investigate sexual assaults and the top legislation being considered root now would turn that over to prosecutors. Reporter: Well, the commanders -- the chiefs say the commanders need to be the ones that keep so-called good order and discipline but I think you will hear not only the senators saying there has to be a different approach because victims are ao report to their commanders, but we know some victims of sexual assault will be on the hill. One in particular who was raped and drugged saying take this out of the hands of commanders it could be a very dramatic day. That will be powerful change is coming here. Reporter: I believe it is. I believe you will see some sort of change. Maybe not with those female senators want but something has to change. Okay, martha raddatz, thanks very much.
