What Warren & Sanders said in tense post-debate exchange

I also believe a woman cannot win against President Trump, its true they cant, why fight why dispute what is the truth, Bernie didnt say a woman can never become president, he said at this time a woman cannot defeat President trump, and he is right, why is she making such a big deal out of it and making a scene I dont understand, wasnt a good move, not at that stage at least, doesnt look good.
