Maybe something like:
I was amazed that this was brought up. And very surprised that the other side decided to release that tape of me of saying some things that I am ashamed of. As I have said, I am far from perfect. I do have my strengths, but there have been times in my life I have let my success go to my head and have behaved like a jerk. I really wanted to just get on from personal matters to the business of our country, which is more important for the working families struggling to make ends meet. But now that the personal issues are brought up, like I was hoping they would not be, I can't sit idly by anymore and not point out the absurd hypocrisy of a woman who has a long history of slandering the good names of women who were innocent victims of her husbands sexual harassment, sexual assault, and even rape. The kind of behavior I engaged in was the kind one ought to feel ashamed of an apologize for. The kind she engaged in, is just so, unmentionable in front of children, that one doesn't just apologize and move on. And I was really hoping we did not have to mention it...I have to ask that parents watching the debate at home may want to have young children leave the room before I continue giving voters some background about Hillary that the liberal press is not going to tell you...
