Now, we turn to the shocking revelations shaking up the new york mayor's race one more time. Anthony weiner claimed to be a changed man. But the sexting did not stop. In a news conference late yesterday, weiner said that wouldn't push him out of the mayor's race. And jeff, his wife there to back him up. But three of his opponents and two major newspapers saying, enough is enough. That's right, george. It was an extraordinary scene. It was a human drama when his wife stepped ford to deliver a public testimonial in hopes of stopping her husband from another political free-fall. I said that other texts and photos were likely to come out. And today, they have. Reporter: The scene was familiar. Anthony weiner, back in front of a microphone, admitting involvement in another sexting scandal. There's no question that what I did was wrong. Reporter: What's different, though, is that he's no longer a congressman. He's running for mayor of new york city. And this time, his wife, huma, hillary clinton's former aide, is standing by his side. And speaking out. I'm very nervous. I wrote down what I wanted to say. I love him. I have forguinn him. I believe in him. And as we said from the beginning, we are moving forward. Reporter: His fall from grace was extraordinary. A congressman forced to resign two years ago, from sending sexually explicit messages to women. And tuesday's revelations could spell new trouble for his candida candidacy. The e-mail messages were explicit and x-rated. I hear liberal girls are very, uh, accommodating of others. His rivals and others are calling for him to leave the race. But huma is deg her man and his candidacy. It was not an easy choice in any way. But I made the decision that it was worth staying in this marriage. I do very strongly believe that is between us. Reporter: And he is asking for, yet, another chance. Let me just reiterate to my wife, how sorry I am that I did these things. And how sorry I am to the people that got these messages. Weiner was in the thick of the race before the new revelations. Whether voters are going to give him a third chance. But this seemed to surprise to those closest to the campaign. Reporter: It did. And it surprised those closest to the family. Friends close to the family said that huma was shocked and saddened by this. You could see that look on her face. The biggest problem is the timeline of this. This happened six months after their son was born. The son was born in december of 2011. The texting was going on until june 2012. That's the sticking point that hurts this family. Jeff, thanks very much.
