One man having a tough super bowl. Chris Christie bad in times square overnight. This as he's taking a hard and personal run at a former staffer who's accusing the governor of lying about the bridge-gate scandal that's engulfed the administration. He was once dubbed the eyes and ears for Christie at the port authority, but David wildstein is wiping the mud of a his face slung by Christie's office. You have heard enough speeches of the same thing. Wasn't the super bowl weekend welcome New Jersey governor Chris Christie wanted. Now Christie is on the attack. Taking aim at former ally and transportation official, David wi wild teen whoing as there's proof he knew about it. The governor's office went after him, claiming a controversial tenure as mayor of Livingston who made moves not productive. He piled on the political power, and he highlighted what was wild stein's credibility. And from the 70s, and accused of deceptive behavior by his high school social studies teacher. He will do anything to save himself. But now wondering how he's attacking so aggressively the man he trust and the put into a position of power. Much like the game on this field, the psychological warfare can't be ignored, much like the ads -- some think the damage is done. They want this was the crowning achievement. Kick off the presidential campaign essentially at the super bowl. And the latest attack of him says that as a 16-year-old he sued, and he was an anonymous blogger known as wally edge and I'm quoting, had a strange habit of registering web addresses for other people without telling them. It's getting personal. Really personal. Let's talk more with George stephanopoulos. Good morning. Rita raised this question, but how effective are the attacks likely to be given he hired him in the first place? It depends on what he has. Remember the letter from the lawyer, evidence exists that he wasn't telling the whole truth. Doesn't necessarily say he has the evidence. It's all going to come down to what his testimony is to all these investigations and whether he can prove that Christie wasn't telling the truth. He was seen as a front-runner for 2016. Yesterday we had Matt dowd on the show, and he said him being president is the same as Amanda Knox going on vacation in Italy. There's no chance he's going to vacation in Italy. Chris Christie, it's going to depend on the next year. He's going to be tied up in the investigations. If he's not telling the truth, he's done. But gets through the investigations, rebut the allegations, he can get back into this. The republican field is a muddle. Three months ago, he was the front runner. Now part of the pack, but not out of it. Interesting perspective. And a question that bianna was asking at the break, if one of the perceived problems is that he's a bully, why put out a memo that seems he's bullying him, bringing things up from when he was 16 years old. ; I was surprised. But shows the potential damage of the charges. When he's saying he didn't tell the truth at the press conference, that's an incredibly damage, possibly fatal charge. They have to muddy up his credibility. But I was surprised they went back to high school. Clearly not the way he wanted to spend super bowl weekend. Not the boos last night. Thanks, George. And George will have much more on ABC's "This week." And now to Ron Claiborne. High bianna golodryga and Dan Harris.
