The race for the white house and more fallout from that big victory even as sources in his own campaign tell abc news hes to blame for what went wrong monday night. Abcs tom llamas is at trump headquarters. Pretty extraordinary fingerpointing getting criticized by his own staff. Reporter this is a blame game like weve never seen with the Trump Campaign and it comes at a time that Hillary Clinton is launching a full frontal assault. She was campaigning with senator Bernie Sanders yesterday. Michelle obama out by herself hitting trump hard and the fallout. This morning, trouble inside the Trump Campaign. Fingerpointing at the highest levels about trumps rocky debate. In an explosive admission, a senior aide telling abc news, the lions share of the plame rests with one person, donald trump. That aide saying, quote, trumps debate failures stem from more a lack of execution than preparation. And he left a lot of things on the table. He pulled his punches, lost his nerve. Victory citing unscientific polls. I had a great time and i know you say the polls werent scientific but every single poll that was taken i won the debate and some of them by a lot. Reporter top aides disagree including about what went wrong. Some argue he didnt prepare enough and that there were missed opportunities including not mentions benghazi, trump himself says he showed restraint at the debate when it came to bill clintons past affairs. I was also holding back, i didnt want to do anything to turning up the heat on clinton. Bringing up that video outside the 9 11 memorial when clinton almost collapsed. You see all the days off that hillary takes. Day off, day off, day off. All those day offs and then she cant even make it to her car. Isnt it tough . Reporter First Lady Michelle Obama taking on trump in the important battleground state of off or lash out irrationally. No. We need an adult in the white house. Reporter urging people to get out and vote for Hillary Clinton. Who spent 11 hours testifying before a congressional committee. Can i get an amen. Hillary is tough. Reporter now, back to the debate prep for a moment. So that first debate, Rudy Jude Annie played a major role in it. Chris christie to help out with the second debate. Okay, tom, while i have you newsweek out a few minutes ago with a brandnew cover story talking about how donald trump and his companies broke the cuba embargo by funneling money through a consulting firm. Pretty exclusive charge right there. What is the Trump Campaign saying about it . Reporter right now the Trump Campaign has no comment but that investigation alleges that the Trump Corporation reimbursed consultants to go into communist cuba and explore casino opportunitie business undertaking by itself violated the embargo but the big contradiction here is that trump then and now says he would never do business with a castro regime. George. Well see what they say later. Lets bring in matthew dowd for more. I have to start with that quote in toms piece. A candidate staff saying he lost his nerve during the debate. Ive never seen anything like it. Youve been inside the top levels of campaigns. Take us inside their staff meeting this morning after Something Like that comes out. That. I think that donald trump obviously weve seen it transition from various campaign managers, now on their third set of leadership. To me what it looks like is somebody hasnt been able to give him the advice or him take the advice so what theyre now trying to do is try to get him the advice through doing it exte externally and doing it publicly. I dont think its going to help but thats the only explanation i can have for why they did this. This newsweek cover story, you saw Hillary Clinton try to put trumps Business Record on more charges here. Does this cut . I think the problem with this its an accumulated wait so every time theres a story that goes to a problem that hes got in his business, it just weighs on the American Public who then finally comes to the conclusion that says i cant trust this guy. I cant trust his business background. The other part of the story, this is about the cubans, right, and the cuban vote in florida is very important for him if hes going to carry florida. If they think that he was somehow cutting a deal with for him. Meantime, you saw that quote from Michelle Obama last night. Pretty fiery speech in pennsylvania. You had president obama out yesterday saying any vote thats not for Hillary Clinton is a wasted vote even if youre voting for gary johnson or jill stein. They have a direct case to millennials. They had a concerted plan going into that debate and coming out of that debate. Not only from the . Freepress they got stories but surrogates hit the trail in the aftermath and some of the most popular surrogates, undecided voters in this race a most popular people among undecided voters and partisans are president obama and Michelle Obama and theyre now out and about. Matthew, one more question, if youre donald trump and watching obamas on the trail, other people have influence speaking out for hillary how do you go headtohead with that. I think it would be problematic for him to try to sort of scurry around and find surrogates of his own. I would practice it like judo, use their weight against them and basically say im here standing alone and thats all against you and the public so if you want to get rid of the status quo which is them vote for me whos the singular leader. And once again, she never Michelle Obama never mentioned him by name. She is the best at surgically going through that and doing it in a way that you start nodding and never hear Donald Trumps name but you know exactly what shes talking about. New concerns about hacking and the electric. The fbi director saying hacke into multiple states voter databases. Abcs senior justice correspondent Pierre Thomas is in washington with these breaking new details. Good morning, pierre. Reporter good morning, robin. Abc news learned u. S. Authorities suspected hackers affiliated with the russian government have tried to infiltrate the Voter Registration databases of at least 15 states and sources briefed on the investigation tell us at least 4 states actually had Voter RegistrationComputer Networks breached with hackers snooping around and possibly copying information on hackers would want to do those, right .
