Capital one didnt know about it until a member of the public alerted authorities via email saying they saw the alleged hacker talking about the stolen information online. This morning a 33yearold former Software Engineer from seattle is accused of stealing a vast amount of customer information from one of the nations biggest credit card issuers. According to a criminal complaint, paige a. Thompson obtained the data by accessing a server rented by capital one and then posting it to an information sharing site.

It is a big night in politics, the crowded field of democratic president ial candidates will face off during tonights start of the second primary debate. Its happening over two nights in detroit, and this morning weve got results from a new poll on the race. Weve got two reports for you. Well start with nbcs Morgan Radford who has been talking to those critical state voters. Reporter that new National Poll shows front runner joe biden expanding his lead. We can expect to see more fireworks tonight as the other candidates really sharpen their attacks against him and look for breakout moments to stand out from each other, but in this case, where they are speaking could be as critical as the policies themselves. Detroit is still a solidly blue city in a state that flipped red for trump in 2016. I spoke with voters who say theyll be tuned in and warn that none of the candidates should take their votes for granted. Reporter ahead of tonights make or break debate in the motor city, joe biden is still dominating the democratic race. A neuqupoll shows the former vi president with a doubledigit lead over his rivals surging 12 points in the past month. Bidens closest competitor senator Elizabeth Warren with 15 followed by senators Kamala Harris and bernie sanders. For biden, its a dramatic turn around following his rocky performance in that first debate. Caught offguard when harris targeted his Senate Record on civil rights. You also worked with them to oppose busing. Reporter now the former Vice President says hes ready for a rematch telling democratic donors last week im not going to be as polite this time. I will express differences and articulate them and certainly point out where we have differences of opinion. Reporter and for tonights debate, the location is just as key as the lineup. Michigan is one of three critical swing states along americas manufacturing corridor that flipped for trump in 2016. Voters here say they want to hear about the economy. Bring in more jobs, it will be good for the community. Reporter at a local gym in detroits northwest side, in an historically black neighborhood, voters say the candidates shouldnt take their votes for granted. What do you think detroit needs to hear from these Democratic Candidates . I think we are more concerned about hearing not just the middle class, but the black middle class. We are the motor the motor city, but even those jobs are decreasing, so its like whats next . Weve been talking to folks. Are they enthusiastic about any particular candidate or still doing the wait and see . Kind of the wait and see. What we saw on the ground did largely confirm what we saw in that poll. Its interesting to see how much these debates matter to voters. One person said he liked buttigieg because he felt like he answered honestly. Others felt like biden is the only one who can really take on President Trump. Others felt like sanders when it came to education and mass incarceration was something that is important to them. Its still early. Still a lot of candidates. Thank you, morgan.

Reverend sharpton what is your message to President Trump . He should not continue to try and sell this racist behavior to try and make the country more divided for his own political gain. Hes trying to say its us versus them. That is not reflective of a leader and certainly not an american leader. Reporter even nfl coach John Harbaugh was asked to respond. We love the people in baltimore everywhere, maybe its because the baltimore people love the ravens so much. Weve felt nothing but love here for the last 11 years. President trump has dechblded himself as aides argue hes fighting back against an antagonist in congress. Cummings chairs the house Oversight Committee. Now after then kand daytoday tru candidate trump pledged on the campaign trail to help lift up urban neighborhoods. What the hell do you have to lose .
