Attacks on donald trump to a whole new level. For the first time, she called him a fraud for allegedly ripping off students at his Trump University. He denies doing that. A new poll out today shows clintons lead over trump nationally is just four points. But, remember, its not the popular vote that wins. The president ial election is a statebystate battle for 270 electoral votes. Heres nancy cordes. This is just more evidence that donald trump himself is a fraud. Reporter newly released federal Court Documents gave clinton all the ammunition she needed. You cant make this up. Reporter she quoted managers at the nowdefunct Trump University who said the real estate schools Business Model was a total lie that preyed upon the elderly and uneducated. Trump and his employees took advantage of vulnerable americans, encouraging them to max out their credit cards, empty their retirement savings, destroy their financial futures, all while making promises they knew were false from the beginning. Reporter taking a page from trump, clinton kept up the assault online with a barrage of tweets calling trump u. , a con that intentionally put people at risk. Ill win the Trump University case. Reporter but trumps not the only candidate being scrutinized by federal authorities. Clintons email server is the focus of a longrunning f. B. I. Investigation. In a new National Quinnipiac poll, both candidates get low marks for honesty, though trump does slightly better. I want to have an intervention. laughter reporter speaking in indiana today, president obama went after trumps plan to lower taxes for the wealthy. That will not bring jobs back. That is not fighting for the american middle class. That will not help us win. That is not going to make your lives better. That will help people like him. Reporter trump is not the type to let an attack go unanswered, and this evening, he has taken to twitter saying, crooked Hillary Clinton is a fraud who has put the public and country at risk by her illegal and very stupid use of emails. Many missing. In other words, scott, i know you are, but what am i . Pelley nancy cordes reporting tonight. Nancy, thank you. Well, Trump University never had a campus. It started in 2004 as a series of seminars to teach real estate investing. Students paid 1,400 for three days, and then were pressed to pay 35,000 to get tips from trump himself. Nearly 7,000 students signed up. Three years ago, the new York Attorney general and students in california sued. Chief Legal Correspondent jan crawford is following this case in federal government. Reporter on the defensive, donald trump has taken aim at the judge. The judge has been very unfair, has not done a good job. Hes been a very bad judge, he has been very unfair. Reporter trumps even brought up judge gonzalo curiels ethnicity. The judge, who we believe to be is mexican, which is great, thats fine. Reporter curiel, who was born in indiana, has now turned the tables, ordering the ntcuments in the case released noting trump placed the integrity of these Court Proceedings at issue. The documents, confidential playbooks, gave University Employees tips on the psychology of the sale, urging them to use personal information to identify and recruit Prospective Students easily swayed by hopes of financial gain. One example are they a single parent of three children that may need money for food . Potential students were invited to free workshops where they were pressed to take additional courses, one costing almost 35,000. Before closing in 2010, Trump University promised to teach students the real estate tycoons investment techniques. Thats what its all about success. Its going to happen to you. The courses that i took were outstanding. Reporter today, the Trump Campaign released this video of three students who say they are successful in business because of what they learned at trump u. But thats not what former Trump University student gary smith told cbs news. I didnt get any financial gain. Its been a bigtime net loss at this point. Reporter now the judge is now trying to roll back his order, saying he mistakenly ordered some documents released that contain personal information on the students, like their home addresses. About 40 of the students, scott, have asked for a refund. Pelley jan crawford in the washington newsroom. Jan, thank you. Well, students in a Real University barricaded themselves in their classrooms today. Hundred of Police Officers stormed the university of california los angeles after reports of an active shooter. Turned out to be a student and a professor who died in a murder suicide. Ben tracy is there for us right now. Ben. Reporter scott, this is the Engineering Building here where the shooting happened today, and weve just confirmed that the professors name was william klug. As you can see, there is still quite a Police Presence here tonight but this is nothing compared to what it looked like here earlier this morning. The Law Enforcement response to this was simply massive. You had hundreds of l. A. P. D. Officers swarming this campus with automatic weapons. You had the f. B. I. , the a. T. F. , and 17 ambulances that were sent here. Now, that is in large part because this is such a huge campus. 419 acres on the middle of the west side of los angeles where more than 30,000 students go to school. Now, most of those student were on lockdown for about two hours. From social media, we could see some of the ways they tried to protect themselves. Some students used an extension cord to actually tie their door shut. Other students used a printer and a foosball table to barricade their door. Now, obviously, this did not turn out to be a mass shooting. This turned out to be a murder suicide, and the motive for that at this point, scott, is still unknown.

Pelley for as long as people have been putting money in wallets, pickpockets have been stealing them. But technology has changed that game. Heres don dahler. Reporter two suspects were captured on Bank Surveillance video withdrawing money using stolen credit card information. Last month, thieves at Walmart Stores in virginia and kentucky used skimmers, devices placed over credit card readers, to gather information and pin numbers and make duplicate cards. A skimmer works by recording the Digital Information from a swiped card, and a microcamera captures the pin number. Those are sent to the thief via bluetooth or removed later. In this security video, the man on the right shields his partner who pulls the skimmer out of his jacket and pops it in place. The whole operation . Two seconds. They made off with as much as 20,000 from at least 38 victims. Michael seremetis is with the secret service, the agency which investigates these types of crimes. They would download the information and put it on a duplicate card, either a gift card or another credit card they had. Where they would download the information on to this magnetic strip. And then they have your credit card and can use it for any type of fraudulent purchases. Reporter the devices are identical to the real things and have plagued gas stations and a. T. M.

Reporter walmart now requires customers to use special chipenabled cards, more secure because theyre not swiped, but 30 of credit cards dont have them and only 20 of card terminals are compatible. The secret service says you can protect yourself by always covering the keypad with your other hand when you enter the pin.
