Agent manny gomez calls a tsunami of potential threats. Do you think there are people who are being missed . Absolutely. The f. B. I. Does not have the resources, both legally and in terms of manpower and funding. These people are being radicalized quicker than we could identify them. Reporter in rahamis case, despite his father calling him a terrorist in 2014, and his year long stay in pakistan, an f. B. I. Source says at the time it found nothing in its indicators, such as links to other known terrorists or radicalized behavior, to point to rahami being a terror threat. Since 9 11, the Homeland SecurityCommittee Says there have been at least 166 home grown jihadist plots in the u. S. , including attempts to join terrorist groups overseas and execute attacks at home, an average of 11 per year. Just this year alone, 26 people in the u. S. Have been arrested in 13 states for isisrelated activities including plots to attack, Financial Support and weapons charges. Sometimes there are clues, but to make a case, authorities need evidence that they often do not find. The orlando pulse nightclub shooter, omar mateen, had been on the f. B. I. s terrorist watch list for ten months and was investigated but later removed from the list. In june he killed 49 people. Cbs news consultant Fran Townsend says the system needs improvement. You want the terrorist watch list to be overinclusive, so if there is somebody you think may be but you dont have enough, you want it to alert other agencies to put more information in that might push you over the edge. Reporter since 2014, authorities have arrested 105 people in the u. S. Scott, they say those people were plotting attacks, attempted to join isis, or provided money, equipment or weapons to that terror group. Pelley anna werner, thanks.

God, i ask that you would touch this man, donald j. Trump. Reporter trump was introduced and partly overshadowed by former boxing promoter don king, who used a racial epithet while describing discrimination against African Americans. If you are dancing and sliding and gliding i mean negro, you are a dancing and sliding and gliding negro, so dare not alienate because you cannot assimilate. So, you know, you going to be a negro until you die. Reporter the effect was unsettling and symptomatic of trumps pitch to African Americans, one hes made largely to white audiences. Trump has also turned down speaking invitations from the n. A. A. C. P. And other civil rights groups. Yesterday in north carolina, trump said this about the state of black life in america.

Congress demanded to know why the cost of the lifesaving treatment for allergic reactions is up about 500 . Heres vinita nair. You put it out of reach of the average consumer. Reporter mylan c. E. O. Heather bresch faced bipartisan backlash for her companys pricing and revenue strategy. I wish we had better anticipated the magnitude and acceleration of the rising Financial Issues for a growing minority of patients. You never anticipated it . You raised the price. What did you think was going to happen . Reporter since 2009, the price of epipens has slowly increased from about 100 for a two pack to more than 600. The 47yearold tried defending the spike by saying the company only makes 100 for every two pack after cost. Committee chairman republican jason chaffitz. When the juice is 1 and youre selling it for 600, theres room for profit. Reporter mylan has been the focus of public scrutiny since families complained about skyrocketing costs. In response to the criticism, the company increased the value of coupons to families and has announced a 300 generic version of the drug. For lexi hennigers family, their 1,200 pharmacy bill for two kids was cut in half by the coupon. But it wasnt quite what we were looking for from the company. We were hoping they would lower the overall price. Reporter lawmakers on both sides of the aisle agreed. Democratic congressman elijah cummings. Im concerned that this is a ropeadope strategy. After mylan takes our punches, theyll fly back to their mansions in their private jets and laugh all the way to the bank. Reporter an f. D. A. Official also testified during the hearing. Committee members want to know why it takes so long for new drugs to be approved, arguing the hurdles are blocking competition. Pelley vinita nair, thanks very much.

Reporter seniors rodney jackson, kiara jefferson, Latrice Williams and ayo taiwo. I love the roleplaying part of the event. Reporter why . Its like they showed us their everyday life in little scenes. You have your own perception of it, but once you get that other perception, you kind of see how it plays hand in hand and what its like. To have a phone this close to your face while youre trying to talk to somebody, its not your ideal way to handle it. Reporter South Holland police chief Gregory Baker says he became an officer after his friend was gunned down by police. We protect, we serve, but the part thats not mentioned a lot is we care. 99 of the Police Officers out here got into this job because they care about people. Thats what its all about.

Reporter with a conversation to avoid confrontation. Jericka duncan, cbs news, chicago. Pelley and thats the cbs evening news for tonight. For some of you the news continues, for others, check back with us a little bit later for the morning news and of course from cbs this morning. Im scott pelly. This is the cbs overnight news. The suspect, ahmed ramami, is a suspect. His wife is reportedly working with investigators, meanwhile, the search is on for two others who may have started the second pressure bomb without even know it. Jeff pegues has the story. Reporter at 8 30 saturday night, a Pressure Cooker bomb exploded in manhattan. The fbi is searching for these two men who were on 27th street at the same time. Police say the two men removed a bomb from a piece of luggage, putting it on the sidewalk and then walked away leaving the device then taking the suitcase. The bomb never exploded. Nypd chief waters. So if you can help us find them or anybody else can tell us who they are, we would be very interested to speak to them. Reporter investigators are still unsure if Ahmad Khan Rahami was part of a cell or acting on his own, or if there are still other bombs still unaccounted for. According to federal charging documents, rahami bought the ingredients for the bombs on ebay, including chemicals, ball bearings and electric igniters. The f. B. I. Is still trying the figure out where he built the bombs, but two days before the bombings, the documents say a Family Member filmed rahami burying a small black cylindrical object in his backyard. A fuse was lit, there was a loud noise and flames followed by billowing smoke and laughter. Today at a counterterrorism hearing in washington, Homeland SecurityCommittee ChairmanMichael Mccaul held up a copy of rahamis handwritten journal. He talks about god willing the sound of bombs will be heard in the streets, gunshots to your police, death to your oppression. Reporter blood stained with a bullet hole through it, rahami wrote about martyrdom, and his praise of militants suggests he took inspiration from al qaeda as well as isis. Donald trumps private foundation is coming under more scrutiny, already under investigation by the new York State Attorney general over questions about political donations. Now there are charges that trump used donations to pay his legal expenses. In recent years, Donald Trumps foundation has had lawsuits regarding his campaign. Last night, donald trump bragged about using other peoples money in business deals, sort of the way the charity is operated. And without irony, he said he would bring at least one aspect of that to foreign policy. We cant have these people come to the united states, we dont know who they are. We know nohing about them. Donald trump offered two remedies to terror threats, tougher screening of immigrants, and safe zones for refugees. Its called opm, i do it in business all the time. Other peoples money. There is nothing like do things with other peoples money. That is an apt description of his business practices. 30,000 combined he used for portraits of his own face. His charity has been investigated for months. I talked to tax experts who say they never saw anybody do anything like this in the last few years, which is basically use his legal funds to pay off his business practices. Trump has not given to his foundation since 2008, nearly all the money coming from donors. Trumps foundation showed that he wrote a check to fisher house, a veterans Housing Charity to settle a local zoning lawsuit over an oversized flag pole at his maralago club. The money was due after that man scored a hole in one at a trump golf course, in 2010, they paid for this portrait of trump. The campaign claims the washington story was riddled with inaccuracies. But when pence was asked to talk about the inaccuracies, he couldnt come up with a single item. And last year more than 2 million bags were mishandled. Now, delta is using a new tracking system to help keep tabs on luggage. If that is not good enough, there are tracking devices. Kris van cleave reports. We have been trying out these devices that aim to tell you if your luggage is coming to that baggage claim carousel near you, or if its not. The rate of bags lost or damaged is on the declined, but about one in three passengers will have it happen to them. On this day, that passenger was ron mullinex. Ron, that feeling when youre at the carousel and everything stops and youre still a bag sho short. Yeah, youre disappointed but we know it happens. Delta airlines is spending 50 million to make sure it happens less. They are placing the rfid, instead of a bar code which should allow the Realtime Tracking of a suit as as it is loaded onto or off of an airplane. American alerts fliers when their bags are taken off or put on a flight. Alaska air is trying to determine if these are better than the air bar codes that can smudge and wrinkle. Every time they lose a suitcase and cant get it delivered, it costs about 100 to bring it to the hotel, that is an expense they want to avoid. We tested these three luggage tracking devices in this suitcase. It can track your phone, weigh itself and remotely lock. But it is small and we found the location feature to be hit and miss. This provided a list of places where our bag had been complete with a map, working with a smartphone connection. Both devices require a service that consistently located our luggage on a map. It beats the hours alayna connelly spent waiting for her bag. Definitely frustrating and annoying. The devices cost 40 to 80 plus the subscription fees. Deltas new plan will happen in the coming months, the airline believes they will reduce lost luggage by 18 to 20 , which is around the range of 20,000 bags a year.
