down. >> reporter: soon after police say 24-year-old lakeisha halloway pulled into a casino parking lot and told the valet to call 911. >> it looked like she wasn't even trying to stop the car. she had both of her hands on the wheel and was looking straightforward. there were men running after her trying to stop the vehicle, and >> good morning, everybody. >> reporter: clark county sheriff joe lamb bardo doesn't think this was an act of terror but still can't rule it out. >> as far as terrorism, we don't know what the intent was behind it, and we don't know enough of her background to make that determination. we have not had the time or the luxury to get through all those investigative leads yet. >> reporter: lombardo says hollande came to las vegas from oregon about three weeks ago and had listen living in her car with her child, who was also in her vehicle as she ran people down. >> she did not demonstrate signs of being under the influence of alcohol, but we had a drug recognition

expected here on the las vegas strip, maurice, all 35 of the injured were visitors coming from several states as well as canada and mexico. in las vegas tonight. in the presidential campaign, the democratic front-runner has at times seemed to be looking ahead to the general election, taking on republicans like donald trump. hillary clinton has a big lead in the national polls, but the races are much tighter in early voting states. here's julianna goldman. >> i think that's especially appropriate here in iowa. >> reporter: with less than two months to go before the first voting contest, victories are not guaranteed for hillary clinton. according to the latest cbs battleground polls, vermont senator bernie sanders is just five points behind clinton in iowa, and in new hampshire, he's beating her by 14 points. >> if we can win in iowa. if we can win in new hampshire, i think we're on our way to a national victory and one of the great political upsets in the modern history of america. >> reporter: on cbs thursday morning, sanders said he's not seeding any ground, but he continued to accuse the democratic national committee of party's front-runner ad any continued fallout of last week's breech of clinton campaign voter data. >> i believe the action of the dnc to basically shut us off from all of the information that we have put into that base, the lifeblood of our campaign, was totally inappropriate. >> oh, my goodness. >> reporter: one staffer was fired and two others have been suspended pending an investigation into whether the sanders' team has stolen any of the clinton campaign data. clinton is still the favorite to win the nomination, but a loss in iowa or new hampshire could draw out the process, especially because sanders is sitting on a campaign war chest fueled by grassroots donors, and, maurice, that means less time for clinton to position herself for the general election. >> dubois: it certainly does. julianna goldman in washington tonight.

christie has noticed a tidal shift in anxiety. 75% of his questions now are about terrorism, triple what they once were. >> as politicians we need to be responding to that fear. >> reporter: we rode on the christie bus and asked if fear can get the best of people? >> i don't think that we should be afraid of people because of what religion they practice. >> reporter: or how they look? >> of course. that goes hand in hand. what you need to be fearful of is not having enough intelligence to know the difference between a jihadist and a peaceful muslim. >> reporter: how do you do that? >> you first of all ramp back up the n.s.a. program, which never should have been taken down. you give real support to the f.b.i. >> reporter: and what would christie do to recruit more arab and nato allies in the fight >> we have to say to them, this is a fight all of us need to take on together. what skin are you going to have in this game? >> what if they say, not near as much as you want or you demand? >> well, you know what, that's when i become my charming and persuasive self, major, and that's what we do. >> reporter: christie is still running fourth but he's doubled his support in a month. yet he couldn't even submit a full secretary of state of delegates for the iowa primary. >> i'm not worried about that. if we win in ohio, we'll get all the delegates anyway. >> reporter: christie has had to learn patience as for months his campaign teetered on the edge of irrelevancy while distancing himself from a scandal back home. >> listen, the stuff that happened in new jersey, when you take that level of abuse and then you come tournament other side of it fine, you're a much better office holder. christie's republican rivals shrank by one when lindsey graham dropped out. >>

"he would go on operations and kill people," she said, "and then come home and force me to be with him." musa was rescued by the cameroon military, but the worst of her ordeal was finding out she was pregnant by her rapist. she told us, "i am not enjoying that i have a baby from a boko haram man." but she is resigned and there are moments of tenderness. her story is not unusual. boko haram has captured hundreds of girls, the most infamous the over 200 chibok school girls kidnapped more than 18 months ago. musa never saw the chibok girls but often heard the fighters speak of them. like many of the other girls marry the militants. and in a double injustice, many are now stigmatized by their community, girls like musa are regarded as spoiled goods, the baby a very public reminder of a cruel and unfair shame. debora patta, cbs news, minawao, cameroon. >> dubois: a.a.a. said today that for the first time since 2009 the average price nationwide is below $2 a gallon, about 42 cents cheaper than a year ago. a report out today points to a growing danger on the roads, drowsy drivers. those leaving the night shift could be an accident waiting to happen. here's anna werner. >> reporter: this man just came off a night shift. watch the video on the left as he veers all over the road. nearly half the night shift dr. charles czeisler worked on the study. >> they were crossing over the middle line. they were having trouble staying in their lane. more than 40% of the drives had to be terminated because it was judged to be unsafe. >> reporter: more than half the workers tested said they nodded off behind the wheel at least once a week on their way home, and they did no better in the test. >> they knew they were being watched, yet even in that context they couldn't stay awake while they were driving in a simulation of their commute home from work. >> reporter: dallas-area convenience store manager shariq khan starts work at 11:00 p.m. and works through the night. >> sometimes when i get off of my job, when i drive back home, i feel like i'm falling asleep. >> reporter: he believes the lack of sleep led to him having a couple minor accidents. researchers suggest night shift workers like khan skip driving and find another way home, but his area lacks public transportation. >> there's no alternative. service there. and i can't afford to have a taxi every day. >> reporter: researchers say night shift workers are fighting their own natural sleep patterns and they can't sleep as well during the day no matter how much they try. they lose about two hours of sleep a day, and maurice, after a few days, they've lost the equivalent of a whole night's sleep. >> dubois: okay. anna werner, thank you. from victory to defeat in about two minutes. the story behind the miss universe mix-up.
