post, by a telephone call that was made, by investigators mining computer data. today, in our investigation, we don't have any of that uncovered. i wish we did. >> reporter: investigators have run down more than 1,000 leads, and the f.b.i. is putting up billboards in the las vegas area asking for more information. one thing that is emerging: the attack cardiovascula could have. law enforcement sources say stephen paddock's car, which was found by a canine unit inside the mandalay bay hotel parking garage was loaded with at least 1,000 rounds of ammunition in a suitcase and the explosive tannerite in a duffle bag. investigators are examining whether the car was part of paddock's escape plan. paddock's cache of weapons included variants of ak-47s and ar-15s. sources say the entire cost of his arsenal

>> reporter: currently, there's a criminal st tatrorismt domestic. former federal prosecutor mary mccord thinks in an era of mass casualties, it's time that changed. >> violent extremism isn't limited to islamist extremism or extremism that's done on behalf of or at the direction of a foreign terrorist organization. >> reporter: with no specific penalties on the books for domestic terrorism, mass killers like timothy mcveigh face charges of using a weapon of mass destruction, or dylann roof, who faced murder and weapons charges. but the label "domestic terrorism" makes the motive clear, says mccord, now at georgetown law, in a way that sharpens our response. >> it shows the significance of this type of a crime, and why it's important for it to be looked at and treated for what it is, which is terrorism. it's a crime done for the very purpose of terrorizing people.

terror law would also mean inved the creation of deeper, wider databases to keep track of mass violence. , of course, there is a potential problem: labeling domestic hate groups as terrests, like al qaeda or isis, raises constitutional questions. >> that starts to get very close to the line of potentially infringing on free speech, freedom to associate and express one's views. however abhorrent they may be to others in the population. >> reporter: during the obama administration, the justice department considered creating a domestic terrorism statute. we asked the trump d.o.j. if it's continuing the work. a spokesman declined comment. >> mason: jim axelrod. thanks, jim. a new storm is on the way. tropical storm nate is blamed for deaths in nicaragua and honduras. it could hilt the gulf coast as a hurricane over the weekend. a hurricane

expected when nate hits. >> i know that you can see now . >> reporter: mayor mitch laundrieu: can you guarantee the people of new orleans that that pumping system will work as it should? >> as a matter of fact, i can. we have plenty enough power and plenty enough pumping capacity to handle those potential rain events. >> reporter: as nate bears down on the gulf coast, power crews are prepping for outages. still, kathy adams says she survived katrina. she'll survive this, too. so there's giving up for you. >> no giving up. after katrina, i wanted to come back home. but now this is what i'm facing again. so you can't run. >> reporter: city officials are just as concerned about wind as they are rain. and if the power grid is knocked out, that could make this pumping system far more vulnerable. anthony. >> mason: michelle miller with the preparations in new orleans. thanks. the body of a fourth u.s. service member was recovered today in the african nation of

changed the obaarulesl. what did it do? >> reporter: well, obamacare requires that employer-provided health insurance cover birth control with a few exceptions. today, the trump administration changed those guidelines and will allow employers and insurers to opt out of that mandate based on their own religious and moral convictions. the rule change full fills a campaign promise by president trump. and the administration estimates that 120,000 women may lose access to free contraceptives because of it. but some women's rights organizations say that number is actually far higher and warn that this could lead to a jump in unintend pregnancies. anthony. >> mason: margaret brennan at the white house. the white house today was talking up a drop in the unemployment rate. it fell .2 of a point last month to a 16-year low of 4.2%. the labor department blamed the loz of

harvey and irma. a group of activists behind the first treat tow ban all nuclear arms was awarded the nobel peace prize today. icahn, the international campaign to abolish nuclear weapons, was formed 10 years ago. the treaty was adopted by 122 countries, but nuclear powers including the u.s., russia, britain, france, and china, boycotted the vote, as did north korea. the nobel committee said the coalition is receiving the award for its work to draw attention to the catastrophic humanitarian consequences of any use of nuclear weapons. but nato secretary-general said the treaty does not move us closer to the goal of a world without nuclear weapons. in fact, it risks undermining the progress we've made over the years in disarmament and nonproliferation. democrats ran today from one of their big donors, movie mogul harvey weinstein, after allegations he s

year. >> i may be ate but i've got nothing for you today. which is why i was so struck by "the onion" published this week. it may be a satirical newspaper, but this article was a serious gut punch. the headline read, "no way to prevent this," says only nation where this regularly happens. there's a phony quote from a made-up person that said, "this was a terrible tragedy, but sometimes these things just happen, and there's nothing anyone can do to stop them." it seemed topical, until i realized, it's the same article they've published after nearly every shooting since 2014. they change the town and the body count, but that's about it. let's face it-- our indignation has taken on a hollow sameness. we say we want to wash away this epidemic, but all we do is pray, mourn, and repeat. we're on a treadmill, and it's killing us.
