his e-mails are being read by the chinese and russian governments and he writes his e- mails with that in mind. his comments suggest that confidence in security has been shaken at the highest levels after relentless hacking of federal computers. do you think the chinese and/or the russians are reading your e- mails? >> well, we know that the-- t fortunately, we're living in a world where a number of countries, the chinese and russians included, consistently have been engaged in cyber attacks against american interests, against the american government, and it's an issue that we recently raised very, very strongly in our dialogue with the chinese. the answer is, it is very likely. it is not without-- outside the realm of possibility and we know they have attacked a number of american interests over the course of the last days. >> pelley: it's very likely that your e-mails are being read?

>> it's very possible. there's no way for me-- and i certainly write things with that awareness. >> pelley: with all of the attacks that have come, apparently, from china on the u.s. government, there is a sense that the united states is unable to defend itself in the cyber world. how much concern should we have? >> well, the cyber world, as you know, scott, is a very complicated and fast-moving world. we are deeply involved in bghting back against this on a daily basis but right now it's pretty-- it's pretty much the wild west so to speak. >> pelley: and it is a gunfight. in july, the unclassified e-mail of the nation's top military officers, the joint chiefs of staff, was penetrated. 22 million federal workers lost their private information when the federal office of personnel management was cleaned out, probably by china. and white house unclassified e- mail was pilfered in a suspected russian hack. a little later, we'll hear

secretary kerry's honest assessment of america's war against isis, and why he believes the iran nuclear deal is essential to peace. there is also breaking news tonight about the e-mails of former secretary of state hillary clinton. she's turning over her private e-mail server to the justice deparment, and nancy cordes has the latest on this. nancy. >> reporter: scott, clinton has directed her aides to hand over both her server and a thumb drive containing her e-mails to the department of justice. it's a victory for republicans in congress who have been pushing for clinton to turn her server over for months, ever since she revealed she turned over what she considered work e-mails and athleted the rest. the move comes as clinton's e-mail setup is getting new scrutiny from both the f.b.i. and the intelligence community. just today, the intelligence community's inspector general told congress that two of clinton's e-mails out of the 40 he reviewed should have been marked classified at the time, and not just as confidential,

but as top secret. that's one of the highest levels of classification. the f.b.i., as we've reported, has contacted an i.t. company in denver that helped to set up clinton's server in her home in chappaqua, new york, and the f.b.i. also examined where the thumb drive was secured by clinton's personal lawyer. now, that thumb drive is going to be held by the f.b.i. itself. no one, including clinton herself, is under criminal investigation right now, and the state department is actually pushing back at the notion that the information in these e-mails should have been considered classified at all. so there's a dispute with the intelligence community there, and regardless, scott, clinton says she plans to cooperate with this ongoing inquiry and will answer any questions that come her way. >> pelley: nancy cordes, thanks. a new poll shows donald trump holding the lead among republicans in iowa. 25 weeks before the iowans go to the caucuses. next are walker, rubio, and carson.

they're followed by cruz, fiorina, bush and kasich. trump hit the campaign trail in the midwest, and major garrett is with him. >> reporter: the sign said it all. a crowd of nearly 2,500 lined up in saginaw, michigan for donald trump's first campaign appearance since last week's debate. oh, i think the republican party is going to do really well. >> you said a moment ago you're going to be great on jobs. jeb bush has qawntified how much he's going to have economic growth. >> jeb bush will not be able to negotiate against china. jeb bush will not be able to negotiate against mexico. jeb bush with mexico said people come in, they come in, it's an act of love, okay. it's not an act of love. we need a wall. >> reporter: despite leading in the polls, trumped received mixed reviews for his debate performance. 55% of iowa republicans said they were less comfortable with trump after watching the debate.

in new hampshire, 41% of republicans said they supported trump's ideas but did not think he had the temperament to be president. >> thank you, guys. >> reporter: former florida governor jeb bush argues he does have that temperament. in a speech tonight at the reagan presidential library, bush will lay out his foreign policy doctrine. according to excerpts bush will blame democratic frontrunner hillary clinton for the rise of isis in iraq saying: the clinton >> reporter: the clinton campaign accused bush of rewriting history in iraq, as for trump, he continues to flirt with the idea of a third party campaign if he doesn't secure the republican nomination. but, scott, few in this capacity crowd, which began gathering four hours ago, appear to mind. >> pelley: major garrett on the campaign trail. major, thanks. >> reporter: in ferguson, missouri, people were arrested overnight in the protest marking

the anniversary of the fatal police shooting of michael brown. in the protest sunday, officers shot tyrone harris, and in a video they released today, harris is seen carrying a gun and running toward the police. flash floodcould force force some to higher ground in colorado tonight. look at the downpours yesterday that washed away these cars in colorado springs. nobody was hurt. carl parker of the weather channel is tracking these storms for us tonight. carl, what's next? >> scott, this flood was caused not only by heavy rain but also y a fire which occurred more than three years ago in this location. and there's the video of this wall of muddy water coming down across manitou springs, a sleepy town of about 5,000. it swept away cars, and damaged buildings. the waldo canyon fire burning over 18,000 acres in june of 2012 left a very large burned inea. that burn scar continues to lack vegetation today so when heavy rain falls on that area there is

really nothing to absorb all that water. that's exactly what happened yesterday. rain began to come down around 11:15 mountain time, got much, much heavier by the middle of the day, and then it quickly moved out, but the damage had been done. all that heavy rain running down through those mountains causing that flash flood. we are still seeing some wet weather in the area today. there's a general area of moisture coming around high pressure centered in the southern plains. that high is going to expand over the next couple of days, and that will slightly bring down the chances of heavy rain there in colorado. thott, back to you. >> pelley: carl parker of the weather channel. thanks very much. 60-mile-an-hour winds blew a huge dust storm into phoenix today. it darkened the sky before an inch of rain fell in just 30 minutes. flights were diverted and thousands lost power. the pentagon's first attempt to train syrian rebels to fight isis was what one official called an "abject failure." most of the 54 fighters are

dead, captured or missing. another 600, who passed the u.s. vetting process, have dropped out. holly williams found out one reason why. >> reporter: america's hopes of defeating isis in syria depend on fighters like abu suleyman and abu yazen, battle-hardened 22-year-olds, both too frightened to show their faces because their parents still live under isis rule. in april, along with other fighters from their brigade of so-called moderate rebels, they signed up for u.s.-funded training, but after completing the program and receiving their first $500 in pay, they quit. "we felt betrayed," said abu suleyman. "about halfway through, we realized the trainers only wanted us to fight against isis and not the syrian regime." both men told us they'd risked

their lives battling isis. but like many rebels, they believe the bigger enemy is the syrian government, which continues to bomb its own people. the 54 who completed the training and returned to the war p.ne were quickly attacked by an al qaeda-linked group. captain ammar al wawi is an officer in the division to which the 54 belonged and told us five were killed and 13 captured. what went wrong? "they had no protection from the air, and they were surrounded by terrorists," he told us. "they should have waited until they at least had 200 men so they could defend themselves." captain al wawi told us the u.s.-funded training is progressing so slowly that, scott, at this rate, building a 15,000-strong army will take more than 30 years.

>> pelley: holly williams reporting for us tonight from istanbul. holly, thank you. oud we spoke to secretary of state kerry about the troubled fight against isis, which the u.s. government calls isil. >> this is tough. and, obviously, it didn't go well. i think it's admirable that they've admitted that it wasn't what they wanted it to be. there are-- you know, the complexity of that battlefield cannot be overstated. so i think the numbers of different people, who's turning co who, and it underscores the complicated fight against da'ish, isil. >> pelley: is the war against isil worth fighting? >> absolutely. q pelley: then why isn't it worth fighting decisively? >> i think the question is who is going to make that decisive difference. the president has decided, and i think appropriately, that american forces are not the ones best suited to be able to take ouat fight at the moment and it is not in the best interest of our country. >> pelley: secretary kerry is campaigning for the nuclear deal

that he struck with the iranian foreign minister. iran agreed to dismantle most of its nuclear program in return for the lifting of crippling otonomic sanctions. >> we're not asking anybody to stust iran. iran doesn't trust us. we don't yet trust them. and who knows what the future brings. so this agreement is built on real-time verification now. iran, in order to get any sanctions relief, has to reduce its program very significantly. it has to destroy its core reactor at its plutonium heavy water reactor. it has to take all of its enrichment out of other facilities. it has to hold its program back to 300 kilograms of stockpile of low-enriched material for 15 years. ig are convinced, through our intelligence community and through our energy department, which is responsible for nuclear weaponry, that we will know what iran is doing.

>> pelley: one of the key criticisms of the agreement is a provision that allows the possibility of up to 24 days before international inspectors would be allowed in to an iranian undeclared nuclear site. let me show you what prime minister benjamin netanyahu told us about that. >> sure. >> in fact, you have to give them not 24 hours notice inspecting the suspect site, but 24 days' notice. now, can you imagine your drug dealer and somebody tells you i want to inspect your premises. that's a lot of time, 24 days, to flush a lot of meth down the toilet. >> pelley: your reaction? al well, my reaction is, with all due respect, nuclear material is not like drugs. you can't flush it down the toilet. you can't get rid of nuclear material that way. it lasts for hundreds, thousands of years. >> pelley: they cannot build a nuclear weapon over the next 10 years in this agreement. >> no, they cannot, not possibly

under this agreement. >> pelley: secretary of state john kerry, thank you very much for being with us. >> thank you. to pelley: in a surprise move today, china lowered the value of its currency by 2% to try to boost exports. concern about a weakening chinese economy led to a sharp drop in u.s. stocks. the dow lost more than 200 points, the s&p 500 was down 20. oil prices then fell to the lowest price in six years, just over $43 a barrel. investigators reveal the cause of the deadly crash that injured facy morgan. firefighters face manmade obstacles in the sky. and a rider hits more than a bump in the road when the cbs evening news continues. continues. three-quarters of what it takes to replace it.

and killed another comedian last year. a wal-mart truck driver who hadn't slept in 28 hours crashed into their van. r:re's kris van cleave. >> reporter: this n.t.s.b. animation shows the speeding wal-mart semi did not begin braking until it was just 200 feet from the limo van carrying comedian tracy morgan. truck driver kevin roper had driven more than 800 miles overnight from his georgia home to work. he had been up for more than 28 hours and was approaching his max duty time of 14 hours on the job. dennis collins is an n.t.s.b. accident investigator. >> this crash demonstrates the potential consequences of even one poor decision regarding fatigue. >> reporter: roper had worked for wal-mart for just 15 weeks but his driving had already hanerated nine automated warnings from the truck's onboard computer. he's now facing criminal farges. the n.t.s.b. has now renewed its call for mandated fatigue monitoring and management programs.
