Pelley today president obama revealed that the dozens of special operations commandos he ordered into syria are now on the ground and have begun to work with local forces fighting isis, or as he prefers to call the group, isil. Here was the president at the pentagon today. The point is isil lead kearse leaders cannot hide, and our next message to them is simple you are next. Pelley mr. Obama said he is accelerating the war in syria and iraq after isis bombed a russian jetliner, directed the attack in paris and inspired another in san bernardino. Tonight we have a rare look at what u. S. Forces are facing. Charlie dagata linked up with americas kurdish allies. His story begins in iraq. Reporter even when colonel badal bandi told us his forces face isis attacks every day, we of them, until he showed us where three suicide car bombers tried to charge their outpost at dawn. His soldiers shot the drivers dead before they detonated their bomb, but the car bombs remained no more than 50 yards away. [explosion] here on the front line, the bomb squad is a 50caliber gunner. First went up in a plume of smoke. He then opened up on the car in the ditch, the one much closer to us. We watched until he finally made a direct hit. [explosion] the massive explosion blew shrapnel in every direction and filled a bunker with choking dust. That noise is debris from the bomb and wreckage from the car that came crashing down. Everybodys ears were ringing, hours later, we crossed into syria where rebel commander Talal Ali Selo gave us a grim picture of just how many Suicide Missions theyve seen. Can you give me an idea, how many have you had to face in the past month . 42 car and truck bombers, he said, three on motorcycles and four suicide bombers on foot. This week three car bombs killed 28 people. The colonel told us the town had run out of sugar stork get past checkpoints, isis hid the bombs in trucks delivering sugar. You went to the funeral today. What are people there telling you . They want revenge for the dead, he told us, and they want us to make sure this doesnt happen again. The colonel told us although they stopped most attacks, scott, its hard to stop them changing tactics. They never know when theyre going to strike, and they seem to have an unlimited supply of suicide bombers. Pelley Charlie Dagata on the battlefield, thanks. Theres also apparently an unlimited supplier of followers coming from the west. So today the white house is screened. One of the terrorists who killed 14 in california wrote online jihad. Then she got an american visa. Jeff pegues has more. Reporter when Tashfeen Malik applied for a fiancee visa in 2014, she had her name and face checked against terror watch lists, but whether she posted radical views on social media was not checked. Alberto fernandez until recently ran the state Departments Program to counter isis online. Nowadays every company that hires is looking through your social media. Reporter should the government be doing more . This is the crazy thing about this debate. You would think that people who are trying to come to the United States to live in the United States, a privilege that most people dont have, would actually have that scrutiny. Reporter the department of Homeland Security says it began three pilot programs in 2014 to examine whether screening social media was consistent with current laws and privacy protections. Today government officials dismissed allegations Homeland Security secretary jeh johnson delayed the implementation of new rules because of Public Relations concerns,. A review of the policy is under way. Since the attack, some members of congress have been demanding changes to the visa screening system. New york senator charles schumer. And have they checked now Tashfeen Malik a little more, maybe she wouldnt have gotten a visa. Reporter even one of the organizations is not against increased social media scrutiny. Ibrahim cooper is with the council on American Islamic relations. Measures that target only one faith group, only one ethnic group or people from a Certain National origin, that raises concern, and its also counterproductive to our nations security. Reporter last year there were more than 460,000 visas issued. Scott, there are concerns that adding a layer of social media scrutiny could delay the process, hurting tourism and business. Pelley jeff pegues in washington. Jeff, thanks. Today Donald Trumps physician said the republican candidate would be, and this is a quote, the healthiest individual ever elected to the presidency. He called trumps Blood Pressure of 110 65 astonishingly excellent, but even that trumpian hyperbole couldnt help with other numbers today that arent so healthy. Trump trails ted cruz in iowa by ten points. Heres major garrett. Were doing really well. Iowas been amazing. Reporter donald trump is no longer winning in iowa. The Des Moines RegisterBloomberg Politics poll is one of two in the last week to show ted cruz on top. The third poll out today has trump and cruz tied. Faced with adversity, trump is now attacking cruz. I dont think he has the right temperament. I dont think hes got the right judgment. Reporter tough. Mocked cruzs frequent clashes with g. O. P. Leaders, most memorablely when he triggered the 2013 Government Shutdown in a futile attempt to end obamacare. You look at the way hes dealt with the senate, where he goes in there like, frankly like a little bit of a maniac. Youre never going to get things done that way. Reporter cruz considers the shutdown a demonstration of zeal among gop establishmentty aggravated trump supporters, did not argue the point. Instead he posted this throwback video of the movie flash dance, dedicated, cruz said, to maniacs everywhere. Trump and cruzs bat until iowa has come at the expense of former leader ben carson. He told an iowa radio show hes fallen behind as terrorism has become a top campaign issue. Tomorrow nights debate will give carson a chance to turn the tide on foreign policy. Marco rubio, whose november rise in the polls, has suddenly stalled, is also in need of fresh momentum. Scott, rubio is still best positioned as the republican alternative should voters want one, to trump, cruz and carson. In venice but in vegas. Major, thanks very much.

Bergdahl was a taliban prisoner for five years after he walked away from his post in afghanistan. He was swapped last year for five prisoners at guantanamo.

It was three years ago today that a gunman opened fire at Sandy Hook Elementary School in newtown, connecticut, killing 20 first graders and six adults. Vice President Biden tweeted, since that nightmare, an estimated 555 children have been killed by guns in america. It is shameful that congress has not acted.

Reporter when the numbers became names charlotte, daniel. Reporter and the names became face, suddenly they were americas children. 20 first graders gunned down in their classrooms along with their teacher. Its always 12 14.

There are opportunities to intervene to stop that continuum before it leads to tragedy. Reporter together they travel the country teaching others how to respond to those signs. They call it the Say Something campaign. If you see someone at risk, Say Something. That training worked recently in cincinnati when a student reported someone plotting an attack. Reporter the whole thing was stopped and diffused. Oh, yeah. I burst into tears. It was overwhelming. To actually know we potentially saved lives, that means something. Reporter and so does sweeping Gun Legislation they helped nass connecticut two years ago. It expands the been on assault weapons and limits the number of but the campaign has had its setbacks. With the defeat of a bill two years ago that would have closed loopholes in background checks for gun buyers. A lot of people say, if it didnt happen with newtown, when will it happen .

On an average day in america, 31 people are killed with gun homicides, and 58 people shoot themselves with guns. This isnt just a law Public Health problem. Homicides and suicides are the numbertwo and numberthree causes of death in young people and teenagers in america today. Those people arent being killed with viruses. Theyre being killed for the most part by bullets. The gun is, after all mark sheen, a mechanical object that causes injuries, like a car, and car crash deaths in this country have dropped by more than half in 1980 by a Public Health approach with safer highways and safer car design. We can take a Public Health approach to design safer guns and put in other Public Health as well. We need a much more thorough process for background checks. You can undergo a more thorough vetting if you want to adopt a cat from a shelter. If you can reduce the number of guns in america, we can prevent an awful lot of those shootings.
