That they were there and they saw this take place. Is there any evidence to support trumps claim . And holiday rush. Thanksgiving travelers hitting the highways and heading to the airports in droves. The drewing storm that could disrupt the plans of millions of americans, today, tuesday, november 24, 2015. Announcer from nbc news, this is today with matt lawer and sgautry live from studio 1a in rockefeller plaza. And good morning, everyone. Welcome to today on a Tuesday Morning seems like we say this every day, but what a busy morning weve got. Certainly is. And weve got breaking news at top this morning. A russian fighter jet crashed, turkey claiming it shot down that warplane after repeated warnings saying that the plane was violating its airspace. Lets get right to nbcs chief Foreign Correspondent rich engel in istanbul this morning. Richard, what are you hearing about this . Reporter good morning, savannah, turkey says it acted legitimately when a then unidentified aircraft violated its airspace, did not heed warnings. Kremlin, however, is disputing that claim and calls this incident they serious. Russias Defense Ministry says its jet which turned into a fireball when it was shot down this morning was inside syrian airspace, its location confirmed by its instruments. The jets two pilots appear to have ejected bailing out before the plane impacted. Helicopters could be seen searching for the pilots. Russia blamed ground fire which attacked the jet on a mission in syria near the turkish border, but turkey said two of its u. S. Made f16s like these shot down a jet after it illegally entered turkish airspace. A statement from the fishingish president s office claimed the jet was warned ten times over five minutes. Russia has dramatically increased its air strikes in syria it says against isis after a bomb destroyed a russian passenger jet over egypt nearly a month ago. Isis is new in the crosshairs the russia, the u. S. And france, all three air forces targeting the group in syria but with little coordination. A video circulating online which is still yet to be confirmed by nbc news. His body recovered by a rebel group. The rebels claim that he died before hitting the ground. This has major implications. It is the first time in recent memory that a nato country, and turkey is a nato country, shot down a russian plane. Nato has called for an extraordinary meeting today. Dangerous situation, richard engel, thank you. Another story were following, a new bulletin from u. S. Security officials revealing new information about the planning that went into the terror attacks on paris and a warning to local Police Departments here in the u. S. To be mindful of potential copycat attacks. We have complete coverage beginning with nbcs chief Foreign Affairs correspondent andrea mitchell. Andrea, what can you tell us . Good morning, matt, that is right. Overnight top counterterrorism u. S. Officials warned local Law Enforcement around the country about the new details of the paris attacks to help prevent a copycat attack here at home. At the same time, the state department is the alerting u. S. Travelers to be very careful, i especially careful overseas. A new bulletin reportedly issued by the fbi, the Homeland Security department and the National Counterterrorism center warns u. S. Law enforcement to review active shooter scenarios, warning thaek extremists could seek to replicate the effects of the paris attacks using similar weapons and tactics, although on a smaller scale. Sent to more than 18,000 agencies across the country, the document asked them to be on the lookout for suspicious people conducting surveillance on soft targets in the u. S. An bulletin analyzes the reesens paris attacks, acknowledging the terrorists used a cell phone with maps of the concert venue and encrypted apps and rented three cars in belgium before moving to a safe house in paris despite warnings that home grown extremists could seek to immick these strategies plots like parris more likely to happen overseas because of geography and societal factors. Just as some travelers are leaving for europe and other foreign destinations, a second bulletin from the state Department Says they should exercise vigilance when in Public Places use transportation. Be aware of immediate surroundings and avoid large crowds and crowd places. Exercise particular caution this Holiday Season and at holiday festivals or events. The travel alert cites multiple attacks in paris, mali, nigeria and turkey and the bombing of the russian passenger plane, and it says there is a continuing threat from unaffiliated persons planning attacks inspired by major terrorist organizations. In other words, copycats and lone wolves. Homeland security says that there is no evidence of an attack pending here in the u. S. , but officials offer no such assurances for what might happen overseas now that isis has shown can attack in the heart of europe. Matt and savannah. And i yeah, thank you very much. Shaun henry is a former executive assistant director for the fbi. Good morning to you. Good morning, matt. Are these official versions of what americans are thinking anyway . I think thats right. You know, we hear about this fbi bulletin that went out to local Law Enforcement yesterday. It really doesnt say much more than what weve opinion talking about over the last week but its very form a. Its the fbi making sure they are clearly communicating to local Law Enforcement that were looking at people doing reconnaissance, looking at people that are tactically trained and better be training local Law Enforcement for active shooters but a we want to be able to ensure they can respond quickly should there be an incident here domestically. And lest there be any doubt, shawn, they are telling local officials to look out for soft targets, not even military installations and tourists attractions. In paris it was a cafe on a friday night. What we saw in paris really changes the dynamic what have weve seen for terrorist organizations in years gone by. I think whats chrisically important here for local Law Enforcement to know and trying to get out information that there are millions and millions of people who have to be eyes and years. Local Law Enforcement cant cover every cafe, every restaurant and every sporting event. People need to step up and be aware and by putting this report out it really helps to focus the american public. They have been watching the media, and they see what happens in paris, but this going out officially like this really says to americans be aware, be alert. Dont be afraid, but make sure youre advising Law Enforcement if you see anything that could be unusual so that they can be responsive. All right. Shawn henry, thank you very much. There was also the warning, of course, to the woorldwide travelers from this country as well. President obama meantime facing increased pressure to up the u. S. Campaign against isis, and that is on full display the white house today. President obama will meet with french president francois hollande. Nbc National CorrespondentPeter Alexander is at white house covering the meeting. Peter, good morning. What do you expect. Reporter good morning, president s obama and hollande will stand in solidarity here this morning, but president obama has largely resisted calls that he change or even significantly ramp up his strategy against isis. Today the french are likely to push for a stronger u. S. Military commitment here. That may mean more special forces on the ground to help identify isis targets, greater intel gathering and lesser stricter rules of engagement which could mean lesser casualties in syria. This is the same did a that president hoped announced france is at war with isis the president said it was a setback. Despite pressure and a lot of it from former allies and even former advisers to be more aggressive, the white house officials insist the u. S. Is more than pulling its own weight. The french also want the u. S. To back efforts to bring russia into what they call a single Broad Coalition to fight terrorists. Thats not likely to happen. Hollande wasnt even stay the night before he head to moscow for a similar motoring with vladimir putin. Thanks, lets turn to mark halperin, managing editor of bloomberg politics. Good morning. Here we see hollande doing some version of shuttle diplomacy meeting with the president here and going on to meet with president putin. What is he trying to put together here, sand he likely to be successful . He wants more intelligence sharing and wants the russians to stop focusing on fighting the rebels and fighting isis and there wants there to be kind of a greater sense of coalition, but theres not much difference between u. S. And france as some people would think. The u. S. Would like russia involved on good terms and would like the diplomatic tract to work. Thats the most important thing and why the president is trying to be low key. Wants diplomacy to work to get assad out of power and turn to isis full force. If hollande asks the president for more robust ground presence, special forces, special operations troops and the president says no, here comes hollande with the attacks in paris fresh in everyones mind. Hes got emotion and timing on his side. What arent optics going to look like if he walks away without that . It would look horrible but talking to a Senior Administration official i dont think the United States think the france will ask for that, special operations but not a large number of ground troops. Not capability unless the u. S. Is willing to lead a capability the french know it cant happen and president obama does not want that. Iraq is always in his mind as an example of how america shouldnt operate in that region. Talked about substance and lets talk about the style because the president s remarks after paris were widely panned even by some of his allies because of the tone, because felt he came across at defensive and more passionate about his political critics than what had happened in france. Now he has this press Conference Today with the french president by his side. Is it a chance for kind of a rhetorical doover and does the white house even feel thats necessary . The president feels like he cannot set a bad example. Again, the iraq example is in his mind. Hes not a guy who wants to pound the table and says were going to get these guys. Well help them down across the world. He thinks its count productive. He thinks its low key. He doesnt want the United States to be the enemy of the region. Theresin presentation bill clinton uses, its better to be wrong and strong and right than weak and the president feels hes right. Doesnt fear being perceived as weak if he feels hes making the right decision. What are the folks saying about the criticism, not from the republicans running for president , but from democrats like leon panetta and Dianne Feinstein and hillary clinton. Go back to forget what we say, watch what we do. The diplomacy, the sharing of intelligence is more important than style criticism of what the president does. The president believes that if he says things that are loud and violent and aggressive its counterproductive and he doesnt want this pop theial campaign to be dominated by what he considers dangerous demagoguery that will hurt america around the world. Agreed it will feed right into isis hands. Republican president ial frontrunner donald trump is standing by his claim that he saw muslims in new jersey cheering the World Trade Center attacks. Nbc ehallie jackson has the latest on that story. Hallie, what do you have. Reporter this morning donald trump is doubling down on those comments, some of his most controversial ones yet, even in the face of fact checks. If you thought trump would back down, think again. Donald trump delivers a tirade overnight in his own defense. I saw people getting together and in fairly large numbers celebrating as the World Trade Center was coming down. I saw them on television, and i read about it on the internet. Reporter his claim, that thousands of muslims in new jersey cheered 9 11 has been denounced and widely discredited by multiple independent fact checkers. Trump standing by it. I start getting phone calls in my office by the hundreds that they were there and they saw this take place. Reporter republican frontrunner not apologizing but ben carson is, backtracking after first saying he also saw american muslims celebrating 9 11. I think that was an inappropriate response. Did you see that happening on 9 11 . I saw the film of it, yes. In new jersey . Yes. Reporter now though carsons Campaign Says he does not stand by those statement and was thinking instead of celebrations in the middle east, not new jersey. I did see the film. I dont know where they were, but i did see a film of muslims celebrating. List distancing himself from trump marco rubio. At what the point do you feel like you and the rest of your competitors have to call him out on that . Its not true and plenty of fact checks. If all i did was respond to everything donald trump said that isnt true i wouldnt be able to run my campaign. Reporter rubio, meanwhile, will begin airing his first broadcast ad in key early states. Heres an exclusive first look t. Focuses on his father and his family story, a way to introduce himself to voters in iowa and New Hampshire as rubio hopes to take the top spot in the polls from trump. A new one out this morning, matt and savannah, shows trump still leading in iowa, though ted cruz is coming on strong. Guys. Hally jackson, thank you. Meantime, the thanksgiving travel rush heating up today. Millions. Americans will hit the roads and head to the airport so what do you need to know if youre heading out. Well be your travel headquarters over the next few days, and well start with mr. Roker. What are you watching is. Seventh year in a row an increase in travel more than 50 miles from home, so people are in a mood to travel. Lets show you what were talking about. First of all, as far as that travel is concerned, 46. 9 Million People will be traveling this year and 89 will be driving and it will be kind of interesting. Were watching three trouble spots over thanksgiving. Especially thanksgiving day. Chicago, denver, dallas. Lets start off in denver as we go to the maps and show you exactly what were talking about. First lets look at shim ohair airport. Look at this, already, at 6 00 a. M. Central time, 7 00 a. M. Eastern time, it is packed and its just going to get worse. This is tuesday. Can you imagine what this is going to look like tomorrow. Well, heres what were looking at. Denver is going to be our first hot spot that were talking about. Light snow, freezing drizzle by thursday. Delays in the air due to visibility and dangerous road conditions. Now were going to move down to dallas where heavy rain. Another three inches. They will have the rainiest year ever. Rain with thunderstorms. Delays between these storms and on the road gusty wind and heavy rain. Going to be a problem there, and we head up to chicago. Another big hub. Rain with a flood threat. Because of the snow on the ground, warming temperatures and heavy rain. They will have problems and delays in the air due to visibility and well have roads that are slick with some flooding, guys, so, again, big problems going to continue right on through thanksgiving day. The good news is friday into the weekend looking much better. Thats whats going on. Were going to get a good morning. Im meteorologist bill henley. Clouds are here and it is cold this morning. But sunshine will break through this afternoon. The temperatures climb into the middle to upper 40s, near 50 degrees later today. And into the 50s tomorrow with bright sunshine, a high of 53. The real warmup comes for thanksgiving day and friday, both days will see afternoon temperatures in the 60s. Showers swing through saturday, turning colder sunday and monday. Have a great day. And thats your latest weather. Savannah . All right, al. Thank you. Theres some new reaction this morning over the concussion suffered by st. Louis rams quarterback case keenum that happened in the nfl came on sunday and natalie has been following that this week. Whats going on . Rams head coach jeff fisher address ed the issue yesterday. Will nfl says their concussion protocol wasnt followed sunday and they want to know why. The league is now investigating why both Team Trainers and independent injury spotters called atcs allowed rams quarterback case keepium to continue playing after this brutal hit. Oh, boy. You can see him go down and hit the back of the head on the turf. He was only diagnosed with a concussion after the game. I didnt see it from my vantage point. Rams coach jeff fisher monday promised to investigate how the system broke down but would not blame the spotters or his trainers. Our head train er did go on the field and he got out there and he spoke to case and he questioned case and case said he felt okay. Sports pundits on espn were nowhere near as kind. This failed on every single level. It was actually disgraceful. I watched it live. It was horrifying to watch. It really was. The nfl has had a concussion protocol in place since late 2011, even expanding the role of the interpent spotters beginning this season, giving them the power to stop the game if there is clear visual evidence of the player displaying obvious signs of disorientation or is clearly unstable and is attempting to remain in the game and not be attended to by the clubs medical staff. The 27yearold struggled to get up, even flopping back down after a teammate tried to pull him up immediately. To see a hit like that and to see him get up and be so obviously in distress, how anybody could have left him in the game was just, you know, its just awful. Fisher said keenum feels much bert and will play this weekend if the quarterback passes the remaining steps in the leagues concussion protocol. The Players U
