recruits members across the globe, but we never had such an inside look at how that is to how isis operatesnd as a quasi-government. that tells us how isis sees itself and sees as the most important components. that's brand new to us. it's thanks to the new incredible reporting in "the washington post" today. joining us is greg miller, from "the washington post." he co-authored this article. and mr. miller, congratulations on this reporting. it was really eye opening. thanks for being here tonight. >> thanks for having me, rachel. >> what struck me as most surprising was the degree to which isis privileges, the actual people who do the video production, who do the propaganda for them within their own organization giving them power, status, money, what struck you as most surprising based on sort of how you went into this based on what you learned? >> i think the extent to which how pervasive it and also as you say how tightly sort of choreographed the public events are in the caliphate. it's a public beheading that's a punishment, internal punishment in which the camera crews show up with cu

isis defector. he was part of their state security apparatus which is responsible for training foreign operatives. he said there were a lot of french nationals coming into raqqah joining isis. i said where do they go? he said this some are back in france. there is absolutely a cross penetration. the statistic is something like 250 returnees and that is out of a collective number of 1900 french nationals that are in a state of flux having joined isis been killed in syria or iraq or trying to make their way back across the border. this leads me to believe this is more isis than al qaeda. >> agreed? >> absolutely. when you look at the sophistication of the attack, the multiple suicide vests going off within a close period of each other. there was a high level of training and they were able to pull it together in france and the numbers we are talking about, the government is guessing at. if they say it's 250 you can assume it's higher than that. >> you said these are soft targets. if you go into the stadium you go through security. then what of the stadium? >> this was the symbolic target. the stadium

and according to officials, they're looking at the possibility that isis operatives or sympathizers mayording to one official we talked to, asked directly if this was based on what isis had said earlier or suppositions or whether it was intel and the official indicated that there is some intel that at least indicates that isis may have somehow been involved. no direct evidence, but that's why the investigation is under way. now, according to one official, investigators are looking at the possibility that ground crews at the airport at sharm el sheikh, baggage handlers, food handlers and the like, may have been involved. if indeed it was a bomb, in planting the device on the airplane. and reason they're looking so hard at those ground crews, because immediately after the plane went down over the sinai, and the passenger manifest was available to intel and counterterrorism officials worldwide, they looked at all the names and scrubbed them. put them through all the filters and systems and the names of the crew members as well, and they could find no indication, according to one official,

the official said the investigation is focused on the possibility that isis operatives or sympathizers were directly involved in the bombing. shortly after the crash, isis claimed it had downed the claim, but egypt's president at the time had dismissed it. u.s. defense officials earlier this week told nbc news, a heat flash was detected over the desert at the exact time of the crash. but the infrared satellite did not detect a trail. so that ruled out a missile strike. just a couple of hours ago, john kirby said, we are in no position right now to rule anything in or out. >> because somebody came out and said they thought it could have been an explosive device -- >> not somebody, the british government is on record. >> everybody just wants to jump to that conclusion and i'm not going to do it. but the investigators are still at it. we got to give them the time and space to do their job. that's the responsible thing to do here. in the meantime, it's also the responsible thing for the united states government to tell its workers, don't go to the sinai right now. >> within minutes of john

officials have said that they tracked chatter between isis operatives boasting about taking down the plane shortly after the crash. aaron? >> 15 before the hour now. we turn to the heels of the terrorist attack in paris and more than a dozen republican governors saying syrian refugees should not be allowed in the u.s. president obama wants to accept 10,000 refugees over the next year. so why do opponents say helping syrians could make the u.s. vulnerable? tracie potts is digging into that for us on capitol hill. good morning. >> they say it is very easy for isis to slip into this country disguised as a refugee. remember, it was a syrian passport found at one of the paris bombers which several are pointing out. 18 governors saying no to syrian refugees. 15 flat out reject. three asking the federal government not to send them to their states. can they actually do that? the state department says they got lawyers looking into whether or not these states actually have the right to reject these refugees from a federal government program. president obama said it is against our values not to
