The centers for Disease Control now investigating as officials reveal samples were shipped under less rigorous conditions since it was believed the bacteria was dead. Nbc news reporting fed ex transported the samples. Fed ex tells cnn theyre working with officials to gather information. No known risk to the general public and no suspected or confirmed cases of anthrax infection. This comes less than a year after a similar mishap at the centers for Disease Control. They shipped what they thought was dead agent so several locations and it was not. It was live anthrax. Alisyn. All right. They have got to figure that one out. Barbara, thanks so much for that update. We have some breaking news this morning. The new York City Police department and other Law Enforcement agencies across the country ramping up surveillance on suspected isis sympathizers in the u. S. Cnns justice reporter evan perez is here with all the developing details. What do we know evan . Good morning, alisyn. There are hundreds of suspected isis supporters in america. And the fbi says it cant keep an eye on all of them. Now Police Departments including here in new york are stepping in to increase their surveillance of people who are potential isis terrorists. Law enforcement officials tell cnn the fbi surveillance squads are tapped out, not enough of them to track people using social media and talking to isis members overseas. The fear is that those people could be plotting an attack here. We asked the fbi director james comey about this yesterday. It is an incredibly difficult task that we are enlisting all of our state and local and federal partners in. And were working on it every single day. But i cant stand here with any high confidence when i confront a world thatsin creasingly dark to me and tell you ive got it all covered. Now, the change in strategy is part of the fallout from the foiled terrorist attack a few weeks ago in garland, texas. Two gunmen inspired by isis tried to attack a Prophet Muhammad cartoon contest. Now, they were killed by police but Law Enforcement officials tell me that one of the gunmen elton simpson, was under fbi surveillance. But it wasnt 24 7. Fbi agents lost track of him for a few days. But the fbi had no idea that he was on his way to texas to carry out his attack chris. And then evan, they got really close on the timing. They wound up alerting local authorities but not in time. Now we see this change. Is this going to be what bridges the gap . Lets bring in a Cnn National Security analyst who worked in the department of homeland security. Lets give the plus minus on this. Why is this good news. Well because the fbi is acknowledging what it has sort of whats obvious in this world in the post 9 11 world and what isis looks like. Which is membership in isis now is anyone who says theyre a member. Its too many people. So they need to work with local and state officials to figure out whats going on. The bad news is of course theres too many people. And this notion of membership in terrorist organizations, a notion we used to think of being quite formal and we could figure out who these guys are now is just a movement. Its very hard to track a movement. And every person thats online figuring out whether they want to be a member of isis or not. So its good news bad news at this stage. The proof of the bad news is what we saw in garland texas. The fbi got information to local authorities but not quickly enough chlgt you wound up having those two fools trying to do something terrible and they got stopped. But we were probably lucky there. Does that prove this isnt the fix . I dont think so. Garland is such a weird example in so many ways because it was sort of a bullseye. In fact i sort of look at garland as bad news. How would we not have seen this coming given that this organization was sort of you know we all knew that the garland event was going to be a target. So the fact they couldnt stop it even beforehand i think suggests how limited resources are for preventing attacks like this. And we dont normally get instances like garland. Most instances are sort of random day and potential isis member will attack. So weve got to engage local and state officials, Community Members and of course communities of interest who might see radicalization in their own communities. Thats the only way youre really going to be able to target this. The Government Resources are limited and maybe not the most effective for the kind of recruitment isis is doing. Two other quick takes on security strategies. First, Something Else we saw in garland, texas. Allowing not to show the picture or image of muhammad the media doesnt do it we dont encourage it here. Is that caving in or being cautious . No i dont think its either. I mean in some ways chris, i just think its sort of respect for any religion in the same way that you dont sort of just randomly show pictures of desecrations of jesus christ. I think its just a responsible journalism. And to do otherwise i think is just playing into the hands of i dont want to say extremists on the other side but those who sort of hate islam or are very afraid of islam and want to sort of generate a lot of unease. So i sort of agree with cnn in this regard. Its no point. Its just not news. And then we get to the Biggest Issue on the table which is at the same time you had the head of the fbi saying there are too many people. I need help. I got to go to local Law Enforcement. Youve got the reconsideration of the nsa laws and youre going to take away a tool that many in your line of work say they really need which is bulk collection of data. Is this the right time to balance privacy and the ability to probe the way theyre planning to do it . No. And this is no way to figure out what sort of resources are available to the fbi after suntd when it expires. The bulk issue were going to have to come to a compromise. There has to be better oversight of it. I think the Obama Administration has come to that conclusion. The thing people have to remember is that there are other provisions that are going to expire that are less controversial than the bulk provision including the basic fact that we want our fbi agents to be able to survey phone lines and phone numbers of a specific terrorist. The laws written in a way that the fbi has to get new survey surveillance rules for each different phone number. We want it the fbi can follow the guy any number he uses. There are other parts of the provision getting lost in the news story that we have definitely got to expand or continue on past sunday. So there has to be a resolution otherwise its no way to run National Security. So dont get caught up just in bulk collection of data when theres so much else in the patriot act that needs to be reassessed and maybe reactivated. Juliette kayyem thank you. Now to the battle to retake parts of iraq seized by isis. Iraqi forces not only fighting to retake ramadi they are also locked in intense battle for a key oil refinery which has potential to turn into an environmental catastrophe. Cnn International Correspondent granted rare access to the front lines in baiji and joins us live. Nick. Reporter baiji is so vital for the attack potentially in the future against mosul thats nearby. But also in cutting off a supply route. The first target that iraq mentioned would be on its list when trying to clean out anbar where ramadi is. And we got access ourselves to Iraqi Special forces on the front line there. This is just a taste of how pock liptic it could get. Oil refinery already choking on smoke. Part of this huge complex is still held by isis. Shia fighters filmed this tuesday. The months long fight here slowed by fears of the ecological chaos isis could wreak if they scorch and burn here as they retreat. Iraqi special forces took us to their front line defending the ruins of a house that a Coalition Air strike pushed isis out of. They are from the elite Golden Division. Their ramadi colleagues part of the troops the u. S. Said lacked the will to fight. That line of buildings over there is isis closest position. And during a thick sandstorm here they used the cover of it to advance within 20 meters of here. When the sandstorm subsided suddenly a fire fight began. [ gunfire ] we dont know why they start shooting what they may have seen. Isis a few in number here they say but willing to die and have a sniper nearby. Or maybe they more want to show us and even washington they very much do want to fight. Its not logical and wrong, he says of the american criticism because anywhere in ramadi mosul or baiji, anywhere duty calls we fight. [ gunfire ] their gunfire grows. And usually its mortars that isis fire back. So we pull out. More ammunition some american is arriving at their base but the fight will be a slow encirclement were told. The reason we want to surround them is we must clean up the area properly with specialist engineers because it has fuel but also boobytraps. Isis part of bag datds new plan for ramadi but a slow grind, mindful that iraq needs something to live off if isis ever leaves. Now, when we were there we had reports of six iraqi police being killed by simply taking the wrong road. Its clearly an active front line but there are two issues really facing all operations now in iraq. The first is how fast do they move. In baiji they have a key issue about trying to stop the knee listic people of isis causing a disaster in their wake. Iraqi forces trained adequately with the mission they need with the people they need to do the job, but they also have shia fighters alongside of them. That complicated significantly more around ramadi where all those groups have to be on the same page to launch a successful offensive against groups like isis so wellequipped and day by day better dug into ramadi. Alisyn. Nick so important for us to be able to see whats going on on the ground there. Thank you for your reporting. Back here at home floodravaged texas could be in for more rain this weekend.

Mmm if you look at what i had to do when i left the race i have seven kids. I had to go to work. I had to provide food for my family. And i wasnt in front of your tv very often over the last three years. I just couldnt be. That was Rick Santorum moments after getting into the race telling cnn why his poll numbers are underwhelming at the moment. But lets look at this new quinnipiac poll that shows Jeb Bush Ben CarsonMike Huckabee marco rubio and scott walker all tied. Here to weigh in on this cnn political analyst and editor and chief of the daily beast john avlon and sirius xm host margaret hoover. Hi guys. Good morning. Lets pull up that quinnipiac poll again. Margaret its interesting that jeb bush, the presumptive leader for a long time is tied with somebody like ben carson who is new to politics. What this shows is who has been front and center on republican primary voters minds hearts and minds in the last six months. Ben carson wrote a book hes been doing the book tour going to all the early states. Jeb bush has name recognition. Mike huckabee has been on fox news and in front of all those conservative voters. Marco rubio is a really a conservative star on the republican side. And so is scott walker by the way who had three elections in four years and has been actually getting a lot of support from the National Republican donor base in order to beat off the unions. So these are all people who are front and center of the conservative primary. Margaret says front and center is this an awareness poll more than a whom do you want to vote for poll . All polls at this stage i think its fair to say are awareness polls. Whats significant isnt just the depth of the fragmentation on the republican side and the people you dont see in this poll like ted cruz who certainly have awareness benefits. But how low that threshold is and how the people actually who have a real builtin advantage like a jeb bush from a name id havent really been able to outpace, you know relatively noname candidates. The other big takeaway from this poll is versus Hillary Clinton, which is the ultimate general election gut check, the people who are closest to her within striking distance are rubio and rand paul. Thats significant to me because thats a whole different consideration set. Thats about electability in a general. Just remind people at home who actually is in the race lets do that right now. Look at the candidates who have thus far thrown their hats in the ring. So as of yesterday it was Rick SantorumMike Huckabee ben carson Carly Fiorina, this is the gop side marco rubio, rand
