of water from a public hydrant in another district. according to the complaint filed month, the district constituent $22,000 on an investigate to investigate the man who played a p.i. on tv. cnn did reach out, his representatives were told if any comments would be made. we will check back. check out our show page for video and extras. that's it for "the lead." i'm jake tapper turning you over to brianna keilar filling in for wolf blitzer in "the situation room." \s. happening now, terror plots foiled. u.s. officials say multiple attacks were thwarted but it's too soon to breathe a sigh of relief and it's a chilling new threat. number one threat. the general not nated as joint chiefs chairman says the greatest challenge so u.s. security is russia.

the flag coming down. the governor signed a big to remove the confederate flag from the state grounds. what about the hatred and violence it has come to symbolize? and for blood, a report that north korea's leader has executed 70 officials since coming to power. is his reign of pourer worse than his father or grandfather? i'm brianna keilar. wolf blitzer is off. you're in "the situation room." americans didn't know it at the time but they have multiple close calls leading up to the july 4th holiday. officials say several terror threats were foiled across the country and fitting the isis pattern they were inspired from abroad with the goal of kids u.s. citizens. even more chilling officials say the risk is still great. we're just learning of a new threat after his predecessor was killed the new head of al qaeda's most dangerous branch is

calling for attacks on the united states new fallout from the massive attack on u.s. government computers, investigators now believe more than 20 million people have sensitive personal information stolen. the main suspect? china. i'll speak with senator chris murphy and our correspondents analysts and guests are standing by. >> we are told that u.s. law enforcement foiled several attacks, including some timed to the july 4th holiday. the fbi has made more than ten arrested some tied to attacks, again timed to the holiday. even though the holiday has passed the threat level remains, i'm told very high. u.s. law enforcement thwarted several terror plots in the last four weeks. including plots tied to the july 4th weekend. u.s. officials tell crennel,

inspect director from comey say something were tied to the holiday. >> think stopped the stuff that was trying to come at us july 4th but now it's the 7th and 8th and they're on to the next things. >> reporter: they were foiled coast to coast, unfirsted, chug xlans with guns knives and other weapons, fitting isis's public calls to attack in any way possible. investigators believe that isis members overseas enabled the plots and encouraging americans to carry out attacks on u.s. soil even selecting possible targets. comey calls it crowd sourcing terrorists. senator james rich telling cnn wednesday that time was critical. some were quite imminent actually. >> within days? >> within days. there was one, of course that was even one that was within hours or minutes. >> the foiled plots come as the

fib continues to warn that terror suspects have gone dark increasedly communicated through encrypted messages that's widely available, but impossible for the intelligence community to monitor. u.s. officials tell cnn that the risk of terror attacks remains very high. >> based on recent past trends isis has beenling to and able to push out information to americans, and a small number have been willing to act based on that. >> here's a worrisome development, the fbi is seeing isis exercise more control over plot here inside the u.s. for some time they've been saying these attacks are more inspired encouraged maybe even given general ideas for attack methods and targets. now, however, they're seeing some direction from isis operatives overseas including picking targets. brianna, we've been talking for a long time about the worry of foreign fighters returns from

iraq and syria to the u.s. but when you can do this via social media from afar isis can exercise real threats here on u.s. soil. >> jim scuitto, thank you so much. stunning remarks today about the enormity of the threat posed by russia. the words sound like something out of the cold war, and they come from the nominee to be the next joint chairman of the chiefs of staff. barbara? >> back now is the commandant of the marine corps on to his next job today, confirmation to being the joint chiefs chairman president obama's top military adviser. he was asked at the confirmation hearing what his biggest concern was about national security. the answer may surprise you. >> my assessment today, senator, is that russia presents the greatest threat to our national security. in russia we have a nuclear power. we have one that not only has

the capability to violate sovereignty of our allies and to do things that are inconsistent where our national interesting, but they're in the process of doing so. if you want to talk about a nation that could poe as existential threat to the united states i would have to point to russia. >> this is w50i8 we're focused so much on work looking at iran and a nuclear program to iran the new military adviser, he is focused on russia. brianna? >> besides russia what other countries is she concerned about? >> he did talk about concerns about china, north korea, and of course his concerns about isis which is where the bulk of u.s. military involvement is certainty directed these days. on the question of iran i should point out he also very much a the same page as the current chairman general marty dempsey. he says he will maintain a military option to strike iran if the president were to order

such a strike. brianna? >> barbara starr, thank you so much. joining me we have senator murphy of connecticut, a member of the foreign relations committees. thank you so much for being with us. >> sure. >> you just heard the nominee for the chairman of the joint chiefs of staff saying russia is his main concern at this point. do you agree with that? >> that's music to putin's ears. much of his entire strategy is designed to be as much of a stick in the eye to the american government as possible. i wouldn't agree. i think that nuclear terrorism is the biggest threat presented to the united states and that's why so much of our focus is on isis, trying to tamp down their expansion of territory before they can ever have access to weapons of mass destruction, and why we are so concerned about iran. i believe that russia is a regional power. i think we should support our friends in ukraine, but i would

disagree that russia presents today an existential threat to the united states. i think it's nuclear terrorism, the proliferation of weapons outside of a place like iran that has to worry us most. >> he did range threats neglects order, russia china, north korea and isis. china we've learned is responsible for the opm hack. in fact millions of employees who had their personal information stolen. that's a lot of people with security clearance who had that information stolen. does this need to be a proportional responsible? >> i got a letter telling me that my own information was stolen and so this is personally important to me and my family as well. and they're of course has to be a proportional response. >> what is is it? >> given this was a clandestine attack it's likely our response

will be clandestine as well. this would not be a response that administration officials come on to cnn and talk about. this is probably something that none of us will ever know about, perhaps a cyberattack to the chinese as well. it is important to note though this is just a i would version of espionage in some sense and the united states has been trying to get information out of china, china tries to get information out of us but there have been generally accepted norms as to how big and bold you are. >> this pushes the line? >> this is beyond the pail. why does it seem that it keeps getting upgraded? why are we learning this snow should we trust opm? >> the defenses we have against these attacks are inadequate. we are right now trying to get a cybersecurity bill passed through the united states

congress that would give new tools both to the government and the priority companies to share information. part of the problem is that when a country like china attacks a private company, they don't communication to the government about what they have learned about that attack and vice versa. so we have an obligation to try to up our defenses. >> more questions ahead. i'm going to take a quick break. we'll be right back with senator chris murphy.

the u.s. and other world powers are still negotiating, but frustrations are showing. the white house says there's no deal yet and john kerry has stepped out of the talks, to

warn that they can't go on forever. senator chris murph,is here with us but elise lab bot, give us a sense here do you think the odds of this agreement may be receding? >> we've been talking for days they've been reaching the end game but i think this is the final stretch, and it is really the highest stakes right now. secretary of state john kerry spoke to reporters just a while ago and signaled to iran that u.s. patients is running out. take a listen. >> we're here because we believe we are making real progress toward a comprehensive deal. but as i have said many times and i discussed with president obama last night, we are not going to sit at the negotiating table forever. >> now part of this is an effort by the obama administration to show that it is not willing to take any bad deal and is willing to walk away but i also think,

brianna, it's a message to iran. secretary kerry is saying listen this is the best deal you're going to get, now you need to take it or leave it. now the finger pointing is startic. even russia iran's closest friend at these talks is blaming the possible breakdown of talks on the u.s. and europe, so a lot of chess moves going on, a loss of posture. i think this is the final stretch. this is really the take it or leave it iran message that you are hearing from secretary kerry today? >> that's right. i think we're reaching what they call the law of diminishing returns. it's been two weeks, everything is exhausted and it's the same issues that really need to be taken by a political decision a yes or no by iran. the eu foreign policy chief spoke to christiane amanpour moments ago and said this is the moment of truth. european diplomats, u.s. officials say, if iran says yes,

there could be a deal today, but if not, we need to finish this up and come home. i think the next 234 hours will be key here. >> elise labott thank you so much. we're back with senator chris murphy. nor, you were in this key meeting with president obama where he talked with senate democrats, and he said at this point he believes there's less than a 50/50 chance. what all did he say to you? >> he actually didn't get a question from democratic senators about iran. >> you were talking about a number of things and he brought it up? >> we had a general meeting on a number of subjects and he wanted to make it clear that he was prepared to walk away from the table. if this final agreement didn't look like the framework that was agreed upon some months ago. he want to do make it clear to us he was still committed to walking away from a bad deal. i guess i can understand why the iranians are having some trouble finally saying yes.

this does rep a paradigm shift in tehran. it would be the first that the hardliners have lost any substantial issue inside that government. and so i think kerry is seeing progress being made and understanding it may take a few days for the supreme leader and zarif to finally put pen to paper. >> he said today the negotiations aren't going to go on forever. at some point basically you have to wrap this up or walk away. at the same time he said they're not open-ended. he didn't exactly say they're closed in a way, that there's no timetable for when he would say, you know what? enough is enough. >> the consequences of the negotiations falling apart are potential catastrophic. you're going to have elections coming up. the hardliners would likely win to put the country back on a path. it would be difficult to get the sanctioning back in place.

you're already hearing the russians trying to put the blame on the united states suggesting they may not sign up for the next round, so he's going to give this every chance but i think a point will come when there's no progress being made and when that moment comes, he has to walk away. >> you've seen you've heard the supreme leader do you trust the iranians in this negotiation? >> no way. none of us should trust the iran yawn which is why we snead an inspection regime that is unprecedented, but i also don't trust what the supreme leader is saying publicly is what he's telling his negotiate orr. right before the framework he said he needed 90 centrifuges. >> so posturing? >> they may by posturing. he may have been captured by the hardliners. maybe we should give it a few days a week longer to play out. we learned fred from the fbi director there were several threats to kill americans that had been thwarted here in the past several weeks. we heard from senator jim rich

yesterday. he said some were imminent. i said how imminent? hi said within hours. what can you tell us? >> we know these plots were fairly unsophisticated. >> by that you mean guns knives other weapons -- >> not plots that had been in the works for months and months. that doesn't give us any solace that shouldn't make us any less vigilant. it just suggests that the intelligence that we've always had that there aren't any sophisticated attacks being planned against the united states from syria and iraq seems to remain to be the case. that's why we need to take them serious lid. it doesn't take a exist indicated plot for hundreds tore killed. >> or completely to be terrorized. the idea you could be going about your normal activities, either on a holiday or just a normal day, and you are perhaps threatened by someone with a gun or knife.

>> which is why we need to pay attention the tools with which isis uses to recruit people. a lot of us having skeptical about calls from republicans to send tens of thousands -- we ultimately think that becomes more bulletin board material for terrorist recruiters so the way in which we fight it has to be a strategy -- but doesn't actually inspire more people. >> to you that's disthor are recruiting moments? >> i think we need to degrade and defeat them but we also need to pay attention to the reasons why people are signing up and we need to give in general, terrorists lest reasons to recruit, not more. >> isis has called for there to be attacks during the hole monday of ramadan. we're p.o.w.s the july 4th but can americans breathe a sigh of relief? >> no we can't, and it's not just isis. we know al qaeda and affiliates

are trying to actively plot attacks against the united states. we need to be vigilant here at home. the reports showed quite correctly they're coming out of the social media. out in the open conversations. it's why a lot of is supported an extension of a reformed p.a.t.r.i.o.t. act, because we also understand that we do need the ability to listen in on these guys. >> before i let you go senator rich said yesterday one of these attacks will come to fruition and that is just going to happen at some point you can't really stop all of them. do you agree? >> i don't think we need to accept that as an inevitability. people have been saying that since september 11th. maybe it's remarkable, but one of these more let's say smaller plots? >> so the lone wolf attacks -- with you don't necessarily have the intel, they sort of come to be without any specific connection about the target to isis on some other terror group?

do you reject that idea? >> refuse to accept the inevitability of one of these attacks. we have tools and tactics to try to degrade them. let's keep our goals and our objectives high. >> senator murphy really appreciate you being with us. >> thanks a lot. coming up new information on terror plots thwarted in the u.s. the fbi director says they were meant to kill americans, and officials say the risk is still very high. >> and why the republican establishment is so worried about donald trump. party leaders tell him to tone down his comments so how much damage could he be doing? you're in "the situation room."

our top story, u.s. officials say that multiple terror attacks were thwartsed before the july 4th holiday and the fbi director says they were meant to kill americans. joining me to discuss this cnn national security analyst peter bergen cnn justice correspondent pamela brown, and cnn law enforcement annualist and former fbi assistant director tom fuentes. pam, you were in the room with the fbi director. what did he say? >> he said the fbi thwartsed terror plots, isis-related plots that were linked to the fourth of july. there was a lot of talk about terror threats around the fourth and the fbi director james comey said today in fact with 1e6r8 arrests leading up to the fourth they were connected to plots thamp -- that these people were planning to set off on the fourth. he talked about the fact that there were more than ten arrests in the past four weeks and some

were linked to the fourth of july plots and also said that some of the people arrested had been in direct communication with isis fighters that were directing them with specific plans on what to do. >> what about the size of these attacks? >> i asked him about the size of the actual plots. he wouldn't go into that and how many they were essentially. he stayed mum on that but we heard from congressman mccaul today, that their concerns were about the new york/new jersey cell they wanted to set off explosive as july 4th parades, possibly near military members. our indications is there was nothing imminent they suspects didn't have anything ready to go to set off. >> tom, we've learned that isis is using the dark web, they're using encrypted messages when they're talking to recruits and they're talking to people inspired by them here in the u.s. so how are these plots being

thwarted if the u.s. has broken this encryption? >> normally on those apps you cannot break the encryption but they go on social media to brag about what they're going to do and that's when they get them. when they get specific using those apps they can't monitor that, but it's when they're not using an app or making regular cell phone calls, they have. one of the taps you heard about that they said was within hours or minutes was five weeks ago in boston the osama ra him, that the fbi was monitoring they saw his e-mail traffic ordering online large hunting knives military-style knives and they heard him call his partner at 5:00 a.m. and say i can't wait he's not waiting for the fourth of july knolls waiting for anything i have to go out today, the boys in blue are waiting so presumably he was going to kill a boston police officer that day and that you have june 2nd. he leaves his house, they approach him, he draws a knife

and they shoot him dead. >> how did isis become so proficient at these technologies? >> think about the typically leader of isis right now, a western, middle class, relatively well educated, they're advocating using tools that are part of the dark web and providing encryption you know the keying. they're also -- also they're encouraging people to direct message them privately on twitter and uses apps like kick or wasupp and others. it's a generational thing, not that complicated. >> it's a generational thing. we heard from the new leader of aqap arguably al qaeda's most dangerous branch he gave the first speech since he succeeded al what harbi.

>> his last name indicates he's from yemen, which is unusual. a former military commander, part of the prison escape part of the inner circle. interestingly he said i'm pledging allegiance to the leader the al qaeda, not isis so it remains in the al qaeda ambit. >> senator risch yesterday said it's a matter of time until we see a tunisia style of attack here in the u.s. do you agree with that? >> sure. how do you prevent it? 300 million guns in this country and a couple thousands of these that believe in this ideology put the two together. it's going to happen at some point. >> very sobering. thank you so much. next one more night, that's how much longer the confederate flag will fly on south carolina's statehouse grounds. i'll ask the head of the naacp

signed a bill to remove the confederate flag. it comes down tomorrow morning at 10:00, taken to a museum. it was just over three weeks since a racist gunman who posed for pictures with a confederate flag killed nine people at a charleston church. we have cornel william brooks with us. this was such a big moment. you grew up in south carolina so i think you have a personal connection to what this means. >> very much so. >> i think this is an extraordinary day, though this is a symbolic victory, it is an important victory. now dr. martin luther king once spoke about a day in which the sons of former slaves and the sons of former slave owners would be able to sit at the table of brotherhood. this is not that day, but it is a day in which sons and daughters of the confederacy, sons and daughters of an enslaved people can gather

around a flagpole of inclusion with no confederate flag around to be seen. >> we're not at the dame that martin luther king talked about, so it's a step? >> a symbolic step. >> what more needs to be done? a symbolic victory, but they can't consider the only discrimination at the top of the flagpole but the racial forces that put that flag there. >> will you lift the boycott of south carolina? >> absolutely. we have maintained this boycott for 15 years running.

we have to commend the grassroots leadership fraternities so errorities the united autoworkers. the n -- the national association of -- the ncaa from their steadfast commitment to maintaining it boycott. when the flag comes down we lift the boycott, we look to entertain an emergency resolution at our convention in philadelphia so it's important. >> which is when? >> it is this coming weekend. >> as of this weekend, you expect the boycott will be lifted? >> indeed. we're also looking to shift the battle. so we have a number of other states that maintain these emblems of bigotry and violence. as we move to other states we're looking to move beyond not just the flag but to the real civil rights challenges before

the country. >> i want to ask you about baltimore. we've seen big news there yesterday, the commissioner of police fired. he had been criticized for his response. what is the reaction to that and what else needs to be done? >> sure i think the mayor, the rank and file police officers certainly the citizenry in baltimore would agree, that the challenges there are not merely a matter of rotating the personalities or leaders atop the police department but addressing the policing culture in the city of baltimore, and so you have to have not only top-down accountability but bottom-up responsibility. those who took freddie gray's life were range-and-file police officers. we have to create a culture that engenders community trust. that's what works. criminologists tell us that police commissioners tell us that that's what we have to work on bottom-up reform.

i want to ask you as well about bill cosby. i'm asking because he's someone who -- his show changed really the perception of african-americans, certainly the portrayal of african-americans on television and he's been exalted as really this example in the past presidential medal of freedom, he has a star on the hollywood walk of fame. do you think in light of what we have learned that he should be stripped of some of these honors? >> well here's what i want to make clear here. the naacp is the nation's preeminent civil rights organization. at the heart of civil rights are women's rights. that certainly means the right to have your body your integrity, your spirit respected and protected. rape violates all of those. so our values stand in opposition to any form of violence against women. so those honors many them were

given years ago. those organizations have to make those determinations, but we have to be clear, the naacp stands very firmly against violence perpetuated against women. that's where we are. >> cornell william brooks with the naacp, thank you very much. really appreciate it. >> thank you. reign of terror new details about dozens of executions since kim jong-un took over. and the republican start's growing alarm over donald trump with allegations that rapists are coming across the border from mexico. will he tone down remarks like this? do you think? >> it is rape. and it's happening, and it's a shame, and it's horrible.

developing now in politics a growing sense of alarm among the republican party establishment as donald trump continues thundering away about mexico immigration, and undocumented workers. cnn's senior washington correspondent joe johns is keeping track of the latest fallout here. >> brianna, he's given a barrage of interviews and now there are mixed messages about whether the chairman of the republican national committee actually asked donald trump too tone down his rhetoric just ahead of a newly announced visit trump is expected to make to the state of arizona which has been ground zero in the debate over immigration. one call two very different stories. donald trump pushing back against reports that republican national committee chairman priebus asked him to back off his rhetoric about undocumented immigrants. >> we didn't discuss that.

he did say, perhaps you could tone it down a little bit, if that's possible but i also know it's your personality and you are who you are and that's the way it is. >> reporter: trump said the call was quick and positive. >> it was a very brief call and it was a very nice call and it was more of a grat la tore call than anything else. >> reporter: but a republican source tells cnn's dana bash that priebus talked with trump about a range of issues and voiced concerns about the damage he's doing to the republican brand. >> they're bringing drugs, they're bringing crime, they're rapists, and some i assume are good people. >> reporter: according to the source priebus told trump, "look, i got to tell you, i spent four years trying to make inroads with the hispanic community. how we address immigration is very important to winning back hispanics politically." >> those particular comments are not helpful. >> reporter: meanwhile, trump, not backing down in an interview with cnn wednesday. >> we bring them back and they

push them out. mexico pushes back people across the border that are criminals, that are drug dealers. >> reporter: trump's defense comes as protesters descend on the site of his new washington, d.c. hotel. just blocks from the white house. >> donald trump has got to go! >> reporter: trump told cnn's anderson cooper he could not guarantee all his employees are in the country legally after "the washington post" reported some workers at his d.c. hotel acknowledged they were undocumented. >> i can't guarantee it how can anyone? we have 34 million in the country. >> reporter: that hotel will no longer feature a restaurant from celebrity chef and spanish immigrant jose andreas. he's backing out of the project, citing trump's recent comments. the trump team is already threatening to sue. the real fallout at the hotel in d.c. has more to do with trump's business partners who are backing out of the project. the latest is jeffrey zakarian who is the culinary director of the plaza hotel in new york.

he was teed up to put a new restaurant in the trump hotel in d.c. but put out a statement saying trump's statements do not align with his core personal values and he wasn't able to move forward. >> trump says this money means nothing, but i don't know it seems there's this snowballing effect we're seeing. >> it keeps adding up. he's a businessman. >> he is, bottom line matters. tonight a new glimpse into the ongoing reign of terror inside kim jong-un's north korea. cnn's brian todd is are is here with some pretty disturbing new details. >> a frightening glimpse and one with broader implications. tonight the nominee to be the next chairman of the joint chiefs of staff warned congress that north korea ranked above isis in terms of threats facing the united states. we have new information tonight on just how much of a threat kim jong unis to those inside his country. he's forceful reckless and has a thirst for power that amounts to a reign of terror according to a top south korean official. north korea's young dictator kim jong-un has executed 70

officials since coming to power in late 2011 says the south korean foreign minister. by most accounts that's shockingly more than were executed by his father kim jong-il. >> unlike his father he exhibits a ruthlessness here by his actions, by the things that he's prepared to do that his father simply was not prepared to do or didn't feel the need to do. he does. >> reporter: kim executed his own uncle and reportedly his defense minister. human rights monitor greg scarlotta says the regime often uses grotesque methods. >> they're zuted by 50-caliber anti-aircraft machine gun battery. the bodies are pulverized. there is nothing left behind. >> reporter: u.s. officials tell cnn executions are kim's way of solidifying his position. one official calls them a crude mechanism for internal control. analysts say the purges may show that kim feels vulnerable but he's also sending a bone-chilling signal to those in

one's public sues are considered betrayers if they cry at the event. very often they sit their watching their loved one be executed, completely stone-faced. one analyst says we need to watch out about how long this pattern of execution continues under kim jong un. if they go on much longer he says those around kim may get nervous enough to move against him. >> maybe consider defecting. it's important to note that it really doesn't seem to take much. minor transgressions will get people executed under this regime. >> absolutely, they will. and just the accounts of the executions this year bear that out. just this year the ministry of forestry was executed for expressing dissatisfaction with the country's forestry program. the vice chairman of the state planning commission was executed because they objected to changing the design of a science and technology hall from a round shape to a flower shape. kim jong-un executed members of an orchestra for a scandal they were involved in. just this year. you don't have to be high up and
