feet past the u.s. port of the entry. there are rows of migrants here sleeping on the floor because they want to be the first to get in line to seek asylum from the u.s. when the doors open this morning. you can see there are several people here already waiting on the outside of this. these people are here from mexico seeking asylum. some of them tell me they've been waiting for up to ten days. and there's no guarantee that they will actually get in. a showdown at the border. as the caravan of central americans attempted to cross into the united states sunday. some climbed the border wall but didn't cross over to draw attention to their ultimate goal of asylum. nearly 200 people lined up to show support. mailygn charlotte prado is seeking asylum because of violence in her country. the truth is, there are daily killings and violations of human rights. at one point, the group swelled

to about 1,000 people as they made their way north from central america to mexico to tijuana. along the way, they crammed on to trains and buss with a few belongings they could carry. the caravan is now down to around 200 people, many traveling with children. >> watch the caravan. watch how sad and terrible it is. >> reporter: president trump has warned they will not be allowed in the u.s. >> i call them the dumbest immigration laws anywhere on earth. if a person puts their foot over the line, we have to take them into our country. lawyers are telling them what to say. >> reporter: immigration lawyers deny they are coaching the migrants. on the u.s. side of the border sunday, dozens gathered to show their support for the referees. >> we have i think a legal obligation to hear these claims of asylum. the way he's used the caravan to stir up anger, hatred and racism in the far right, it's concerning and it's offensive. >> reporter: border patrol agents say they did catch

several people illegally crossing into the u.s. that are associated with the caravan. they were climbing over a scrap metal border fence. we know the people that are staying here and waiting to seek a p asylum, right now a lot of them have white arm bands on. they feel they have the best case scenario for actually being granted asylum to come into the u.s. and they're asking those cases take priority today. john. >> mireya, so what happens next with those who take priority or any asylum seekers? >> so for these cases, people have to prove there is a credible fear that if they return to their home country, that something might happen to them. right now, we understand that there are roughly three quarters of applicants that apply actually get through that first initial process. they speak to an immigration agent as well as an immigration judge. if they can prove that and move on to the next round, there is a chance that they will go into a detention facility and there's a possibility they could be split up from their families if that

happens. some people are allowed to stay in the united states with family with ankle monitors to make sure they know exactly where they are at all times. this entire process could take several months. >> very long road ahead, thanks very much, in tijuana, thank you. president trump says a summit with north korean leader kim jong-un will probably take place in the next three or four weeks. possible locations for the meeting include singapore, the trump administration's choice, or mongolia, which kim could reach by train. at the white house, officials are cautiously optimistic. good morning. >> reporter: alex, good morning. the trump administration acknowledges north korea has kept its promise to stop conducting more missile tests but quickly adds it will not be naive when and if negotiations begin, given the country's record of brokering, then breaking deals. >> we're not going to take words. we're going to look for actions and deeds.

>> reporter: secretary of state mike pompeo said kim jong-un must prove he's willing to meet the administration's demand. >> does he want the pressure campaign to continue or is he looking for something big and bold and different? >> reporter: president trump says he won't accept less than full denuclearization. it's unclear how kim interprets that. in exchange, kim wants sanctions release and a promise the u.s. won't invade north korea. >> president trump is determined to see this opportunity through. >> reporter: on "face the nation," national security adviser john bolton wouldn't say if the u.s. would make any promises. >> we want to see real commitment. we don't want to see propaganda from north korea. >> you haven't seen such action so far? >> we've seen words so far. >> no dismentalment? >> we've seen words so far. >> reporter: kim claims he will shut down the country's nuclear test site in may and open the door for the u.s. to inspect activity but the regime has made promises before. in 2008, north korea blew up a

cooling tower at its nuclear power plant to show its commitment to stop making nuclear weapons. when diplomatic talks fell apart, the north conducted new tests. >> i think we'll have a meeting over the next three or four weeks. >> reporter: at a speech in michigan saturday night, president trump took credit for friday's historic summit between kim and south korean president moon jae-in. >> saying, what do you think president trump had to do with it? i'll tell you what. like how about everything. >> reporter: we expect to hear from the president later this afternoon. he is hosting the president of nigeria here at the white house. and the two are scheduled to hold a joint press conference. >> norah, thank you. ben tracy is in beijing with north and south korea's newest steps to build on their historic summit. ben, good morning. >> good morning. a lot of heads are still spinning as kim jong-un continues to attempted transformation from dictator to diplomat.

in addition to promising to close north korea's main nuclear test site next month, kim jong-un also seems to be acknowledging for the first time that denuclearization to him actually means giving up his weapons. according to the south koreans, kim said of the summit that if we receive promises for an end to the war, he's talking about the korean war, and a nonaggression treaty, then why would we need to live in difficulty by keeping our nuclear weapons? in a gesture of good will, north korea is going to match its time zone to south korea's. kim jong-un moved the clock's back 30 minutes to what became known as pyongyang time. south korea said it's going to remove the massive loud speakers at its border with north korea that were used to blast propaganda. the two countries say they want to turn the dmz into what they are calling a genuine peace zone. now, meanwhile, china has largely been on the sidelines while all this diplomacy has been happening. they're hoping to get back in the game this week by sending their top diplomats to south

korea, john. >> ben tracy in beijing, thank you. isis claiming responsibility for a double suicide bombing near nato headquarters in afghanistan's capital. at least 25 people were killed. police in kabul say one hour after the first blast, a second attacker, posing as a journalist, set off a bomb in the middle of reporters who had rushed to the scene to cover it. nine journalists were killed, including shah marai, a longtime photographer for a french news agency. wireless providers t mobile and sprint are planning a $26.5 billion merger. t mobile would acquire sprint using stock instead of cash. if regulators approve the deal, cell phone customers in the u.s. would be left with a choice of three national providers. leigh gallagher, fortune's editor at large with us. this could mean 1 million subscribers for this joint company. >> it's a big deal. this puts these numbers three

and four together to really challenge the number one and two, which have a combined market share of 70% between at&t and verizon. so what the companies are saying is that this will -- you know, it's harder to compete. they need this to become, you know, competitive. especially as there's such an incredible race going on for the next frontier of technology which is 5-g networks. what's interesting about this deal is the way they're positioning it. they're positioning it actually as this is better value for consumers and this will be better for the marketplace in general. they're saying that our technology will be better when it's merged and when we can invest more. they're saying they're going to spend a lot. they're playing to the heart strings of some very topical issues now. they're saying we're going to hire a lot more. we're going to help lead america in the race for 5-g. >> in fact, sprint's ceo says going from 4-g to 5-g is like

going from black and white to color tv. >> this is a very big deal. this is what's going to power the next generation of all these technologies. everything from autonomous cars, augmented reality, internet of things. this is coming. it's a major, major investment. this is billions and billions of dollars. and they really needed to -- they do need to join forces to be able to better compete. >> they're talking about creating more jobs. put that in context. they're doing all this new stuff, but there's a lot of churn, right? >> there always is. they're going to have some overlapping retail stores. on the other hand, they say they're going to push more into rural areas. they're saying they're going to save about $6 billion in operational costs. and they're going to spend $40 billion over the next three years. >> they also make the case about china which sounds like a message to the administration which is going to have to okay this deal is that how you see it? >> yes, these are as, you know, again just playing right to the heart strings. they're saying this will be america first and that this will, you know, 5-g is something the white house has already said is a national priority. and here they can say, you know,

we're not going to cede this with china. by them entering the game combined, that will accelerate the race toward 5-g. >> there is a japanese bank that is involved. >> in fact, soft bank, which controls sprint, he has wanted this ever since he took control of sprint. >> a lot of parties involved. >> he did meet with the president right after the election and said, i'm going to invest $50 billion in america. >> okay, we will see what happens. leigh gallagher, thank you. the white house correspondents association says critics of saturday night's annual gala have a reason to be upset. the group says an edgy monologue by comedian michelle wolf was, quote, not in the spirit of its mission. wolf made jokes about the media and the president, but her mocking of white house press secretary sarah sanders caused the strongest backlash. mr. trump called wolf filthy. vladimir duthiers of our streaming network cbsn is here with response from critics and supporters.

>> reporter: the white house correspondents association bills its annual dinner as a way to raise money for journalism scholarships and honor work of washington reporters. it's the featured entertain they're normally grabs the following morning's headlines. some say this year's host hit new extremes. >> it's 2018 and i'm a woman so you cannot shut me up. unless you have michael cohen wire me $130,000. >> reporter: michelle wolf didn't pull any punches during her 19-minute routine. her toughest jab seemed aimed at white house staffers including press secretary sarah huckabee sanders. >> i actually really like sarah. i think she's very resourceful. but she burns fat and then she uses that ash to create a perfect smoky eye. >> reporter: some female journalists said wolf unfairly criticized sanders' physical appearance, calling the routine deplorable. >> i have to say, i'm a little star struck. i loved you as lydia in the

hands maids tale. >> reporter: others came to her defense calling her hilarious and funny. speaking on cnn the next morning, white house correspondent association president margaret talev stood by her decision to feature wolf. >> do you think she crossinged the line? >> i think that she brought to the night what she thought was important to say and her goal may not have been press unity and everyone rallying around the room to support journalism. >> reporter: in a conversation with cbs "this morning saturday" wolf previewed her routine. >> comedy shouldn't be about what you want to hear, it should be about what you didn't know you wanted to hear. >> reporter: on twitter, president trump, who was not in attendance for the second year in a row, called the event an embarrassment to everyone associated with it. put dinner to rest or start over. he also made reference to the 2011 dinner, being roecasted by obama. >> no one is happier, no one is prouder to put this birth certificate matter to rest than

the donald. he can finally get back to focusing on the issues that matter. like did we fake the moon landing? >> reporter: talev says the association does not review the comedian's monologue before delivered. wolf defended herself on social media saying the standards jokes were about her despicable behavior. she later posted a picture of herself on instagram saying she is not in the spirit of the mission. >> well, they need to look clearly about what the mission of the white house correspondents association, and i think part of it includes civility and jokes are fine but there are some stuff that's below the belt. >> also if one side thinks we're too cozy with the people in the administration and the other side thinks we're giving a platform to attacks that are vulgar, turns out we're doing something that is not our core job, which is defending both sides, not in the service of our job, something they certainly need to rethink. >> it is about scholarships, right. that's what the dinner's about. that gets completely lost in the

course of all this. so maybe it is time for recalibration. >> indeed. >> thank you, vlad. a massive wildfire north of phoenix threatenps at least 500 homes this morning. the tinder fire spread rapidly, covering 8,000 acres over the weekend. multiple structures were destroyed. the county sheriff ordered mandatory evacuations. cell phone video shows dark plumes of smoke. strong winds today and tomorrow are expected to make it harder to control the fire. the cause is under investigation. many people trace their family trees online, but is it right for police to do so with them? coming up, how the capture of an alleged serial killer raised a concern about the privacy of dna testing and g good morning. checking out some neat views from the roof camera this morning. we have a mix of sunshine and cloud coverage. that will be the story throughout the day today. the radar is showing clouds

>> i'm john dickerson with norah o'donnell. gayle is off. welcome to monday. a group of nearly 200 central american migrants is waiting outside san diego to learn if its members can get asylum in the united states. the caravan reached the u.s./mexico border yesterday. their journey has become a focus of the immigration debate. president trump has used them to criticize u.s. immigration law. >> the caravan made its way north from central america through mexico to the border city of tijuana. mireya villareal is there. good morning. >> reporter: good morning. this group has been traveling for nearly a month through central america. you can see right here they have been traveling on foot. they've been traveling on bus and on train. and now they are sleeping on the cold, hard floor because they want to be the first in line to seek asylum from the u.s. when the doors open later on this morning. now this group where there is a

lot of young children here involved, have been told that the border crossing facility here in tijuana does not have enough room to accommodate them all. these migrants have told me that they will stay until every one in their group has been processed. to get background on the process which can take several months, asylum seekers have to prove they have a credible fear of persecution in their home country. if they pass that initial interview they'll have to make their dicase to a judge. the caravan has caught the attention of president trump's administration and the president himself has repeatedly attacked the group saying it shows the country needs tougher immigration laws. in 2016, immigration courts granted roughly 43% of requests for asylum. now speaking with a number of people here in this crowd nearby, some of these people are from mexico. they are not part of the caravan. they tell me that it's roughly been about ten days of them coming here to seek asylum and they have yet to make it across.

>> mireya villareal, thank you. national security adviser john bolton says the trump administration isn't sure if north korea will give up its nuclear weapons. south korea says north korean leader kim jong-un pledged to give up the weapons during friday's historic summit. kim wants the u.s. to commit to a formal end to the korean war and to pledge not to attack the north. >> on "face the nation" bolton would not commit to making that deal in potential talks between the u.s. and north korea. he said the u.s. has seen positive steps but wants concrete action. >> they've said that they're going to give up nuclear testing and ballistic missile testing. they haven't conducted any recently. that's true. that could be a very positive sign or could be a sign they've reached a level of development where they don't need testing now. we've seen this in other contexts as well. president trump is determined to see this opportunity through. hopeful that we can get a real breakthrough. but we're not naive in the

administration. and a lot is going to ride on this meeting with kim jong-un. >> bolton said a planned summit between president trump and kim would also involve north korea's chemical weapons program and american prisoners in that country. secretary of state mike pompeo is flying back to washington right now after his first overseas trip as the country's top diplomat pompeo left amman, jordan, following stops in belgium, saudi arabia and israel. pompeo repeatedly accused iran of destabilizing the middle east and in tel aviv yesterday he told israel's prime minister the u.s. could help limit tehran's influence. >> strong cooperation with close allies like you is critical to our efforts throughout the middle east and indeed throughout the world. we remain deeply concerned about iran's dangerous escalation of threats to israel and the region and iran's ambition to dominate the middle east remains. >> pompeo repeated president

trump's warning the u.s. will withdraw from the iran nuclear deal unless it is improved. the president is expected to announce its decision by may 12th. the white house correspondents association is telling critics that saturday's roast by michelle wolf was not in the spirit of its mission. some of wolf's sharpest jabs were aimed at white house press secretary sara sanders sitting nearby in place of president trump who skipped the annual dinner. wolf targeted sanders' appearance and character. >> every time sara steps up to the podium, i get excited because i'm not really sure what we're going to get, you know, a press briefing, a bunch of lies or divided into softball teams. >> wolf said the sanders jokes were about her despicable behavior. in a statement the correspondents association recognizes the concerns of members and is committed to hearing from its members on the format going forward. on last night's "the circus"

on showtime, mark mckinnon and i talked about her serving as the president's voice. sanders discussed why she feels the president is his own best messenger during an interview last week before the correspondents dinner. >> thanks for meeting withous a busy day. >> the week has been pretty wild. >> when history looks back on this week, what will be the singular thing that people remember about it? >> if there was one takeaway particularly that we would like to see people focus on, it's the leader that president trump has become. he has developed great relationships from president macron to president xi to abe. i think that will be the big takeaway that you see from this week on a number of fronts. >> yet, in the middle of this week, the president decides to call into fox & friends in 30 minutes. what does he think he gains by doing that? >> we've said many times whether it's through twitter or whether it's calling in to a tv show,

the president is going to be his best messenger. >> why not maenention any of -- didn't touch on any of the international work he's been doing. >> one of the reasons america loves president trump is because he's not what we have seen in the past. they voted for him for the purpose of having somebody come in that was totally different than anything we've seen before. so it can be more challenging but it's also a lot more fun. you never have a dull moment in this white house. the president is the president because of that uniqueness. i hope that he never loses it and never gives it away because it's one of the reasons he's in the white house. >> i'm not sure she's entirely resolute in wanting the president not to lose some of the curveballs. it's a difficult dance that they have to do every week in that briefing room. >> he's in the white house but also why his approval ratings and the opposition to him which is fueling some difficulties for republicans in the off year

elections. >> doesn't make the investigation less complicated either when the president calls in to "fox & friends" for half an hour. >> you find her impressive in person? >> i find her unflappable at the podium. she's very warm and working really, really hard. >> defending the president. >> yep. >> all right. nice to see that. >> thank you for showing it. space tourist flights appear to be one step closer this morning. >> command engine start. 2, 1 -- >> owned by jeff bezos, the he laurened a rocket to thej of space nearly 66 miles above earth. it carried a capsule designed to hold up to six people. a dummy inside known as mannequin skywalker is being used to measure the possible effects on a human passenger. after four to five minutes of weightlessness, the capsule floated back down to earth. it touched down safely 11 minutes after launch. the first human flight could be

one. >> most typically use docking stations. they can cause millions to install and maintain. the dockless ones require no taxpayer dollars and can be used anywhere. >> i hate when they're scattered all over the sidewalks. >> in san francisco, that's become a problem. while the city rolls out a permitting plan, cease and desist letters were sent to three companies to satisfy state and local requirements. the companies say they'll work with the city. people are picking them up, rising them on the streets and sidewalks, impedesing pedestrian traffic and parking them in the missal of a street othe sidewalk in doorways, really impedesing people's progress and walking on the sidewalk or getting in and out of buildings. it's creating a real public nuisance. >> reporter: coronado near san diego also deemed them a public nuisance. >> they throw them on the ground. it's basically litter. >> reporter: after impounding at least 55 of the scooters, austin, texas, passed an

1987 and had-i prime-time on fox in 1989. former cia and nra director michael hayden believes they're under stress from outside forces. he led it throu. hayden's new book is called "the assault on intelligence: american national security in the age of lies." it argues the white house makes the intelligence job even harder. he said about isis, his administration has done a great job of ridding isis, but there's been a double attack. where do things stand? >> a few more forces, maybe a little more local commander authority to get things done on

the battlefield. folks like me celebrate that. i call it obama plus. a little bit more energy, a little bit more freedom of action. but this is a long-term battle. this is not one where you start spiking the football. and so you see in syria, we're not yet done and the local commanders are trying to say it's not time to turn the lights out and here in afghanistan, actually, john, afghanistan is probably a condition to be managed, not a problem to be solved. we're going have to keep the level of violence there down to an acceptable level, i think, for a very long time. >> we're on the've of a historic summit between president trump and the north korean leader, saying they're willing to give up the nuclear program if there can be peace on peninsula. do youing are believe that north korea will give up their program? >> i want to be hopeful.

we've been pretty much at this exact spot three other times under three other administrations. that's not sayle. the economic pressure, all good. the rhetoric last summer may have made us more dangerous than we had to be, but we're moving in a direction. one thing i point out in the book, is what's the intelligence backdrop to the american a negotiating position. if you look at people currently in office and carefully reeds what they say, they make the point that it would almost be irrational for kim to give up his weapons and anything like the current strategic circumstances. so when we say denuclearization, i hope this intelligence

estimate is included what our expectations are. >> in addition to that, we heard them talk about verification of that denuclearization, which is a further step. >> i think the art -- these are wicked problems. you don't need a president saying i and i alone. they're still here because they're hard and they're still going to be here after he leaves in one way or another. so, again, i hope we have muted expectations -- realistic expectations here. >> the book is called "assault on intelligence." what do you make of the president's relationship? >> it's had a bit of a rocky road. a good friend of mine and i use this as an outline in the book. john mclaughlin says it's gone through four stages. first he was ignorant.

he didn't know anything about the community. that's not uncommon, but i think it was an extra dose this sometime simply because he and members of his team had no experience in government. it quickly went to confrontation because the first time we had to meet him and discuss was over and issue that other people were using to challenge his legitimacy as president. now it's inevitability. we can't live without. we're existing comfortably, uncomfortably. >> he still calls the investigation a which hunte. >> i know. some days are good days. some days are bad days. the core here, even in this co-existence is the president's view toward truth and reality and that's the point i try to make in the book. we've had presidents who disagree with us, presidents who lie. we've not had presidents for whom objective reality doesn't seem to be compelling.

>> people would push back and say in terms of the intelligence agency, you'd say it's a slam dunk. there was not truth told about that and the intelligence committee says there were all kinds of untrookts, so there was an underlying ground truth. >> look, john, i guess it. hard work. but that's an argument about the truth, that's an argument. i'm saying over here we have a trend line that seems to want to make decisions not on a reality. the muslim man, remember, about a week out of the gate because why? because we had that with a vetting system. no reality whatsoever. by the way, you don't see the intel community, even the ones currently in government arguing for that. it with us made based upon

something else. not an argument over objective reali reality. >> what about the fact that the president made the choice to retaliate against them based on the intelligence. >> he absolutely did. i see evidence when it comes to implements back to the necessity and inevitable. they go to the intelligence with how to go do this. i hope it did, but what i didn't see was it wasn't a question to the intelligence community for the broader context like why did he do that. is he scared or is he overconfident? what were the iranians thinking? micha micha michael gerson. he has a great frachlz he says the president lives in the eternal now. the purpose of intelligence is

context. it's all about history. it's all about consequences and hence the challenge we have. by the way, i talked about the phases. woe went from ignorance to opposition to acceptance, inevitability. phase 4 is when the muller report finally comes out. >> do you think he'll accept it? >> that's why phase four is different from three. we don't know what it is and what the response will be. but right now the president has been chipping away, making more institutions. can that spread again because he's done it before to the intelligence community. the point i try to make in the book to people still in government is in addition toll your own conscience and being who you are, you are sponls for these institutions. for their survival. you cannot accommodate so much to the peculiarities and quirks

of any one president that you delegitimate it for the history of people and future presidents. >> general hayden, always good to have outhere on hot spots around the world including russia's campaign and how they're trying to influence the election. thanks for being here. congrats on the book. it goes on sale tomorrow. also right here rngs former secretary of state kocondoleezz rice will be with us. this morning lucy liu is in our toyota green room. ahead why she calls good morning. cloudy and cool for a lot of us with a bit of a breeze at the beaches. it will feel much cooler there. we have a low hanging to the

"watson." she confronts holmes about the bizarre behavior after a death. >> you've been acting like a jerk and when i called you on it, what was your response? avoiding me for weeks? we're not doing this on your terms yochl roy tonight talk, that's fine. it's an open room right here. >> i'm not well. i'll tell you everything. just not here. >> ah. lucy liu. what a tease. >> good morning. i'll tell you everything. blind everybody. last season sherlock holmes is suffering from hallucinations and now he's ill. what's wrong with him? >> wee find out sherlock played

by lee miller is basically suffering from concussions so his mind is not his own and it changes the game up because he's the one who innately knows and detects and is able to discover and come up with ideas that nobody else knows of basically whodunit. so what happens when he's not on par with his usual self. >> how does that affect your relationship? >> i think that he has to also be able to trust and be open to more people's opinions and he has to also rely on watson as a friend and also be open the being vulnerable because it's very scary when you can't be who you are at your best and that's all he knows. so suddenly he's in a situation where, you know, he can't trust if he remembers or if he did speak to someone. it becomes very scarifying. >> his chief tool is called into

question, his brain. >> yes. >> you said the character watson is the most patient role you've ever played. >> yes. >> what does that mean? >> she was a silver companion. she's more of a witness than someone who i've played before. she was very decisive and aggressive and colorful. >> impatient. >> yeah. it's a different way to sort of discover a character, and so this is a very patient character as far as i'm concerned, in my career at least. >> does this new role in filling the gaps in holmes' environmental calling more for watson? >> she has to be more aggressive as a friend and make sure he listens to her and she's able to take care of him more and i think he's so independent and fiercely independent where she sometimes has to come in and say i'm going to do this and you're going to do this.

>> you're also directing two episodes of the show. >> this season i directed two episodes and starting from season 2 i was directing. so i've had a great opportunity to be a great part of a didn't side of the show, which i've enjoyed? >> i love acting. i don't know if i'll ever stop. but i have grown to appreciate directing because you get to work together in a team environment with the head of departments and crew and everything comes together and the co-harris of that really opens up your world and you really are activating every part of your brain. >> let's talk about you, lucy liu, how is 2-year-old rockwell? >> he's great. he's great. he's running around, been to school, very independent. >> comes to the set? >> he comes to the sent. he's at the point now, you know, they're very honest.

good morning. it is 8:57. we are tracking slowdowns for drivers making their way towards the bay bridge toll plaza. it has been a tough day. we are out of the red but in the yellow. we saw some folks head through the toll plaza with reports of a problem just passed the tunnel with a lane blocked. speeds at about 30 miles per hour. passed that, traffic continues to be heavy off at the freemont

exit. at the golden gate bridge, we had problems but lanes are clear in the northbound direction and traffic is flowing freely again but still busy out there. reports of a new accident blocking sfo on ramp to 101. traffic is slow in both directions. let's check in with neda. >> here is a look at the skies now. they are turning grayer out there across the bay. we are feeling a bit of a breeze as well with temperatures in the low 50s for most locations. san jose is at 55 and santa rosa is at 53. the west winds are picking up at the beaches. sfo is at 16 miles per hour, and downtown san francisco at 18, gusts around 30 to 35 over the water. we will continue to see that for the afternoon with temperatures cooler an average. the ridge of high pressure out there will bring us sunshine and warmer weather by the middle of this week and we will be back to above normal.
