and then apparently he turned and i heard the door chime. >> more of her harrowing account about what happened that night and how she has spent the years since then. tune into my interview tomorrow morning on "today." peter alexander picks things up next. we begin this hour of "msnbc live" with new information in the orlando shooting. fbi director james comey is in orlando as investigators analyze the latest leads at this hour, including news that shooter omar mateen sold his property to his sister just two months ago. the significance of that we're going to get into right now. our correspondents have been working their sources on these new developments. we begin in washington with pete williams and port st. lucie.

>> i don't know if it is important new information or not frankly, peter. i think this has been overlooked in the week since the shooting. this is something that our investigative people came across the sunday of the shooting because florida has a very open policy about its records. didn't get much information at the time, but let's go back and talk about it a little bit. it was on april 5th that mateen basically transferred the ownership of his apartment to his sister, sabrina, and her husband. was basically a transfer of property, what lawyers would call a quick claim deed. we don't know he did it. it's interesting. does it mean, for example -- and this is what porauthorities are

trying to figure out too. does it mean april 5th, more than two months before the shooting, he was already starting to think about this? i wouldn't have been necessary, of course, because if he and his wife owned the apartment jointly and they were married in california, maybe they were thinking about the fact they were married in an islamic ceremony and there was a question about the legal recognition of the marriage in florida. in any event, even if he was thinking he was going to do something violent and could be killed and he wanted to make sure that the property was taken care of, his wife would have still owned it as his survivor. perhaps there were financial reasons it was transferred. we don't know the answer. investigators don't know the answer. it's just a fact out there. it's interesting to note, but does that tell us much? too soon to tell. >> one more piece as they try to find the back story that led up to the shooting that took place.

ayman, you're near the home of the shooter's father. you spoke to someone close to omar mateen's wife. what are you hearing from them today? >> reporter: well, the source that is close to noor salman has been trying to put together information that portray her as an accomplice. they say she's very innocent in all of this. pieces of information came out that she was with her husband, for example, when he purchased some ammunition, that she drove him by the nightclub to case out pulse before the shooting. the family is saying that is not entirely accurate. she said she went with her husband to a walmart to shop and when they went into the walmart he went off to buy the ammunition. she went off to buy things for

her son. on the way out, she asked him what he bought and saw the ammunition. she asked him why he bought the ammunition. he said it was to help him renew his license. this to say that she's being portrayed in a way that they don't think is accurate, that some of this information is true, but out of context. we've been trying to reach her to verify some of this information as to why her and her husband decided to off load that apartment to his sister. we haven't got a response on that. we've been trying to reach the father of omar mateen to see if he was aware of any of that information. that, too, has not been success. >> omar mateen's father in the last few hours said he was done

talking about this. we're also learning new information over the last 24 hours, ayman, that want to dig into with you about the back story behind mateen, the issues that were noticed by not just classmates, but teachers dating back to elementary school. what more do we know about what might have been very early warning signs? >> reporter: yeah, local officials here have released, i guess, school reports about mateen as he was growing up. they go all the way back to the third grade and even in some of those early notices there were comments of alarm, you could say. things that would describe him as aggressive, rude. he would often make sexual comments. that was not just in the beginning of his adult life. it goes back all the way to third grade, fifth grade, and high school. in high school, he was suspended for 48 days for getting into a

fight with another teen. it was something he said he learned from. when you take some of those early records from his earlier years, plus what we have learned in the run up to his final years, if you will, from his ex-wife saying he was abusive, that he hit her, that he was mentally unstable, his colleagues that said he would have outbursts, when you juxtapose all of those together, you see a consistent timeline of mental instability and aggressiveness that would help shed light on who he was before this attack. >> so many schools where teachers and administrators are trying to see if they see warning signs in their own students right now. we're waiting to hear the obama administration's official response to what is an internal state department memo critici

criticizing u.s. policy in syria. the state department briefing is expected to begin in the next few minutes. we're keeping a close eye on that. 51 diplomatic staffers signed this memo that called on the president to step up america's military involvement in syria. the goal in short to remove syrian president bashar al assad from power. secretary of state john kerry says he welcomes the criticism. >> i think it is an important statement and i respect the process very, very much. i'll probably meet with people to talk when i get back. >> richard engel is in istanbul right now. what change that led to these individuals to speak out so publicly? >> 400,000 people have died now in the conflict.

we're talking about a massive wound in the international community. i think the people at state department are worried about their conscious. they want to make a moral stand saying what is happening right now is not stopping the bloodshed. instead what they see is a policy is, if anything, appeasing assad, that is narr narrownarro narrowly focused on fighting against isis, utilizing a few allies on the ground, like the kurds and the iraq army in baghdad, to fight against isis while not putting pressure on assad, who is being backed by moscow. if you read the reports of this dissenting memo, it wasn't just

to replace him. it was to threaten to bomb assad so he at least takes the u.s. more seriously, that the u.s. policy seems more credible. and if you read the descriptions of this dissenting opinion, it was that the u.s. is allowing assad and moscow to walk over what had been an established policy that assad needs to come to sort of diplomatic solution, cannot continue to bomb cities the way he has been with moscow's help. >> obviously, president obama, who had drawn that red line, and has shown significant reluctance to doing anything more in syria has been the end of the road for these calls for change there. the iraqis, richard, have said they have taken back key parts of fallujah right now. that's isis' longest held base. is this a sign that isis is on its heels finally in some form

in iraq? >> in parts of iraq. the iraqi prime minister said a short time ago said most of the city of fallujah, which is west of baghdad, has been taken over by iraqi forces. iraqi forces were seen on television raising a flag in the center of the city. there were still isis pockets in fallujah, but they have effectively been surrounded with shiite militias and sunni militi militias. it is a significant loss for isis. there is no doubt. it is a symbolic lost. fallujah was also the place with a hundred americans lost their lives two years ago in two major offensives in the city. it has long been a symbol of

sunni resistance, of islamic sunni extremism. losing fallujah is a major blow to isis, but they still have mosul and raqqah. this is not the end of the road. >> richard, thank you very much. joining us now on the same topic is mark ginsburg. he is the former white house middle east policy adviser. ambassador ginsburg, nice to see you. 51 u.s. diplomats signing this dissent memo to change policy when it comes to air strikes, frankly whatever they would do going forward in syria. does it surprise you to see this behind-the-scenes dissent come out like this? >> i'm surprised it took so long, peter. you cannot underestimate the importance of this dissension. i've worked in the state department on and off for 16 years. 51 diplomats condemning the policy of the administration, including by the secretary of

state, mr. kerry himself, cannot absolve himself of the responsibility of having his subordinates take him on in their dissension. this is very unusual. most of the key syrian diplomats that the americans had in damascus, former ambassador ford and others, they're the ones that have been the most vocal critics of administration policy ever since the civil war began in 2011. >> and one thing that is striking is you can see the different groups fighting for their own interests in that region right now. the question is whether the president's plan to exclusively use diplomacy to end this civil war would work. a lot of the fighting groups are note participants in those talks right now. >> well, indeed. and i don't think that it's something we can draw the conclusion that what diplomats are doing are calling for more boots on the ground in syria.

the frustration level is, one, both the russians and the assad regime consider that they have license now to attack u.s.-backed rebels without any consequences from the united states. number two, the united nations broke its cease fire that secretary kerry touted so much. assad is stronger than he was before. number three, the concept of creating a safe haven in northern syria in order to stem the flow of migrants had been so categorically rejected by the white house and supported by mrs. clinton is evidence that underneath the brush here there is significant disagreements between the obama administration and mrs. clinton over what to do with syria. many of these diplomats supported her in her efforts and were rejected by the white house security council. >> seven months left in the obama administration. the likelihood that anything does change in that time with the new president waiting in the

wings is what? >> i don't think very much. i think the administration is going to focus its efforts on isis and has conceded the fact that assad is going to remain in power. >> that may be the biggest takeaway. nice to see you. thank you very much. >> thank you, peter. is he in? is he out? growing signs that senator marco rubio may run to keep his senate seat afterall. we're going to take it to capitol hill live for the very latest next. this company's servers. accessible by thousands of suppliers and employees globally. but with cyber threats on the rise, mary's data could be under attack. with the help of at&t, and securityhat senses and mitigates cyber threats, their crital data is safer than ever. giving them the agilto be open & secure. because no o knows & like at&t.

i take very seriously everything what's going on, not just in orlando, but in our country. i have enjoyed my service here a lot. i'll go home later this week and i'll have some time with my family. then if there's been a change in our status, i'll be sure to let everyone know. >> a source close to senator marco rubio telling politico,

quote, a number of dominos would have to fall before rubio reverses course and runs to defend his seat in the senate. it seems at least one more domino has fallen. congressman david jolly dropping his bid to replace rubio. rubio's team is reportedly also laying the groundwork for a run, telling the political network to be prepared. luke rossert is on capitol hill with more. some thought this weekend. he has been pretty clear about the fact he's never really been a big fan of his ability to effect real change in the senate. how close is he to a new decision? what are his chances? where do things stand right now? >> the expectation is that marco rubio will run. now, that's not a definite, but that is what his colleagues and

the republican caucus there believe, especially roger wicker, who is the chairman who is responsible for getting republicans elected to the senate. there's a few others who have said if rubio gets in they would seriously reconsider their own bids. marco rubio is a very famous politics in terms of name rec. his pathway to get re-elected is not that easy. donald trump is a difficulty, not to mention the advertising the democrats can do about marco rubio not liking the senate and all the votes he missed. he would face a challenge from a businessman democrat who has raised a fair amount of money and is well liked by folks across the state. >> how did this change so rapidly? >> i think what folks have said is a combination of factors. one, he believes if he were to be removed from the conversation

entirely, if he were to go into the private sector and just make money, he would not have the bully pulpit that can be effectively used to run for president again. the orlando massacre perhaps switched up his thinking. i've got to repeat it's a huge gamble. if he loses, his political career is all but over, peter. >> he saw a lot of vulnerability exposed in that florida primary against donald trump not too many months ago. thanks a lot. as the nation mourns the victims of the orlando tragedy, we're remembering the nine parishioners that were killed a year ago today in charleston, south carolina. the front page reads our city mourned and found unity in tragedy. that unity on display today at a memorial service for the victims. we are outside emanuel ame

church with more. i can only imagine the emotions obviously on a day just like this. just such an awful anniversary as they try to celebrate the lives and mourn such a terrible loss. what was that memorial like today? >> well, it was a beautiful three-hour ceremony that wrapped about 1:00 eastern time. you mentioned that word a lot of people want to be the lasting legacy of this awful event and that's unity. having these folks who may have differences of opinion come together on racial lines and get rid of some of the old images of the past, if you will. that is the point they're trying to make going forward with all the events surrounding this anniversary. governor nikki haley was one of the many speakers who spoke today. you'll remember one of the family members famously forgave this alleged shooter during his first court appearance. not everyone is quite at that point yet. >> please don't forget the families. for them, the hurt is not over.

don't forget the survivors. many of these family members and survivors still feel lost and still feel broken and every day is struggle. pray for them. try and do what you can for them. let them know they are still loved because anniversaries don't mean anything to them. they're living this each and every day. it is our job as a people to prove to them that june 17th was not in vain. >> all right. now at 4:00 eastern time there is going to be a service here at mother emanuel that will go for a few hours. at the end of this ceremony, they're going to have a mixer to keep people talking through their differences so this community comes together more so than it was the night of that horrible activity in the

basement of emanuel church back in 2015. peter? >> thank you very much. president obama's top lawyer talks exclusively to msnbc about donald trump's proposed muslim ban and what would happen if it ever made it to the supreme court. our ari melber breaking it down. an exclusive conversation that is coming up next. ♪ ♪ ♪ take on the unexpected with a car that could stop for you. available in the altima, sentra and maxima., be the you who doesn't cover ur moderate to severe plaque psoriasis.

donald trump will rally with his supporters tonight in texas. and if the past is any indication, he's going to use one of his go-to campaign promises, that is a temporary ban on muslims entering the u.s. >> and after san bernardino. and it was met with great scorn. we have to stop on a temporary basis, at least, but we have to stop people from pouring into

our country. >> that's become a common refrain for donald trump, but would a ban like this even be constitutional? ari melber is here. give us a sense of what the solicitor general's take is on this topic. >> he argues all the big cases for the obama administration at the court. here's what he said. >> you mention immigration. when people look and say, oh, you've got a nominee proposing a religious ban for immigration. legally, constitutionally, would that power exist? >> i'd be surprised. i'd be surprised to think that it would. >> you think the supreme court would strike that down. >> you don't want to celebraspe on a case that doesn't exist or ever would exist.

>> a religious test is banned itself in the constitution? >> a different context, but yes. >> he is citing a specific part of the constitution that he believe this is court would use to strike it down if ruled upon. the other thing i want to get to is marriage equality. >> his legacy is tied to the president's on this. >> he worked on earlier gay rights cases when they were just trying to get sodomy laws struck down. marriage at this time was thought way out of the ballpark, which we spoke about. i said why does this matter. he talked about the way law and these cases can effect people, including children all around the country. here's what he said. >> having laws forbidding same-sex marriage in a number of states could have an effect on the way kids who were gay and lesbian grew up in those states feeling like there was something wrong with them and the state

didn't support that and having that change i thought was something of profound importance. >> the argument there is part of what he convinced the supreme court to side on is marriage equality is not just about the two people might be in that marriage. it's about the standing of americans who may be of varying sexual orientation to be equal and to be seen as equal. that, he felt, was important. >> thank you very much. >> thanks for having me. >> nice to see you. donald trump on the stump in texas. not exactly a battleground state, of course. why is he there? this trip may be more about campaign cash than about votes. hillary clinton unleashing her sizable cash advantage on her growing opponent with an ad buy aimed at some critical areas in this country. we're going to check in with the campaigns next.

former president george w. bush now diving back into

politics after abstaining for the last aleight years. bush believes it is, quote, critical to try to save his party's most vulnerable senators, including those whose campaigns have become more challenging with donald trump as the presumptive nominee. paul ryan gave republicans license to follow their conscious on trump. >> the last thing i would do is tell anybody to do something that's contrary to their conscious. of course, i wouldn't do that. look, believe me, chuck, i get this. this is a very strange situation. this is a very unique nominee. i feel as a responsible institutionally as a speaker of the house i should not be leading some chasm in the middle of the party. >> according to "the new york times," aides are scrambling to

raise money to compete against hillary clinton and her extensive donor network. there are signs of chaos at the republican convention in cleveland. jacob rascon is in woodlands, texas, today. tell us about this new effort to try to challenge trump at the convention. this one appears to have at least a little bit more traction. >> reporter: effort to derail him at the convention, not new. we have talked about that for months. since he clinched the nomination, they seem to have closed down those calls. now they are insistent they shouldn't be bound by something they call a conscious clause. they want a majority of course on the rules committee to say that they should be able to do that. they know it is a long shot. it is a very last-ditch effort,

of course. we're talking about a month or so away from that. nbc news reached out to the trump campaign who say they're convinced they have an overwhelming majority at this point of delegates on the rule committee. they say there's no chance here for that, but these delegates we're talking to of course believe very differently. >> anticipating donald trump's arrival there this evening. thank you very much. the price tag of hillary clinton's battleground state ad blitz has now skyrocketed. we first reported that the ad buy in eight swing states was at a price tag of about $7 million. we're now told the buy is up to 17 million plus with clinton's biggest investment in the state of ohio. i want to get to kristen welker. give me a sense of the significance of the states that she's choosing to spend money in. i ask you this question against

the backdrop of donald trump spending another 24 hours in texas, a state that should already be off the board for republicans. >> that's right. it's a reliably red state. secretary clinton is targeting these key battleground states, these states that are necessary to win the white house. ohio, north carolina, virginia, colorado, iowa, states that you would think donald trump would be campaigning in. instead he is raising money. a lot of the gop concerned about the fact he's not raising as much money as mitt romney raised at this point, for example. the bulk of the ads are going to be these bio ads, reintroducing secretary clinton to the voters. right now her unfavorable rating at 55%. that's pretty high. donald trump's by the way even

higher. it's at 70%. but it's an acknowledgment by the clinton campaign this is something they need to work on headed into the fall. she's going on offense here. this is what president obama did back in 2012, defined mitt romney during the summer months. it was pretty much cemented when the fall campaign season started. >> it is normally the mind-set when they come back for labor day. i want to talk to you about bernie sanders. he did not concede in what was a video address to his supporters thursday. how does this situation with sanders play out? i'm struck by how much his political capital has shrunk since california. >> i'm not sure senator sanders knows how this is going to play out. when i talked to officials in his campaign, i asked what he does want, what has to happen in order to concede. he wants to feel he has won a

concession from her, something significant, but he is asking for things like getting rid of superdelegates, getting rid of dnc chair debbie wasserman shultz. there's no indication that any of his big demands are going to happen, so how does he land this plane? democrats are giving him some room to maneuver. it took secretary clinton several days to concede to barack obama, but the patience is running out. senator sanders really losing leverage every day. democrats eager for him to get on board, start campaigning with secretary clinton, and start trying to convince of the third of his supporters who say they're not ready to support her. >> nice to see you. thank you. >> you too. >> as clinton blankets the air waves in those crucial states,

the trump campaign is still struggling to get on the same package right now. the rnc has tried to advise the trump campaign on his personnel hires, on his messages, even on his strategy, but the campaign, as america as witnessed, not really following along. joining me now to talk about this is eli stokels. this report by one of your colleagues talks about donald trump's taxes. some new information this afternoon that shows trump may have paid anything in taxes as recently in the 90s. before we knew that to be the case by some reporting in the late 70s. this suggests he may not have paid any taxes in the early 90s. >> 1991 and 1993. it was a similar situation to what happened in the 70s when trump in the real estate

business because of his investment involvement with some casinos had losses that were big enough that they allowed him to pay no income tax. this is all legal. something that obviously trump has shielded as best he can from public view because he hasn't wanted to release any details about his tax history, his tax returns over the years. but this was a person who in 1991 and 1993 didn't pay any federal income tax. again, totally legal, but his creditors had him on allowance of $450,000 a month. he could live on that a month. people will make of that whatever they will. not breaking any law, but a guy who still owned a yacht and a jet into the paying any taxes. trump responded to the story this afternoon in an e-mail back to us. his quote was pretty succint. he said welcome to the real estate business. that was his response. >> i want to talk to you more broadly about the trump campaign. hillary clinton now leading in three of the most recent polls.

donald trump watching his numbers drop. cbs has her up by seven points. bloomberg in double digits now. how lo at the end of the day, really it's organization that matters in a general that you need that money for in places like ohio, california, and virginia that trump says you may not have needed in a primary. >> 17 candidates, a very narrow swath of the electorate. i think that success has made him overconfident. you talk to his campaign and they say, we've done it our way. trump is not going to change anything now. it's a total failure to recognize what is basically politics 101. we're not measuring success based on republican primary voters. the message has to change. the failure to sort of adapt the

message to broaden and professionalize this campaign, it troubles a lot of republicans as does obviously the messaging coming from trump post-orlando, the comments that preceded that about the judge. there's a lot of frustration. the rnc has to publicly say, look, we're on the same page. we're going to win. they're behind on fundraising. every trip he does right now is about fundraising. then they throw a rally on top of it. hillary is campaigning in swing states. donald trump is in texas, georgia, and north carolina. north carolina sort of a swing state, but he is in deeply red states because he is so behind raising money. there is just no campaign infrastructure and organization in a lot of these swing states yet that they're going to need. he says we haven't gotten started yet. we're going to get there, but every day counts. >> one republican strategist telling me it was one thing to

win roughly 14 million votes in a primary. it's another thing to get 60-plus million votes to win a general election. thank you so much. >> thank you. we're learning new details right now about the suspect who allegedly shot and stabbed a british parliament member to death, a murder that has britain reeling just a day later. did he have neogn-nazi ties in e u.s. d like to... cut. thank you, we'll call you. evening, filnoir, smoke, atmosphere... bob... you're a young farmhand and e*trade is your cow. milk it. e*trade is all about seizing opportunity. sign up at etrade.com and get up to six hundred dollars.

parliament will honor cox on monday. a suspect is in custody now and has been named by itv. they say this 52-year-old man is thomas mair. he's suspected of having ties to an american white supremacist group leading to some speculation that cox's pro-immigration views may have inspired the attack. a historic punishment given today as russia's track and field team has officially been barred from competing in this summer's olympic games in the wake of a state-sponsored doping scandal. the track and field's governing body upheld the competition ban saying russia didn't do enough for readmission. this is obviously an

unprecedented punishment laid down on the russians today. is there any new reaction from russia? some may say vladimir putin may say, enough, nobody is going to go. >> it's possible, peter. vladimir putin was lobbying to try to get an opposite decision to this. the ministry in russia is accusing officials here of destroying the dreams of clean russian athletes. talking to members who made the decision, they say they simply felt like they had no choice. here's some of the report. it says there is a deep seeded culture of tolerance or worse for doping in russia. there are detailed allegations already partly substantiated that the sport in russia has in fact orchestrated systematic doping. faced with that profound report, we had no choice but to say the

entire russian track and field team cannot go to rio. >> thank you very much just moments ago, the state department finally commented on a huge story today. about 50 state department officials signing onto a memo demanding u.s. military action against syrian dictator bashar al assad. here's john kirby just moments ago. >> it is unusual for a dissent channel message to have as many signatories as this one. i think it tells us several things. i think it tells us that we have a unique process in place here through which employees at the state department can offer unvarnished views all the way to the top as they desire. i think it tells us clearly that syria matters a lot to the people who work here at the

state department as it should, and i think it says to me that we need to keep on working just as hard as we can for better outcomes, as the secretary and so many others are doing. you should be getting double miles on every purchase! switch...to the capital one venture card. on every purchase, everywhere,ed every day.es not just ...(dismissively) airline purchases. seriously... double miles... everywhere. what's in your wallet? burning of diabetic nerve pa, these feet learned the horn from my dad and played gigs from new york to miami. but i couldn't bear my diabetic nerve pain any longer. so i talked to my doctor and he prescribed lyrica. lyrica may cause serious allergic reactions or suicidal thoughts or actions. tell your doctor right away if you have these, new or worsening depression, or unusual changes in mood or behavior.
