Top aides telling nbc on trying to galvanize a key part of the base, women voters. Even bringing former Miss UniverseAlicia Machado to the rally today. Describing how she was insulted by trump. He says to me, miss piggy, miss housekeeping. Its really clear here that he does not respect woman. He has spent a lot of time, demeaning, degrading, insulting uncertainty over the email fallout. 26 of independents in one survey saying it makes them less likely to vote for clinton. And top aide huma abedin, again out of sight today. Her lawyers saying she doesnt know whats on that laptop. As clintons husband and other supporters spent another day going after the fbi director. People who do this for a living have evaluated these charges and found them falling flat. You dont announce and say, we have an investigatioay there, oh, maybe theres not, but well let you know in a few weeks or so. Reporter in battleground florida, the race is tight, with Trump Supporters showing up at clintons rally. Gone is clintons hope of closing with a positive message, at least for now. The campaign strategy, to counteract the email scandal by staying on the attack. Andrea mitchell, nbc news, sanford, florida. Reporter this is katy tur. We cant trust any more than we can trust her with classified information. Reporter donald trump and running mate mike pence, hoping to bring republicans home. I will ask congress to convene a special session so we can repeal and replace. Reporter and gain ground with their opposition to obamacare. The case has never been stronger for repeal. Reporter operatives Say Team Trump has a golden opportunity, a chance for a triple play, tagging clinton on the revival of the fbi investigation into her email server. The allegations cnn contributor and current dnc chair, donna brazil gave clinton questions before a cnn debate, and the rise of obamacare premiums. Rigged system themes that play into their change narrative. They will say anything and do anything, and cling to their power and prestige at your expense. Reporter today the Campaign Announced a 25 million ad buy, a closing message in 13 states. 12 of which president obama won in 2012. The goal, to convince listening to the voices in their head. Theyre listening to what their agenda item might be and ignoring the actual data on the ground. And thats always dangerous. Reporter but more hurdles. A glaring snub from paul ryan, the leader of the republican party, who is still not campaigning with trump, even in his home state of wisconsin tonight. Though ryan says he did vote, he didnt even say Donald Trumps name. Im supporting our entire republican ticket. Reporter john kasich wrote in john mccain for president , underscoring a risk in rift in the gop that even disdain for Hillary Clinton cant mend. Outside of philadelphia today donald trump said hed replace obamacare with accounts. A though he said he would call a special session of congress to repeal it, thats not as easy as it sounds. Even if democrats do lose the senate, its likely theyll still have enough votes to block that legislation. Lester . All right, katy tur tonight, thank you. We want to bring in our Justice Williams in washington. Pete, whats the latest youre hearing from your sources on the status of the review of those emails . Well, despite a roundtheclock effort, they say investigators are nowhere near being finished analyzing the emails found on neath wieners laptop. A senior official says the work is going smoothly, no technical problems, but that progress is slow. Theres no answer yet to one big question. How many of the e of the tens of thousands already checked by the fbi in investigating the clinton email server. Fbi director james comey and attorney general Loretta Lynch had a brief private meeting yesterday. Justice Officials Say both agreed on the need to move quickly to get the email work done. A senior official tonight says theres just no way to tell how long this is going to take, no progress bar at the bottom of the computer screen. They say its impossible to know whether well have answers by election day. Lester . One week until this campaign is finally over, it all comes down to the map and mining the 270 Electoral College votes needed to win. After a series of october surprises, the picture is in flux, as we hit the november home stretch. Where do things stand right now . No one better to ask than our political director, the moderator of meet the press, chuck todd. Chuck, lay it out for us. A week ago, we were talking about a potential democratic wave. But with the fbi investigation reug nighted, its possible that clintons path to 270 has narrowed. This was the map before the fbi announcement. Clinton looked to be over 270. Now, let me walk you through it. The tossup state is nevada. After that, everything is moving from her column to tossup. North carolina, new hampshire, cloird, wisconsin, seem to be the states that have moved into tossup. Look what that does. She needs now a path to 270. Trump meanwhile feels good about georgia, arizona, and utah, theres a path for him. Florida, north carolina, ohio, and iowa. Look where that would put him, 259. He still needs another state. I dont buy colorado for him. Thats still in the blue column. He still needs to break through the big blue wall of the midwest. Michigan, pennsylvania seem out of reach. Wisconsin may be out of reach too, but without it, he doesnt have a path. With it, he could get to 270, lester. Thank you, chuck todd.

A hacking alert tonight, concerning Software Giant microsoft. Intelligence sources tell nbc news, hackers previously linked to the russian government windows operating system for cyber attacks. The same group u. S. Intelligence believes is responsible for hacking the Democratic National committee. As nbc news Senior Investigative correspondent, cynthia mcfadden, explains, microsoft has been in the kremlins crosshairs for quite some time now. . . Reporter over the last several months, Vladimir Putin has engaged in a series of provocative moves, according to the u. S. Government, from nuclear sabrerattling. Relations between russia and the u. S. Are at a low point. I think were at the lowest ebb since the end of the cold war in terms of our relations with russia. Putin is an old kgb officer who views the world as a zerosum game. Between russia and the United States. Whatever is good for the United States is bad for russia and vice versa. Reporter and now russia is opening up a new front going after american companies. Tells nbc news that Vladimir Putin is specifically targeting Software Giant microsoft. Why . Not only because they are the most prominent American Company in the i. T. Space, but they are also known to the russian people and businesses as an easily understood collaborator with u. S. Intelligence. In a statement to nbc news, microsoft says, we dont spy on anyone. We dont work with any government to spy on others, and we never would. But ti to rid the country of all foreign software, in both the government and in statecontrolled companies. And its already begun. With the moscow City Government weaning itself off microsoft, to be replaced by russian products. If putin gets his way, Microsoft Office and windows will be banned. Its a signal that the russians really mean business now about nationalizing the internet and making sure they can reporter the russians are fully aware that microsoft products, like all software, can be used as weapons in cyber warfare. Just before christmas last year, according to a sensitive u. S. Homeland security document, obtained by nbc news, the russians used Microsoft Office attachments to shut down the ukraine electrical grid. The kind of thing russia is worried about the u. S. Having the ability to do to them. To further make their point, last week the russians also banned linkedin, the social is in the process of buying. This may also feed into russian hostility or paranoia towards america and its products. So part economic message, part shot across the bow, part attack on american i. T. , part protectionism, but all, i think, very consistent with the kind of escalation were seeing from putin. So far, putins actions are not affecting microsofts bottom line. In the last couple of weeks, microsoft stock peaked at an all time high. Lester . Tonight, marijuana on the ballot. The legal pot industry hoping for big wins on election night.
