The fbi is investigating whether weiner broke the law. Investigators used the abedin the official also said theres no indication so far that anyone was with holding evidence. Fbi Officials Say comey sent the letter today, out of an abundance of caution and that investigators have no idea whether the email was change his conclusion in july about whether her use of the private email server for classified information was a crime. Our judgment is that no reasonable prosecutor would bring such a case. Unless theres evidence that shows intent or shows with holding. Its hard to see that would be a different result just because there are more classified emails that were sent by the same method. Fbi officials insist tonight the case is not being reopened. They say that the case had not been formally closed, largely because of pending freedom of information act issues. Comey said he felt obligated, though not legally required to send the letter today disclosing this new development after telling congress in july that the investigation of the private server was completed. Lester . And pete of course the campaigns, a lot of voters out. Is there a timetable as to when they might have resolution . No, comey says in the letter he doesnt know. And so far Officials Say investigators have no idea even whether these newly found emails actually contain classified information or not. And its possible some may duplicate what the fbi has already seen but theres absolutely no way it will be done by election day, lester . Pete williams in our Washington News room. As you can imagine, the stunning news sent both the clinton and Trump Campaigns scrambling to the Clinton Campaign now demanding the feds release more information to the public and donald trump down in the polls pouncing on the new developments. We have it covered starting with Nbcs Kristen Welker with the Clinton Campaign in iowa. Whats the word there . Lester, good evening Clinton Campaign officials tell me they learned about the fbis decision from news reports. Stunned, they put the rally into damage control mode and theyre the short statement plays right into republicans hands. Tonight the Clinton Campaign call the fbis director move extraordinary for its timing. It boggles the mind why the step was taken with 11 days to go. The political bombshell hitting before Hillary Clinton even landed for her first event in iowa. On the plane the campaign touting its early voting numbers. The Hillary Coalition is turning out in record levels across the country and overall were seeing very high turnout. But t midflight news that the issue thats haunted clinton for months, her emails was back. Clinton show to get off her Campaign Plane after huddling with staff for 20 minutes and a photo shoot with photographer annie lebowitz. In iowa she rallied her most dedicated supporters women. Weve got work to do. But no mention of the fbis announcement. Clinton responding late tonight. We are 11 days out from perhaps the most important lifetime. Therefore, its imperative that the bureau explain this issue, in question whatever it is, without any delay. Its an issue her team thought she had put behind her. I made a mistake using a private email. Thats for sure. And it comes after a rocky week, days of headlines about hacked emails released by wikileaks, including a 2011 memo where a top aide to bill clinton describes what he called bill clinton, inc. , a strategy for securing millions the former president from Clinton Foundation donors. Clintons team hoping to move that story off the front page, with reports she was looking past election day, considering joe biden to be secretary of state. Although biden tonight saying hes not interested. So could the fbi announcement with a gamechanger . Voters reacting in battleground florida. It is very, very concerning. We, we want to know all the facts. We have to find out whats going on. Its alarming. Friend, he gave Hillary Clinton a clean bill of health. Now he has injected at the last minute major uncertainty into this race. On a day where the clinton Team Appeared upbeat and optimistic at the start. Tonight more somber as they face a big hurdle, kristen welker, nbc news, des moines. This is katie tur covering the Trump Campaign. A reenergized donald trump took the stage in New Hampshire this afternoon. The fbi have discovered new emails secretary of state Hillary Clintons investigation. After weeks down in the polls, todays fbi news came as a shot in the arm to trumps struggling campaign. This is bigger than watergate. Trump, who has called the election rigged, the system corrupt and derided the fbis investigation, suddenly changed his tune. It might not be as rigged as i thought. Right . Regain momentum long saying Anthony Weiner would prove to be a problem for Hillary Clinton. Anthony weiner. Who is a sleaze ball and a pervert. The gop nominee is welcoming the distraction from a slew of headlines questioning his commitment in the final stretch. As the latest s. E. C. Report shows he only contributed 30,000 to his campaign this month. Trumps big cash promise made as recently as this afternoon. Ill probably hav close to or over 100 million of my money spent. On the campaign. So far, falling short. Now trump is saying he gave his campaign 10 million more. Nbc news has learned from Campaign Sources this latest donation is intended for battleground state tv ads. Some muchneeded onair messaging, now with a renewed attack line. I dont know if it will change the race in his favor. It does i think put a pause to clinton. I just spoke to a source close to the campaign who tells me donald trump didnt mention Anthony Weiner at his last event because he wants to keep the focus on this negative headline for Hillary Clinton for a change and not his reaction to it. Well see if that strategy continues into tonight. Lester . Katie tur, thanks. Lets bring in our political director, moderator of meet the press, chuck todd. Chuck, i know were hours into this, but 11 election, what are the potential political ramifications . You see it by watching the reaction and who jumped on this first and there wasnt a republican in washington, there wasnt a republican on the ballot that didnt jump on this news in a hurry. This week alone, i do think we may see this news added to the obamacare news, added to the foundation, all of it, giving republican candidates down the ballot, a closing argument. If it has an impact, what is it . I have to say, i will be surprised if director comey thinks he can just let this sort of meatball hang out there for 11 days without providing more details. This is something that i think is going to bother a lot of voters. Forget you hear partisans on both sides being upset. You throw this out there, but not with a lot of details. What is it . What does it mean . I got to think the fbi cant let this wait until after election. Chuck i know youll have a lot on meet the press on sunday. You know it. Emergency on the runway in chicago.
