Workers, and it is also good for business. Nightly news begins right now. Good evening. Key dates have come and gone. The next one tomorrow night when democratic president ial candidates face off in the first debate and still no word from joe biden whether he is in or out. But we can report there is a change in a tone of those urging him to run. The wait for an answer is starting that wear their with the top supporters and fraying hopes along with it. Nbcs Kristen Welker has been keeping close tabs on camp biden. Reporter its a waiting game for mothers outside of Vice President s home and joe biden finally emerged late this afternoon but headed for a nearby golf course and still not tipping his hand about a president ial bid. Beyond what he told our producer this weekend. Mr. Vice president , what everybody wants to know. Reporter tonight, the tone is changing among some of his staunchest supporters that are not thinking he will get into the race. Thank you very much. No, i didnt say that. Reporter one of the organizers of his super pac draft biden told nbc news today, it seems like everyone is taking a step back to give him space. Fueling that sentiment is his decision to miss the first democratic debate for tomorrow in vegas where a podium is prepared in case he makes a lastminute decision. The longer he holds off on making a decision, the harder it is for him to offer a formidable challenge to Hillary Clinton. Reporter the latest polls shows clinton leads Bernie Sanders by 19 points without biden in the ratece. And supporters urge him to get in but there are also benefits to waiting. He can assess Hillary Clinton and his ability to weather the email controversy and her testimony to the Benghazi Committee in just ten days. The debate could indicate an opening for him. If she performed poorly and other candidates perform poorly, there is an opening there as well. Reporter now if biden gets in, he has a lot of catching up to do. He hasnt raised any money. Clinton and sanders have raised 115 million combined. He hasnt signed up for primaries and caucuses and deadlines are looming. But hes wanted to be president for a long time and sources say he believes this is his last shot. Lester. Kristen, thanks. And as Hillary Clinton prepares for the first big showdown there are explosive new allegations against the republican Led Committee investigating benghazi. A fired investigator is going public saying Hillary Clinton is being unfairly targeted. And nbc news has learned that investigator is now accusing the powerful congressman leading the committee of breaking the law. Nbcs Andrea Mitchell has late details. Reporter after months of being pounded by the republicanled Benghazi Committee, Hillary Clinton got a potential life line. A former Committee Investigator, a republican Intelligence Analyst told cnn he was fired in part for refusing to go after clinton politically. This has become a partisan investigation. It is a damn lie an that is not a word that i often use. The chairman trey gowdy talked to nbc news exclusively. It was a loudy employee and he mishandled classified information and wont do what his supervisors instructed him to do. In response this afternoon lawyers for the fired Committee Investigator tell msnbc he violated laws by talking about a confidential employment dispute. The Committee Said that is ludicrous. The committee was already under fire after majority leader Kevin Mccarthys suggestion it was trying to damage clintons campaign. What are her numbers today . Her numbers are dropping. But on the private emails uncovered by the panel, president obama on 60 minutes did not do clinton any favors. As a general proposition, when were in these offices, we have to be more sensitive and stay as far away from the line as possible when it comes to how we handle information, how we handle our own personal data. Reporter and as the candidates prepare to faceoff against each other in the debate here in las vegas tomorrow night, sanders will go after clinton for veering left. Hell say flip flopping on the environment, on wall street reform, on trade. And she could go after him for being too far left to lead the party in the fall. Especially after telling chuck todd on meet the press, he is not a capitalist. Lester. Thank you. Now to a trial in milwaukee, seizing national attention, just as the gun control debate is roaring back into the headlines, a gun store is being sued in a case that could set a widereaching precedent. The plaintiffs are two men who protect and serve wounded in the line of duty. Kevin tibbles has the story. Reporter two Police Officers, both shot in the face after stopping a young man for riding a bike on a milwaukee sidewalk in 2009. I thought i was going to die. And i wanted my family to know that i loved them. Now Police OfficerBrian Norberg and former officer graham kunnish are suing the owners of badger guns, charging its negligence allowed the shooter to buy a firearm he should not have had. Surveillance video from inside the shop shows jacob cullins purchasing a gun for the shooter. 18yearold julius burton, too young to buy a gun. It is called a straw purchase. To avoid a background check, the actual buyer has someone else buy it on their behalf. They were shot and injured in the line of duty. Reporter lawyers for the Police Officers say conflicting information on the purchase documents collins filled out should have been a red flag for the salesman. In the store, the atf has tried to shut down in the past. The name has changed several times but it has been run by the same family. Authorities called it the number one crime gun dealer in america in 2005. In 2006, badger outdoors accounted for nearly 500 firearms traced to crimes by milwaukee police. The store, with the second most, had 36. The officers lawyer is asking the juror to award his clients about 9 million in damages. The defendants lawyer argues the owners had no way to know this was a straw purchase. The act of straw purchasing is fundamentally deception. Reporter still those on both sides of the gun issue are watching closely. If the gun dealers lose this case, gun dealers across the country will have to be much more cautious in selling guns. This is a case that will have implications far beyond milwaukee. Reporter the jury will resume deliberating tomorrow. This is the only second case like this to go to trial since the gun owners and manufacturers were granted immunity by federal law back in 2005. Should the dealers in this case win, it will be seen as a blow to the gun control movement. Lester. Kevin tibbles in milwaukee tonight. Thank you.
