BOLDUAN: Any minute now, the Pentagon will release its final report on the ISIS ambush in Niger, which killed four U.S. troops last year. Joining me now for more on this is CNN Pentagon correspondent, Barbara Starr. Barbara, what can you tell us about what the Pentagon is concluding here?</s>BARBARA STARR, CNN PENTAGON CORRESPONDENT: Kate, what we expect in just about 10 minutes is the beginning of a press briefing for reporters. Unfortunately, we will not get the report seven months later. That is expected to be declassified. But we will hear their version of what happened and how they think these four troops got killed last October 4th. One interesting thing is the report concludes that they were on, at least in the beginning, an unauthorized mission, that they were told to go look for a high-value ISIS operative in this corner of Niger. They were not authorized, trained or equipped to do that mission. There were then switched to another mission to advise forces. That's what they were supposed to do from the beginning. They get ambushed by ISIS, which has a 2-1, 3-1 advantage over them. Heavily armed ISIS fighters. During the firefight, the U.S. troops get separated from each other, there is confusion. All of this resulting, obviously, to great tragedy to four American military families who lose their loved ones in this battle. This quite candidly is not supposed to be what happens. U.S. troops are sent out heavily trained, heavily armed and very much disciplined to carry out the mission they're assigned. These young American forces, we are told, fought valiantly right until the end but, sadly, they were not given everything they needed to be successful -- Kate?</s>BOLDUAN: Still so many questions of how it all went down. Thank you, Barbara. Much more to learn here. I really appreciate it. Coming up for us, new polls mean not such great news for Democrats going to midterm elections. What's giving Republicans a big boost right now and what are Democrats going to do about it?
