Kayla mueller was the latest american to die at the hands of the Islamic State group, and news of her death hit hard. Kaylas calling was to help those who were suffering whether in her hometown of prescott or on the other side of the world. She has done more in her incredible 26 years than many people could imagine doing in their lifetime. Ifill Kayla Muellers parents remained secluded today at their home in prescott, arizona, dispatching friends and family instead, to give voice to their grief. Over the weekend, Islamic State militants sent them unspecified information confirming their daughters death. The 26yearold aid worker had been a hostage since august of 2013, when she was kidnapped leaving a hospital in aleppo syria. On friday, her captors claimed a Jordanian Air strike killed mueller, when it destroyed this building in raqqa, syria. Jordan disputed the claim and today, white house spokesman josh earnest did as well. And the information that we have is that there is no evidence of civilians in the target area prior to the Coalition Strike taking place. And that certainly would call into question the claims that are made by isil. Ifill earnest said u. S. Intelligence has not been able to determine when or how mueller died, but he made clear regardless of the cause theres no doubt who bears the blame. Isil, regardless of her cause of death, is responsible for it. This, after all, is the organization that was holding her against her will. That means they are responsible for her safety and her well being. And they are, therefore, responsible for her death. Ifill and in a statement the president promised action, writing no matter how long it takes, the United States will find and bring to justice the terrorists who are responsible for kaylas captivity and death. Ifill officials said president obama phoned muellers family to convey his condolences. Details of what happened to mueller during her long months of captivity remain murky. But her parents today released a letter they received from her last spring. In it she wrote that she was in a safe location, and unharmed, and said she was remaining strong ifill mueller was the fourth american hostage killed while in Islamic State captivity. Three others, journalists james foley and Steven Sotlof and aid worker peter kassig, were beheaded by the terrorist group last year. Journalist austin tice is still being held in the region, but its unclear who his captors are. In an interview with the web site buzz feed, president obama said, telling families the u. S. Wont pay ransom is as tough as anything i do. Ifill Kayla Muellers death underscores the dilemma the u. S. Is grappling with as it seeks to dismantle the Islamic State. Well turn to president obamas call for new authority to meet that challenge, after the news summary. Woodruff the u. S. Air campaign against Islamic State forces got a boost today, when an arab ally rejoined the fight. The United Arab Emirates launched air strikes against the militants inside syria for the first time in more than a month. Meanwhile, on the bbc, syrian president bashar assad said the u. S. Is keeping him informed about the antiIslamic State air campaign, indirectly. That is through third party. More than one party iraq and other countries. Sometimes they convey message, general message but there is nothing tactical. And is that a continuing dialogue that you have through third parties . There is no dialogue. There is lets say information, but not dialogue. Woodruff president obama has called for assads removal, and at the white house today, a spokesman said the United States is not coordinating our actions with the syrian government, and were not going to. Ifill theres word the u. S. Embassy in yemen is closing amid growing chaos since shiite rebels ousted the proamerican government. It was widely reported today that u. S.

School children and state workers in the boston area had the day off once again, with many roads impassable and most public transport shut down. Massachusetts Governor Charlie Baker warned people theres a new danger, on top of their homes. I really cant believe im saying this, but also people need to think about shoveling off their roofs. Weve had a number of roof collapses over the course of the last several days as the snowfall continues this will continue to be an issue. Ifill state authorities have also allowed snow to be dumped into boston harbor, since theres nowhere else to put it. And, theres more coming.

Woodruff todays announcement of another american killed while in the hands of the Islamic State group puts focus again on whats being done to contain and stop the extremist organization. To that end, the white house is pushing for congressional authorization to use military force. Multiple sources on capitol hill tell the newshour they expect the formal request to arrive tomorrow. For more on what the white house wants and why, and how lawmakers are responding to its efforts to win support, im joined by chief Foreign Affairs correspondent Margaret Warner and newshour Political Editor lisa desjardins. Welcome back to you both. So margaret, why, first of all, is the administration doing this . Theyve been conducting a campaign against the Islamic State for months. Absolutely judy. Theyve been doing it, one to fight al qaeda and number two, to justify the invasion of iraq. But the president has been thinking about this for a long time. He did a speech in may of 2014 in which he said this is too open ended and could be used by any future president to justify enhanced powers that he felt were inappropriate. So, one, its sort of deeply felt by him, but two there are practical reasonsable he wants now bipartisan congressional buyin for both domestic reasons for when he comes in with funding requests and for international reason, to send a message to allies and enemies alike that the American Public is behind this. This isnt just the president going off and doing what he wants here and theyre in for a listening fight. Woodruff what have you been able to learn about the language . Whats in this request . I first have to say, we keep both being warned this could still change before its introduced, but its designed as one democratic said to thread the needle. Because he wants a bipartisan bill, he has to come up with ways to get republican buyin and avoid extremes on either end. So one, there are restrictions on the use of ground forces. It barred enduring offensive ground operations. That was the language as of the middle of the day. A lot of exemptions special force, the advisers and trainers already on the ground in iraq. It would sunset so new future president would have to return for future authorization and it repeals one of the old aulfs the one about going into iraq, but not the one going into iraq. Thats one the democrats wanted to repeal both and the republicans didnt want the repeal either. Woodruff lisa youve been talking to people on capitol hill. What kind of reception will this get she. Margaret says the president has been thinking about this for a long time. Members of congress have been thinking about this a lot for a long time. Theres probably the perception in that the president has sent this up, even though he technically doesnt have to, its an acknowledgement of the power of congress. Thats appreciated obviously in the split power that we have now. However, judy, theres a lot of caution. People want to see the exact wording. Because while you can say that the president has signaled, weve both been hearing from our source, that hes going to restrict Ground Troops in our authorization, the wording matters so much. Thats what members of congress, especially republicans, are waiting to see. Whats interesting overall here is this is a bipartisan plan. It splits both parties. Thats risky or it could be brilliant. Well see what happens with the vote. Woodruff so it is coming down to. Is the boots on the ground language the most important piece of this . Is it the duration of the agreement . What is it that members are a arguing . There are many working parts. The ground troop component is crucial, especially for democrats. That might bring a lot of democrats on if they believe it is a truly firm restriction. If it doesnt he may lose the more liberal wing of the democratic party. But theres Something Else people are talking about. Theyre talking about what are the geographic parameters. What exactly does this limit in terms of geography. The old iraq war powers resolution was specific to iraq for the most part. Well, the Islamic State is something that goes beyond borders. How will the president deal with that in this resolution . So were talking about completely changing our approach to not just iraq but to a much broader territory. Thats why language matters. Tell us about that. Senator kerry last december there was an earlier version of this which i wont get into but he made an impassioned statement in front of the Senate Committee saying no geographic limits. And there are no geographic limits in this. It doesnt mean it will survive because as senator corkers people are saying and senatorrer corker said, as far as were concerned, this is just the starting point. Well have hearings and we want the president to stay engaged. We want him to explain the strategy on syria which both leading democrat tim kaine and senator corker think has not been laid out. And the Administration Knows if they put this forward which they are going to, they cant risk the fiasco that happened back a year and a half ago where he said remember, im going to go to congress for authorization the strike syria and he kind of wimped out and that really damaged the perception of American Leadership in the world. The Administration Knows. Woodruff so it sounds like theyre still sorting this out on the hill. Its not clear where the lines are going to be drawn. Thats right. And i think the white house knows that. Its a slow roll. Tomorrow we know that Senate Republicans are going to meet at 5 00 as a group. That indicates the seriousness of this. There are heavy politics involved here but there is also a sense on capitol hill that this is a very Important National matter. They meet tomorrow, everyone in Congress Goes home next week, and then well see in the following weeks. In general im being told by my sources expect months of debate rather than weeks. Is the white house sounding confident, not sure . Whats your read . Theyre sounding confident their outreach has been successful and hes urged senator jon cornyn, the republican from texas, in fan of the white house, that he appreciated the outreach. So i think that the Congress Knows that the president is taking them seriously and the white house is putting a lot of stock in that. But from talking to people on the hill, i think theyll have a lot to explain and a lot to answer for when they get there and testify. He needs 60 votes. Tough. Woodruff its not 51. Assuming it does come out tomorrow, we will certainly be looking at it in greater length tomorrow. Lisa desjardins, margaret Margaret Warner, thank you both. My pleasure. Thank you. Ifill we turn now to nigeria, and the hundreds of schoolgirls kidnapped last year by boko haram. Despite the global outcry over their disappearance, there are few signs they are ever coming back. And as Jonathan Miller of independent Television News reports from abuja, many in the country have lost interest in their fate. Reporter in a nation where jawdropping scandals make front page headlines day after day there is one that does not. But day after day, every day the bring back our Girls Campaign meets in abuja. Their protest at times has the feel of a wake, but no one has told them whether, after more than 300 days, those whom they mourn are dead or alive. The government of president Goodluck Jonathan has promised again and again to bring the girls back, but the Nigerian Army has failed to bring back even one. Nigeria and nigerians have moved on. This video was posted last may by boko haram, one month after theyd kidnapped more than 200 teenaged girls from a school in the small town of chibok. The insurgent leader said theyd be sold into slavery. Nothing has been heard of them since. Even the starstudded global hashtag bring back our Girls Campaign has pretty much fizzled and died. Its actually very moving to be here. In this country of 200 Million People, this handful of people turns out every single day to remember the missing chibok girls. The Education Minister doesnt even reply to their letters. They say if they didnt come here like this every day, the girls would be completely forgotten. We need to know where these girls are. We need to we really need to. You know for me the greatest pain is that i dont feel my government did the best that it could do for these girls. The regret that i have in my spirit concerning that failure is so profound. Just the thought that this is this is because they are poor, it makes me even angrier, because education is what enables you to conquer poverty.
