emerged from a marathon ukraine peace talk but announcing a new cease-fire deal. putin says the cease-fire will start at 12:01 sunday morning. more than 5,300 people died since the fighting between ukrainian forces and rebels began in april. later today, president obama will sign legislation to help end the epidemic of veterans' suicides. the new law creating a transition program for service members leaving active daty named for clay hunt. a marine who suffered post-traumatic stress disorder. he killed himself in 2011. in the american sniper murder trial today a texas ranger will testifying. he says it's man accused of killing chris kyle confessed to him. nbc's jacob rascon is in texas right now and tell it's us about the emotional first day on the stand. >> reporter: taya kyle fought back tears almost immediately

after taking the stand. the widow of american sniper chris kyle wore his old dog tags and a cross around her neck clutching them at times looking skyward at others. describing the last time she saw her husband alive, she said "we said we loved each other and gave each other a kiss and a hug, like we always did." >> okay thank you. >> reporter: the movie "american sniper" depict it's kyle coping with post-traumatic stress by helping other struggling veterans. in court we learned kyle and chad littlefield took a 90-mile trip to the gun range many times with many struggling veterans. that day they took former marine eddie ray routh, but on the way kyle texted lilfield "this dude is straight up nuts." littlefield responded, "he's right behind you. watch my back." >> taya called her husband right before he died. "i could tell something was up" taya said. "he was just quiet". >> when he took their lives, he

was in the grip of a psychosis. >> reporter: warren told the jury in that moment routh feared for this life. >> because in his psychosis he was thinking they were going to take his. >> reporter: district attorney alan nash. >> but he admits that he murdered these two men, that he used drugs and alcohol that morning. and that he knew what he was doing was wrong. >> reporter: nash said routh shot kyle and littlefield in the back in the face and elsewhere. a total of 13 rounds using two handguns. also among the first witnesses, littlefield's mother who told the jury she was testifying on what would have been her son's 38th birthday. >> that was jacob rascon reporting. right now you're looking at a live picture of a house committee hearing on the growing threat from isis. lawmakers are discussing president obama's request for

war power authority to defeat the terror group. the request is already creating division on the hill. republicans have concerns the request is who limited, yet democrats say the language could be too vague. mr. obama has said however she confident he will have bipartisan support and said bluntly yesterday, "isil is going to lose." will president obama make good on his threat to veto the keystone pipeline bill? we'll know soon i guess. the bill cleared the house yesterday. once it hits the president's desk he has ten days to issue a veto. the bill authorizes construction of the. iline which republicans say will create jobs. however, opponents are concerned about environmental impacts. passing the bill is seen as a legislative victory for republicans, but they don't have enough votes to override a veto. the keystone bill did, however, get support of some democrats in the vote. for more on that we're joined by carrie dann political righter for nbc news. >> good morning.

>> 29 voted in favor. will the president take that into consideration deciding what he's going to do? >> the president has been pretty firm throughout the last maybe month, saying he is going to veto this measure, and the reason they're citing that the pous white house is saying this they say we're still conducting a review what the impact the keystone pipeline would have and by the way, says it's not really congress' job to do this. the president should have the ability to approve or disapprove of this project. we'll see vote oh in the coming days i think. >> he's been saying it for months. i guess we should expect that. >> he'll have ten days. not sure on the timeline but probably within the next two weeks. >> talk about a new poll from a university finds that virginia likes hillary clinton more than any of the republican candidates out there. i guess jeb bush is the only one whose name comes up. tell us about that. >> not too surprising in the sense this is what we're seeing in national polls and key early states like iowa and new

hampshire. you're seeing hillary clinton generally beating out general election candidates right now and jeb bush doing pretty well. depends on the state, but i think this early in this process, jeb bush and hillary clinton are both recognizable names. people feel they know these people and have a good sense who they are. i'm sure we'll see a lot of fluctuation. >> as folks get out there and stump for votes. democrats selected philadelphia. just heard that, the site for their 2016 national convention. why philadelphia? do you think? >> philadelphia was soft the safe choice. democrats narrowed this down both to columbus ohio brooklyn new york or philadelphia. the republicans are actually having their convention also in the state of ohio in cleveland. so democrats might not have -- might not have wanted to double up by choosing columbus. brooklyn it would have been a very different option, but sort of become shorthand for ultra liberal, might have been a concern picking brooklyn. philly hosted the convention before and looks like that's

where we're all heading in 2016. >> yeah. when is the -- do you know the month? september? >> this is going to be earlier, actually. they're going to be in july and back-to-back republicans go first and then democrats the following week. >> all right. a busy time. >> very busy. >> thanks carrie. for more from carrie and the rest of the nbc news political team check out "first read" on nbcnews.com. major announcement on two of the top travel websites and their plans for the future. get this. you can now leave your facebook profile to someone if you die. we'll explain how can you do that. and they are a popular piece of clothing whether you work out or not. we'll tell you why a lawmaker in montana is trying to ban yoga pants. life's morning multitasking.
