ten years ago, kristen mitchell was killed by her boyfriend. >> the campus community at st. e's will team up with kristen's family to honor here. nbc 10's katy zachry shows us how her memory is helping to save lives. >>> kristen's crusade was started back in 2006 to honor the memory of my daughter. >> reporter: ten years have passed since 21-year-old kristen mitchell was senselessly killed at the hands of her exboyfriend. her father, bill, spent the last decade traveling to college campuses to spread the word about dating violence. >> maybe they'll hear some of the things that have taken place and think about their own relationships with somebody who they care about but maybe they're in a tough relationship and don't even realize it. >> reporter: mitchell says kristen tried to break up the relationship when she was stabbed to death. she just graduated from philadelphia's st. joseph's university and had a promising life ahead. for sophomore madison shields, the story hits home. she's witnessed unhealthy relationships and won't hesitate to get a friend or classmate help. >> i'd

and then with me here in philadelphia, andrea mitchell, kristen welker and kasie hunt.ut let's kick it off with katy tur outside trump tower. katy, obviously, on one hand, tonight could be a big night for trump, but i got to ask you a secondary story. because it's primary day, it hasn't gotten a lot of attention. who is running the trump campaign? and i feel like i can't believe i'm asking this late in the process again. >> reporter: i feel like that changes from day to day. there's this internal struggle that we've been reporting on for a couple weeks now between cory lewandowski who is trump's campaign manager and paul manafort who is his convention manager. a few weeks ago, it was paul manafort running things, and we saw that by trump not being on the sunday shows lately, also cleaning up his act a little bit on the campaign trail, starting to sound like he was tighter when it came to his stump speechings, hspeech in s, he's still doing the talking points to a degree, but now there's all this talk that cory lewandowski is getting more power because donald trump was c

. >> kristen welker on the clinton beat. andrea mitchell. let's go with the point that rachel just -- i wasn't going to start there. sanders concede? it's the closest thing to a concession that we might get out of bernie sanders. >> remarkably it comes out a few hours after they sent out a fundraising e-mail that attacked her, called her a traitor for the way she's been campaigning against him and showed a picture of the clintons all smiley, smiley with the trumps at the trump wedding. that's one of the roughest e-mails that they've sent out this entire campaign. so there's sort of a ying and yang of this campaign. i think cooler heads have prevailed tonight. the fact is they're not dropping out. he's going to be in it until june 14th. it is for all intents and purposes over. he will fight for the platform. he said he will be better against donald trump. he has the independents, the young people. she gave a general election speech. she congratulated sanders about what he said about wall street, campaign finance reform and then went after don

mitchell reports." tomorrow we have a big day. we'll be live in brooklyn with clinton supporter u.s. senator kristen jill brand.f the msnbc town halls with john kasich and ted cruz starting tomorrow night at 7:00 p.m. eastern. remember, follow our show online, on facebook and on twitter @mitchellreports. craig melvin is live next up state new york on msnbc, the place for politics. what a beautiful shot. before i had the shooting, burning of diabetic nerve pain, these feet learned the horn from my dad and played gigs from new york to miami. but i couldn't bear my diabetic nerve pain any longer. so i talked to my doctor and he preribed lyrica. lyrica may cause serious allergic reactions or suicidal thoughts or actions. tell your doctor right away if you have these, new or worsening depression, or unusual changes in mood or behavior. or swelling, trouble breathing, rash, hives, blisters, muscle pain with fever, tired feeling or blurry vision. common side effects are dizziness, sleepiness, weight gain and swelling of hands, legs, and feet. don't drink alcohol while taking lyrica. don't drive or use machinery until

kristen welker in brooklyn new york, again the site of that big democratic debate. we will preview that debate in just a minute. >>> first joined by nbc's andrea mitchell, she is the host of andrea mitchell reports here on msnbc. following up on that the connection is interesting. paul song who made the statement, his wife lisa ling, the connection between her, her family and bill clinton. can you explain that. >> lisa ling is a clinton supporter and bill clinton in 2009 helped rescue her and another one of her colleagues from pyongyang have a north korea prison, the former president when hillary clinton was secretary of state. it was a top secret mission done at the behest of the president. that said, this comment no matter what doctor song says about who he meant or did not mean it's very clear from the context from the sentence where he twice references clinton and from talking about democratic whore beholden to pharma and other corporate interests, which is exactly the attack line that sanders uses in his stump speech against hillary clinton. there is no doubt who he meant by that and it does indicate just how nasty this campaign has gotten. that said, tonight's de

kristen, thank you. that does it for this hour of "msnbc live." thank you so much for joining us all week long. we'll see you on monday. up next, "andrea mitchellwhales." for them, nothing else is acceptable. but nothing could be worse for the whales. most of the orcas at seaworld were born here. sending them into the wild wouldn't be noble. it could be fatal. when they freed keiko, the killer whale of movie fame, the effort was a failure and he perished. but we also understand that times have changed. today, people are concerned about the world's largest animals like never before. so we too must change. that's why the orcas in our care will be the last generation at seaworld. there will be no more breeding. we'ralso phasing out orca theatrical shows. they'll continue to receive the highest standard of care available anywhere. and guests can come to see them simply being their majestic selves. inspiring the next generation of people to love them as you do. ♪ everything kids touch during cold and flseason sticks with them. make sure the germs they bring home don't stick around. use clorox disinfecting products. because no one kills germs better

kristen dahlgren, good to see you. >> thank you. >>> the trump campaign did the media rounds today defending their campaign's rhetoric about the delegate fight. here is ben carson who spoke with my colleague andrea mitchell. >> it's really about the american people and whether or not they're being disenfranchised by a bunch of people who sit around creating arbitrary rules. during the jim crow era, those were the rules, too. didn't make them right, and i'm not saying this is the same, but i think you get the point. just because rules are there, just because they're written by somebody doesn't mean that they're right. >> for more now we're joined by politico's ken volo. donald trump is leaving the rnc behind to go after ted cruz. certainly the disenfranchisement, he says, is working. is it effective, and if so, how? >> i think they're both effective. it shows the significant weakness of his excampaign, his disorganization of fighting this battle state-by-state and making it a strength. look, it's the powers that be again trying to deprive me, and you, my supporters, of what we have earned. it also underlines a key rationale for ted cruz's campaign. ted cruz has long casted himself as the outsider, the out
