has been asked about. >> when donald trump said he wasn't going to participate, he said the democratic nominating process is totally rigged. he went on to say, hillary clinton and debbie wasserman schultz will not allow bernie anders to win. do you agree with his characterization? >> i have been very touched by donald trump's love for me. john, in all due respect. i think there may be some -- some aspect of this which he things will advantage himself. so i do appreciate his love and his compassion for me, but i don't really accept his word. look. we knew when we were in this, we were taking on the entire democratic establishment. no secret about that. yet we have won 20 states. in california right now. i think we have a good chance to win here. i think we have an uphill fight. there is just a possibility that we may end up at the end of this nominating process, with more pledged delegates than hillary

clinton. what has upset me. i wouldn't use the word rigged we knew what the rules were. what is really dumb. you have closed primaries in new york state. 3 million people, democrats or republicans could not participate. where you have a situation where over 400 superdelegates came on board clinton's campaign before anybody else in the race. eight months before the first vote was cast. that's not rigged. just a dumb process which has certainly disadvantaged our campaign. >> you are going to try to convince the superdelegates when said and done to go with you instead of hillary clinton. you made a disstin kttitinction. will you not try to convince any superdelegate? >> if i win or hillary clinton

if that is your point. hillary clinton won mississippi by a huge vote. should i convince superdelegate there is to vote for me when she won the state overwhelmingly. no, i shouldn't. but we want states, you know, like washington, alaska, hawaii, new hampshire, in landslide victories. i do believe that the superdelegates. clinton's or mine. states we won. superdelegates where candidate wins a landslide victory should listen to the people in the states. >> president obama will mark memorial day at arlington national cemetery. lay a wreath at the tomb of the unknowns. the president returned to washington this weekend after his trip to asia. it was capped off by a visit to hiroshima, ground zero for the first nuclear bomb attack. foreign affairs correspondent, margaret bren nan was with the president and filed this report. rancheros a poignant moment, an american president embracing victims of the first atom bomb

ever used in war while standing 1200 feet from the epicenter of the blast. 71 years after the attack, president obama decided it was time for a commander-in-chief off to confront his history. >> mere words cannot give voice to such suffering. but we have a shared responsibility to look directly into the eye of history. and ask -- what we must do differently to curb such suffering again. >> white house officials were insistent that this was no apology tour. but the president did reflect on the hundreds of thousands of souls lost as a result of president truman's decision. justified then as a necessary evil to avoid a costly land invasion of japan. the heat of battle its faded from memory, but the images of destruction endure. it was here in hiroshima that death fell from the sky that august morning, ushering in a

global nuclear arms race. while he has broke end significant arms control deals, mr. obama hasn't made much of a dent in america's own nuclear stockpile. reducing it less than any post-cold war president. today, a high tech bustling hiroshima has arisen from the ashes. as the the city has moved on so have japan's leaders. the prime minister abe offered condolences to the american lives lost in world war ii. a tacit acknowledgement that japan first attacked the u.s. at pearl harbor. for president obama, visiting hiroshima, an attempt to bridge a painful divide with a former foe. not the first time, having reap opened long severed ties with cuba, lifted arms embargo and negotiated with iran. when it comes to bearing the remnants of war there is nowhere he could have made his case more powerfully than here.

ammunition that killed all of these folks. and i'm not exactly totally happy that i did that. but at the time, that was my job. i was, i couldn't question that. >> reporter: why now? why important do you think to return the flags now? >> well -- it's a closure. you can't keep hating people. >> reporter: inspired, terry stockdale packed up one of his father's flags and mailed it to the only place he thought could help. a home in a small town along the columbia river in washington. where the flags are celebrated with a ceremony. >> this is not the flag, it is the spirit of the soldier. we are wishing he can find a way to find a family in japan. >> reporter: keiko and red zeke run a nonprofit, obone society. in japan, a festival, honoring

the spirits of ancestors. turned their attic into a make shift flag research center. >> when we started out we thought we were just helping japanese families receive heirlooms. then, as the this progressed we realize weed were connecting these families. >> lots of personal messages. and many signatures. keiko's own grandfather died fighting in the pacific. but his grave is empty. >> no bone, no remaining item, nothing came back. >> reporter: one day his flag did. >> we all thought that that spirit of the grandfather finally wanted to come home to seep us. >> reporter: it had such a profound effect they wanted to see if they could identify more soldiers' flags and send them back to japan. once word got out. they were stunned. flags from veterans or their families started arriving almost weekly. >> some times they include photographs of their father as a

soldier, or family pictures of themselves now, it any just this, it is this, connection of this family to this family that -- that were brought together through war. >> reporter: soap f far reunite flags with japanese families and more than 100 they are all researching. all at their own expense. terry stockdale waited and hoped. then came word that the obone society traced his flag become to a man named yogoshu kishi, a young soldier kissed his wife, 7-month-old son and 2-year-old daughter good-bye and never saw them again. those children, now 73, and his sister, 75, both live outside osaka. they knew little of their father until one day last december the phone rang. >> translator: when i got the call, i thought this was

impossible. my mind just went blank. after 70 years, i never dreamed something of my father's would surface. >> reporter: they found out terry not only had their father's flag, but he wanted to come to japan to deliver it himself. anxious they met terry at the train station. what happened next? says it all. >> i mean, it is just beyond comprehension what it meant to them. it just wasn't some souvenir, it was their father coming home. terry officially handed it over at a formal ceremony. and then stepped back to watch two people who never knew their father, unfurl his flag, together. >> translator: we don't know the

warmth of his hands, the sound of his voice. i can't remember a thing about my father. and i said, i'm sorry dad, to that flag. i'm so sorry. >> it just feels so good to do something for somebody. >> reporter: as for his own father, well, terry hopes that staff sergeant glen stockdale is also finally at peace. there's moving... and there's moving with move free ultra. it has triple-action support for your joints, cartilage and bones. and unlike glucosamine chondroitin, it's all in one tiny pill. move free ultra. get your move on. >> important message for residents age 50 to 85. write down this number now. right now, people are receiving this free information kit for guaranteed acceptance life insurance with a rate lock through the colonial penn program. if you are on a fixed income, learn about affordable whole life insurance that guarantees your rate
