Thank you for joining us. Tonight, high stakes in the biggest Abortion Case in more than two decades. Were inside the very human efforts on both sides of the debate. As many look to make the crucial difference in a legal decision that could impact millions of lives. Heres abcs Gloria Riviera. Reporter separated by just a few feet, but they stand a world apart. Today outside the Supreme Court, passions inflamed on both sides of americas most enduring culture war. While inside, the most important Abortion Case being considered in a generation. Improve patient safety. Thats what these laws have always been about. They are going to make abortion less safe. Reporter arguing that controversial texas law that regulates abortion clinics as unconstitutional is stephanie toady. Its her first time at the nations highest court. But with her, some star power support. I realize the next generation may have less choice than i did. Reporter judging amy and leftovers actress amy breneman and 40 other women lent their name to the cause, saying that having an abortion allowed them to have happier, healthier lives. I was 21.

I feel so blessed that i was in place that i wasnt reshaping it alled shape med and i was supported. If you start delving into your family and friends, youre going a pregnancy. So, therefore, its in everybodys life. And i draw the line for whitney. Reporter believes restrictions around the country are going too far, shes joined forces with other celebrities in the draw the line campaign. Im elizabeth banks, and i draw the line for rebecca. Reporter encouraging women to share their stories about how abortion helped them instead of hurting them. This is not the First Campaign of its kind. I had an abortion last year. It was an incredibly positive experience for me because i didnt want to become a mother. Reporter last year, amelia decided to share her story on facebook. And giving it a hashtag shoutmyabortion, and it went viral. Plenty of people still believe that on some level, if youre a good woman, abortion is a choice that should be accompanied by sadness, shame, or regret. But i have a good heart, and having an abortion made me happy in a totally unqualified way. Reporter she says she was not surprised by the outpouring this country have had an abortion by the age of 45, according to one study. Within a couple of hours, there were women in and out of my Social Circle that were just saying, hey, i had an abortion too. I think the shout your Abortion Campaign is phenomenal. I love it. Reporter they have taken it personally. Look at you Martha Plimpton also shared she had a positive experience. For me in particular, because i did have two abortions as a young woman, i feel that my ability to access that kind of medical care made it possible for me to live out my dreams and do what i really wanted to do with my life. Reporter among other restrictions, the texas law requires that abortion clinics are more like surgical centers, and that doctors have admitting privileges at a hospital within 30 miles. You want to be a health care provider, then act like it. Thats what were saying. Reporter critics of the law say adhering to the new standards make it impossible for especially in a state the size of texas. Millions of women in texas and other states across the region are at risk of losing their constitutional right to access safe abortion care. Reporter millions of women. The Ripple Effect could be huge. Absolutely. We have seen copycat laws in other states in the south. Reporter and since the law was enacted, half of the abortion clinics in texas have closed. What kind of personal stories are you hearing . Stories about women having to travel out of state because the waits for an appointment with an Abortion Provider in texas have become so long. Reporter in a new documentary, trapped, doctors and nurses at whole womens health, one of the texas abortion clinics thats challenging, shares stories about how they had to turn away women in need. Theres a two to threeweek where time is of the essence. I remember getting a call from a patient and said, what if i tell you what i have in my kitchen cabinet, and you tell me what i can do. Reporter but those on the other side of the issue say that the texas law and others like it are designed to protect womens health. Antiabortion activists also submitting briefs to the court, citing 3,000 women who they say suffered grievous psychological injuries after their abortions. A majority of americans, regardless of whether they say they are prolife or pro choice on the issue of abortion, agree that abortion should be safe for women. Reporter Kristen Hawkins is president s for students for life of america and has recruited thousands to the cause. Today we have come out to show the Supreme Court justices that this is a prolife generation. My mission is to abolish abortion. And to make abortion unthinkable and illegal. Reporter she thinks the stricture regulations on nation are just the first step. Were a prolife generation reporter we were with the young mother last year at one of the largest ever antiabortion demonstrations. This is what the Prolife Movement looks like at its strongest in the United States today. Were at the march for life. And what you see behind me goes on for miles. Today i speak to you pregnant with my fourth child. My first daughter. We are the prolife generation reporter to some, like 16yearold devin, shes a hero. Life . Adoption . She was born in october of this year. I wanted to have an abortion when i found out i was pregnant with my daughter. And i was given the options that i could do abortion and not tell anyone, or i could leave home. In october i placed my daughter for adoption. And because of her, im not ashamed i got pregnant at my age anymore. Reporter hawkins regularly conducts what she calls sidewalk counselling outside planned parenthood clinics with student volunteers like sam from the university of new mexico. Whenever i sidewalk cancel, its usually in a back alley on top of a ladder so we can reach the women. Reporter but the young women on the other side, women who could be her class mates, are just as dedicated. Many feel that the greatest danger is to women, forced to turn to illegal, unsafe alternatives if the texas law is upheld. Since these laws have taken effect, theres been an increase in attempts at selfinduced abortion in texas. Because they simply cant make the trip that is now required in order to reach an abortion clinic. Reporter but for now, stephanie has done what she can. The eight remaining justices. Abortion is a human right reporter but no matter the ruling, well likely see this scene play out again and again. Pro women, prolife reporter this battle isnt ending anytime soon. For nightline, im Gloria Riviera in washington, d. C. Next modern family star ariel winter opening up about why she chose to have a breast reduction. And later, astronaut scott kelly returns home.

Modern family star ariel winter grew up in the limelight, facing Harsh Criticism constantly. Now she is speaking candidly about her breast reduction surgery and opening up about what she says was a troubling childhood. Im not. But thats okay im the smart one. Reporter we fell in love with her as alex dunnphy, the brainiac middle child on modern family. Ha beating me in words with friends. How is that possible . Reporter we watched her grow up on screen from an 11yearold girl to an 18yearold woman. And just last year, when she was 17 years old, she decided to undergo breast reduction surgery going from a 32f to a 32d. Why did you decide ultimately to i had wanted to get a breast reduction since i developed, because i was in excruciating pain, and i couldnt sit up straight. It was always super uncomfortable for me to sleep. Its uncomfortable to sit. Uncomfortable to walk. I remember breaking down in dressing rooms because i couldnt find a bathing suit because they had no top that would fit me. I just didnt feel right. And i did it for myself. It was the best change i ever made in my life. Whats been the most noticeable change post surgery for you . I think maybe my mood. In general. I think im just much happier. And i just feel a lot more secure with myself. Reporter youre lighter in every way. Exactly. Reporter you wores a stunning gown to the sag awards, and you were not afraid to show your scars. No, i wasnt. I didnt even notice them. I didnt think to cover them. I didnt even think twice. It really astoubded me when i was getting comments from people were gross. And i think its so ridiculous considering they are a part of me. Theyre not going away. Scars, and theres nothing wrong with scars. Reporter scars are cool. Ive got them too. They are cool. Weve got stories from them. Reporter although shes young, winter says shes already had a lifetime of challenging experiences. You were thrust into the limelight at a very young age. Were you prepared for what came with that . I dont think anyones prepared to be so young and having everybodys eyes out, especially now as ive gone through some of my really some really big moments in my life being in front of the spotlight. It has been pretty difficult, because you have everybodys opinions. So i think it was a little shocking for me in the beginning. Reporter part of that shock was from the public scrutiny. Online bullying and body shaming she experienced. Walking down the red carpet and having every headline be about my cleavage, and not about my talent and what i was really there for or anything that i wanted to be put out there. And i thought that was really disappointing. Reporter just the fact that were sitting here discussing your decision, and what went have breast reduction surgery, i mean, is it crazy to you that the level of scrutiny girls and women face each and every day, camera . I think its absolutely ridiculous. It really bothers me. But, you know, i can only do my part. Reporter shes hoping her experience will help other girls, and wishes for a day when women in hollywood are no longer scrutinized for their looks. But despite her success as an actress, she says its a path she might never have chosen. I think that when i was born, it was kind of already decided what i was expected to be. And so i was kind of pushed into the industry. Thats not to say i dont love it and its not my passion now. I do love it. Reporter her work as an actress started when she was just 4 years old. From there, the tv roles came one after another, guest starring in crossing jordan. She says he didnt love us. Come on, sweetie. Wake up. Reporter and criminal minds. I want to find my mommy. Reporter she even appeared on the final six episodes of e. R. As a girl whose mother needed a heart transplant. And shes been working ever since. Reporter did you have what most people would say is a stage mom . She most definitely was. This is what she wanted me to do. And she pushed very hard for that. And kind of put that in the forefront of her mind instead of what i wanted and what i needed. And that was definitely hard. But i dont think that was the only issue. Reporter winter went through several years of legal battles with her mom over allegations of emotional and physical abuse. In a statement to abc news, winters mother said to further her career, ariel is conjuring up stories, and i deny all of ariels accusations. Ultimately, the actress became emancipated from her mother. It wasnt a supportive, loving home. I had a really tough time. Reporter winter is not the only kid star who emancipated home alone actor Macaulay Culkin did it after a financial dispute and custody battle. And then there was actress drew barrymore, who emancipated at 14. According to her memoir, she and her and her mother havent had much contact since. Do you have a relationship with your mom at this point . We havent spoken in three years. Its really hard to have that kind of drama in your life and have an open court case and have everybody look at it. Its hard for abuse victims, but its harder in the public eye when everybody has an opinion and there is no black and white of the situation. Reporter you refer to yourself as an abuse victim. What happened to you . Well, the thing is its really hard to talk about. And the reason i havent talked about it thus far is because it was really painful for me to watch my mom go on news outlets and go on dr. Phil and kind of spread things everywhere when its really just private family i feel like for me, i probably should take the high road and do something that i would have wished she would have done for me. Reporter and for now, shes closing that chapter and doing normal 18yearold things. Its always been a dream of mine to go to college. Reporter shes applying to colleges with plans to become a social justice lawyer. Ive had a lot of Life Experience that i think has really helped me grow into the person i am today. And i think its something that shaped what i wanted to be in my future. Reporter for nightline, im amy orrback in los angeles, california. Scott kelly returns home. Could the answer to growing taller and younger be here, spinning in space . Abc news nightline brought finally tonight, astronaut scott kelly is back on earth, proving it may just take a Rocket Scientist to find the fountain of youth. Heres abcs david wright. Reporter 340 days after he slipped the surly bonds of earth, scott kelly is finally home. Overnight, his soyuz capsule splashed down in kazakhstan, kelly testing the earths gravity with a fist pump. I f lt like i had been up there my whole life. Reporter in an odd way, he has. In one year of zero gravity, he circled the earth more than 500 times. Thats 15 years of sunrises. You could say that now makes him 15 years older than his astronaut mark kelly. But Albert Einstein would argue the opposite. Einsteins twin paradox maintained that a twin hurtling through space on a rocket ship would age more slowly than the twin remaining on earth. Another difference, scott is now apparently two inches taller, his spine likely stretched while he was in orbit. Nasa will now be studying that, comparing the two. All of which may sound like a scifi movie, and its tempting to think of scott kelly a bit like another fictional astronaut. Back home. You blew it up reporter a year ago the super tuesday results would have been as unthinkable as well, the planet of the apes. Damn you all to hell reporter in a year, the blink of an eye, the unthinkable has come to pass. Thank you very much. I appreciate it. The rocket man . Im david wright for nightline in new york.
