Theres talk of broken heart syndrome this morning with moms death coming so soon after her daughters. Is that a valid medical phenomenon. It is a real medical condition. I think it is possible figuratively and literally to die of a broken heart. Doesnt seem to be the case for Debbie Reynolds but theres reports of spouses dying hours or days amart from each other. The loss of a child is known to be one of lifes greatest stressors, whether that child is 6 or 60. So when youre talking about an elderly person with known preexisting medical conditions certainly the loss of a child can be a massive emotional and physical event. Lets bring you in, jess. Mother and daughter, they were estranged for about a decade but had so many personal tragedies between the two of them. Do you think that gave them an unbreakable bond and ultimately brought them back together. Ultimately it did. I think that Carrie Fisher went through, you know, as she spoke about so publicly a lot of addiction issues and so i think probably through a lot of therapy she learned to be grateful for this woman who had shaped her life and made this life possible for her and given her this extraordinary life and she learned to let go of the resentments because, you know, Debbie Reynolds was she was great on stage and she was great on screen. At home things were much more difficult for her. Life was hard sometimes. Yeah, life was certainly hard but had that breakout role at 19 in singin in the rain next to gene kelly but her career spanned over 60 years. Why do you think she had such longevity . She was incredibly talented and well liked and great comic actress. Underrated. One of the best so while one generation knows her from singin in the rain, another knows her from will grace as graces mom and she was fantastic. If youve ever seen mother with Albert Brooks she should are won an oscar for that film. She was always great. And, frankly, she loved to work and had to work. Jess cagle, dr. Ashton, thank you both. We appreciate it. Well speak more with dr. Ashton in our next hour about Carrie Fisher and her mom and the deaths coming so close together. Also overnight a tweet.

Back over to you. Today the white house is expected to announce how it will respond to allegations of russian hacking during the president ial campaign. What will these new punitive measures be and will the russians retaliate . Abcs david kerley is on the story from washington. David, good morning to you. Reporter good morning. Sources are telling us the Obama Administration will be public today in announcing retaliation and providing more details on why it is so sure russia hacked and interfered with the u. S. Election. This morning, sources tell abc news russia will soon face punishment for meddling in the u. S. Election. The Obama Administration getting ready to announce economic sanctions as early as today. It is now time for russia to understand enough is enough. Reporter this public retaliation coming after weeks of debate inside the white house on a response to those cyberattacks leading up to the election. Attacks u. S. Intelligence agencies say were meant to embarrass Democratic Party leaders including Hillary Clinton and help donald trump. The president elect weighing in on the coming sanctions taking the opposite position. I think we ought to get on with our lives. I think the computers have complicated lives very greatly. The whole, you know, age of computer has made it where nobody knows exactly whats going on. We have speed. We have a lot of other things but not the spirit you need. Reporter Martha Raddatz asked president obama about the evidence of russian involvement. Just to be clear, do you believe Vladimir Putin himself authorized the hack. What i can tell you is that the intelligence that ive seen gives me great confidence in their assessment that the russians carried out this hack. Reporter Russias Foreign Ministry posting a response on its website saying, quote, if washington actually takes new hostile steps, then it will get a response. Now, this is not the end of the obama investigation of the hacks themselves. And it is unlikely that this will be the only retaliatory steps that the u. S. Takes against russia including the possibility, dan, of covert cyberactions. Well, in terms of covert operations, who or what would we be going after and how . Reporter there is a wide range. If they know exactly who did these hacks they could go after them directly or go after members of the government, could go after members of some of the oligarchs. There is a vast possibility. The question is do you want to start a cyberwar, something the Obama Administration has been very worried about as its been talking about what action to take against russia. A lot of fear this could open up a pandorpandoras box. More fiery rhetoric from donald trump slamming u. S.

Overnight donald trump emerged from his maralago estate with praise for president obama and the president ial handoff. Our staffs are getting along very well and im getting along we develop with him other than a couple of statements. That i responded to and we talked about it. Reporter with boxing promoter don king by his side the president elect said he just had a very good talk with the president. I actually thought we covered a lot of territory. Reporter but just hours earlier a very different tone. Trump slamming obama for getting in the way of the transition. Trump tweeting doing my best to disregard the many inflammatory president obama statements and roadblocks. Thought it was going to be a smooth transition, not. This is the current and future president faceoff over one of americas top allies, israel. Trump tweeting we cannot continue to let israel be treated with such total disdain and disrespect. The president elect has been criticizing the Obama Administration for allowing the u. N. To condemn israel for building settlements, a move that broke with longstanding tradition. Secretary of state john kerry is passionately defending the decision saying those settlements put the possibility of peace in jeopardy. And we cannot properly defend and protect israel if we allow a viable twostate solution to be destroyed before our own eyes. Reporter infuriated israeli Prime Minister netanyahu is firing back. I must express my youkerrys remarks speak for themselves. The president elect says he thinks israel is being treated unfairly and that the u. N. Has tremendous potential, but isnt living up to it. Dan. Yes, and trump is promising big change come january 20th. Mary, thank you.
