Most recently, in 2010, president obama signed a deal to cut the number of missile launchers in half and limit deployed warheads on both sides. But today, donald trump suggested that policy may not be his policy. Heres Julianna Goldman. Reporter in just 140 characters, president elect donald trump signaled a major shift in u. S. Foreign policy, tweeting transition officials didnt say what prompted the tweet, but it came the same day that russian president , vladimir putin, said moscow needs to strengthen the military potential of Strategic Nuclear forces. I think the tweet was ambiguous, and it was hard to figure out what exactly he meant. Reporter former u. S. Ambassador to nato, nicholas burns. In Nuclear Diplomacy and in diplomacy in general, you want to be clear, most of the time especially with your adversaries about what youre willing to do and not willing to do. Reporter a trump aide later tried to clarify saying the president elect was, referring to the threat of Nuclear Proliferation and the critical need to prevent it. During the campaign, mr. Trump also sent conflicting messages on nuclear policy. Look, nuclear should be off the table. But would there be a time when it could be used . Possibly. Okay, the trouble swhen you said that reporter todays confusion overshadowed mr. Trumps longawaited white house staff anowms, including naming former Campaign ManagerKellyanne Conway as counselor to the president , making her the topranking woman in the west wing.

Reporter the memo did not ask for the names of officials who oon these programs, unlike a controversial questionnaire sent by the trump team to the Energy Department earlier this month. It requested a list of programs and staffers essential to meeting the goals of president obamas Climate Action plan. The questionnaire prompted House Foreign AffairsCommittee Democrats to urge secretary kerry in a letter last week not to single out hills employees. Today, kirby said there is a limit to the help the state department will provide. Obviously, we would have concerns if if, for instance, therthere were issuespecific ls of names that were being provided.

While powerful medicine clears your worst cold symptoms. Start the relief. Ditch the misery. Lets end this. The possibility of a flare was almost always on my mind. Thinking about what to avoid, where to go. And how to deal with my uc. To me, that was normal. Until i talked to my doctor. She told me that humira helps people like me get uc under control and keep it under control when certain medications havent worked well enough. Humira can lower your ability to fight infections, including tuberculosis. Serious, sometimes fatal infections and cancers, including lymphoma, have happened; as have blood, liver, and nervous system problems, serious allergic reactions, and new or worsening heart failure. Before treatment, get tested for tb. Tell your doctor if youve been to areas where certain fungal infections are common, and if youve had tb, hepatitis b, are prone to infections, or have flulike symptoms or sores. Dont start humira if you have an infection. Raise your expectations. Ask your gastroenterologist about humira. With humira, control is possible. But i keep it growing by making every dollar count. Thats why i have the spark cash card from capital one. With it, i earn unlimited 2 cash back on all of my purchasing. And that unlimited 2 cash back from spark means thousands of dollars each year going back into my business. Which adds fuel to my bottom line. Whats in your wallet .

Reporter pediatric audiologist brian fligor has studied the impact of headphones on hearing. We are seeing pockets of young people who have worse hearing than you would expect, much worse hearing than youd expect. Reporter when it comes to loud sound, the general rueful thumb is the greater the volume, the shorter want acceptable duration. Turn up the music reporter the top volume on an apple music player is 102 decibels, as loud as a leaf blower. Turn up the music reporter keeping the volume at 70 , or 82 decibels is safe for eight hours a day. 80 volume or 89 decibels is safe for 90 minutes. But crank it all the way up, and only 10 minutes is safe. How many people listen to personal music players . Reporter these fifth graders in cleveland heights, ohio, are learning what it takes to be a good listener. Do you think youre listening at a safe level .

Including this little girl. And what if this happened again . I was given warfarin in the hospital, but wondered, was this the best treatment for me . So i asked my doctor. And he recommended eliquis. Eliquis treats dvt and pe blood clots and reduces the risk of them happening again. Yes, eliquis treats dvt and pe blood clots. Eliquis also had significantly less major bleeding than the standard treatment. Both made me turn around my thinking. Dont stop eliquis unless your doctor tells you to. Eliquis can cause serious and in rare cases fatal bleeding. Dont take eliquis if you have an artificial heart valve or abnormal bleeding. If you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. While taking eliquis, you may bruise more easily. And it may take longer than usual for bleeding to stop. Seek immediate medical care for sudden signs of bleeding, like unusual bruising. Eliquis may increase your bleeding risk if you take certain medicines. Tell your doctor about all planned medical or dental procedures. Eliquis treats dvt and pe blood clots. Plus had less major bleeding. Both made eliquis the right treatment for me. Ask your doctor if switching to eliquis is right for you. When i was too busy with the kids to get a repair estimate.
