doug brinkley, it will be a date, i promise you. thank you so much. appreciate that. >>> coming up next -- >> thank you, brooke. >> you got it. >> some undecided voters admit they have an odd decision to make, donald trump or bernie sanders. that's where a lot of people in new hampshire are torn. hear why they come down to deciding these two men. hi, i'm leeza gibons with an amazing story about how philips lifeline gives betty white peace of mind and gave my father a second chance at life. daddy is invincible. that's how we want to think about our parents. knowing that dad lives alone, we worry. that's why was so hard for all of us when he had his heart attack. i wasn't feeling well that day. the heart attack hit me, i fell to the floor, and i was trying to crawl back to the bed. of course in excruciating pain. i'm alive today because of philips lifeline. philips lifeline is the number one medical alert service in the u.s. today. you get fast easy access to help any time. daddy was been a little resistant. because he didn't want to seems vulnerable. h
