Apparently, Elizabeth has an alcohol addiction problem, which explains why she's not been on TV recently. Hope she gets better.
“Like so many people, I am dealing with addiction. I realized I was becoming increasingly dependent on alcohol. And feel fortunate to have recognized it for the problem it was becoming. I am in treatment and am so thankful for the love and support of my family, friends and colleagues at ABC News. Like so many others, I will deal with this challenge one day at a time. If coming forward today gives one other person the courage to seek help, I’m grateful.”
