Elizabeth Vargas

Veteran 20/20 co-anchor Elizabeth Vargas has checked into rehab, People reports.

"Like so many people, I am dealing with addiction," the journalist told the magazine. "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."
