“20/20” anchor Elizabeth Vargas has checked out of rehab — she tweeted the news herself Tuesday afternoon. “Hello everyone! I am home, and so grateful for all your support and well wishes,” she wrote. “I am so much better and taking it one day at a time. :)” ABC confirmed earlier this month that Vargas, 51, was spending time in a treatment facility. “Like so many people, I am dealing with addiction,” she said at the time. “I realized I was becoming increasingly dependent on alcohol.”
