20/20 Anchor Back in Rehab

(Newser) – ABC anchor Elizabeth Vargas checked herself back into rehab for alcohol dependency while on vacation. In a statement, the 20/20 co-anchor wrote that overcoming the disease is an "incredibly difficult process. I feel I have let myself, my co-workers, and most importantly my family down and for that I am ashamed and sorry." ABC confirmed the news and seemed supportive: "We look forward to having her back at ABC News when she feels ready to return." Vargas, 51, entered treatment last fall for alcohol dependency as well.
