ABC News reporter Elizabeth Vargas has returned to a recovery center to be treated for alcohol dependency.
The "20/20" anchor said in an emailed statement Sunday that she checked into a facility this weekend while on vacation.
She says she's committed to battling the disease and apologized for letting down her family and co-workers.
The network said in a statement that it supports Vargas and looks forward to having her return to ABC News.
Vargas announced in November 2013 that she was in rehab. She acknowledged in an interview that aired in January on "Good Morning America" that she was an alcoholic and it took years for her to admit it.
She said she had suffered panic attacks since she was a child and dealt with the stress by drinking.
