The ABC News reporter and “20/20” co-anchor released a statement explaining, "As so many other recovering alcoholics know, overcoming the disease can be a long and 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."
Vargas, who is married to singer Marc Cohn and is a mother of two, said she is "committed to battling and addressing this debilitating disease."
ABC News released a statement saying the network is “squarely behind her… We look forward to having her back at ABC News when she feels ready to return."
She said in the interview, "I dealt with that anxiety, and with the stress that the anxiety brought, by starting to drink."
