Top U.S. newswoman Elizabeth Vargas has completed rehab treatment for alcohol abuse.

The co-anchor of news show 2020, who is married to singersongwriter Marc Cohn, announced earlier this month (Nov13) that she had checked into a medical facility at the end of October (13) to tackle her issues.

She has since completed her addiction programme and she reached out to her Twitter.com fans on Tuesday (19Nov13) to thank them for their continued support.

She writes, "Hello everyone! I am home, and so grateful for all your support and well wishes. I am so much better and taking it one day at a time".

The 51 year old is expected to return to the Friday night news programme in the near future.
