U.S. Rep. Ann Kirkpatrick of Arizona is returning to Congress after a six-week absence for treatment of alcoholism.
The Democratic lawmaker told The Arizona Republic that she didn't know she had a problem with substance abuse until she fell on a Metro platform in Alexandria, Virginia, in January.
She says she's unsure how much wine she had with lunch before rushing to the Capitol for a vote that came three hours earlier than expected.
She suffered a fractured spine, cracked ribs and a gash in her head. She says she's grateful her injuries weren't more severe and appreciates the support of her family and congressional colleagues.
