Anthony Weiner's wife Huma Abedin: 'I have forgiven him'

New York mayoral candidate Anthony Weiner has admitted sending explicit messages to a woman, two years after he left Congress over a similar affair.

His wife, former Hillary Clinton adviser Huma Abedin, has said she knew of the messages that occurred after he resigned from Congress and that through "a lot of work and a lot of therapy", she had decided to stay in the marriage.

"I made the decision it was worth staying in the marriage," she said. "I love him, I have forgiven him, I believe in him."
