Weiner pleaded guilty back in May to sexting with a 15-year-old girl in North Carolina.
His lawyers also pinned blame on the girl, who told investigators she wanted to influence last year’s Presidential election.
Weiner’s estranged wife Huma Abedin was a top aide to Hillary Clinton.
The two also appeared at divorce hearing on Wednesday.
In a letter to the judge, Weiner said he regrets his actions.
He was registered as a sex offender earlier this year.
He faces more than two years in prison when he’s sentenced later this month.
