Weiner pleaded guilty to a charge of transmitting sexual material to a minor and could get years in prison. He said he continues to follow the treatment daily.
Anthony Weiner, the disgraced former congressman from NY, pleaded guilty Friday to one charge of transferring obscene material to a minor after he was investigated for sending sexual messages to a 15-year-old girl last year. Mr. Weiner will plead guilty to a single charge of transferring obscene material to a minor, pursuant to a plea agreement with the United States attorney's office in Manhattan, one of the people said. Through approximately March 2016, I engaged in obscene communication with this teenager, including sharing explicit images and encouraging her to engage in sexually explicit conduct, just as I had done and continued to do with adult women.
"These destructive impulses brought great devastation to family and friends, and destroyed my life's dream of public service", Weiner said.
The FBI began investigating the Democrat in September after a 15-year-old North Carolina girl told a tabloid news site that she and the disgraced former politician had exchanged lewd messages for several months. He said he knew his conduct was "as morally wrong as it was unlawful". "Through treatment I found the courage to take a moral inventory of my defects".
Weiner resigned from Congress in June 2011 after explicit pictures in an unrelated case became public, CNN reported.
The investigation into Weiner came to light after the Daily Mail, a British newspaper, published an interview with the North Carolina teen a year ago. I apologize to the teenage girl, whom I mistreated so badly.More news: Assange hails Swedish move to drop investigation
The Democrat will appear in court at 11 a.m., the US attorney's office in Manhattan said. "Yet I remained in denial even as the world around me fell apart". "Sentencing has been scheduled for September 8, 2017, at 11 a.m".
Investigators soon seized Weiner's electronic devices, including a laptop and a cell phone, as part of the probe into that picture, leading to a series of events that many say contributed to Clinton losing the election. She said that Weiner, then 51, carried out a monthslong sexually explicit conversation with her in which he asked her to undress and sent her semiclothed photos of himself.
Weiner is estranged from Huma Abedin, a top aide to former Democratic presidential nominee Hillary Clinton.
The inquiry was brief and Mr Comey announced shortly before the election that the new emails contained nothing to change his view that Mrs Clinton could not be charged with a crime, but she partly blamed her loss to Republican Donald Trump on Mr Comey's announcement.
Arlo Devlin-Brown, an attorney at Covington & Burling, said Weiner accepted "full responsibility" for his "inappropriate" actions, adding that Weiner would not further address the matter. The failed mayoral bid is the subject of the documentary Weiner.
