Once a congressman and a New York mayoral candidate, Anthony Weiner completed a precipitous fall from grace Monday, surrendering at a federal prison medical center in Devens, where he is expected to try to join a treatment program for sex offenders.

“Anthony Weiner is currently located at the Federal Medical Center (FMC) Devens,’’ a Bureau of Prisons spokeswoman wrote in an e-mail.

Weiner, 53, will serve one year and nine months for sending sexually explicit pictures and messages to a 15-year-old girl in North Carolina. In court papers, his attorneys have acknowleged he was “sexting” a large number of women at the same time he contacted the teenager.


Weiner pleaded guilty in May to one count of transferring obscene material to a minor. His sexting scandal cost Weiner his seat in Congress and his bid to become mayor of New York City, and it even ensnared Democrat Hillary Clinton during the waning days of last year’s presidential campaign.

During the probe into Weiner’s communications with the teenager, investigators unearthed e-mails on his laptop belonging to his wife, Huma Abedin, a senior aide to Clinton.

That discovery led to an announcement in late October by James Comey, then the FBI director, that the bureau had opened a new inquiry into Clinton’s handling of official e-mail. The inquiry ended two days before the election. Clinton has blamed Comey, in part, for her defeat.

In a sentencing memorandum filed by Weiner’s defense team, the Devens facility was listed as one of two federal prisons that offers residential treatment for sex offenders. The other is in Marion, Ill.

Joseph D. Allen, an attorney with the National Center on Institutions and Alternatives in Baltimore, provided Weiner’s lawyers with information about both facilities in a letter dated Sept. 8 but cautioned that the New York politician isn’t likely to get sex-offender treatment in prison.
