The teen, whom Weiner's lawyers only refer to as Jane Doe, or JD, first contacted him on January 23, 2016, while Weiner was "laid up in his apartment by a record-setting blizzard in Manhattan", his lawyers said.
In a lengthy sentencing submission in the US District Court for the Southern District of New York, Weiner's lawyers argued the former congressman was suffering from a "sickness" when the then-15-year-old girl reached out to him via Twitter "looking to generate material for a book the Government has disclosed she is now shopping to publishers".
Weiner pleaded guilty in May to a charge of transferring obscene material to a minor, ending a freaky saga that negatively impacted his wife's boss. The girl at the center of the controversy was seeking "somehow to influence the USA presidential election, in addition to securing personal profit", his lawyers argue, and the girl is now seeking a book deal related to her experience.
In late October, eleven days before the 2016 Presidential election, then-FBI director James Comey sent a letter to Congress claiming that emails pertinent to the closed investigation of Clinton's use of a personal email server were found "in connection with an unrelated case", believed to be the investigation into Weiner's communication with the minor.
The two also appeared at divorce hearing on Wednesday. Weiner must also register as a sex offender and surrender his iPhone. The charge carries a maximum sentence of 10 years.
"Anthony and I have a wonderful son", Huma Abedin, a 41-year-old top aide to Hillary Clinton, wrote in the letter, which is largely redacted. Even as the lawyers recounted the girl's role in encouraging Weiner to participate in the explicit message exchange, they said in the court filing that Weiner "never should have responded" and he doesn't treat the circumstances "as a justification".
It was shortly after that article was published that reports surfaced of a federal investigation into Mr. Weiner's conduct.
Weiner, 53, submitted his own letter to the court in which he apologized and said he was continuing to seek treatment.
"This is not a letter I ever imagined I would write, but, with Anthony, I have repeatedly found myself in circumstances I never imagined".
Huma Abedin, who is seeking a divorce, wrote to the judge as well, saying that she is "devastated by Anthony's actions" and understands "he must face their consequences".
As part of the FBI investigation, agents seized Weiner's laptop computer, which had emails to Abedin, a senior adviser to Clinton's presidential campaign. Weiner ran for mayor of New York City in 2013, a bid scuttled by a similar sexting scandal. Clinton has said that the announcement played a factor in her losing the election.
He said "the one ideal thing in my life - my son - will forever have to answer questions about the public and private failings of his father".
Weiner mounted a comeback bid for NY mayor in 2013, but his prospects softened when a woman named Sydney Leathers revealed he sent her raunchy messages under the pseudonym "Carlos Danger".
