Estranged husband of Hillary's aide pleads guilty to sexting!

• He pleaded guilty to one count of transferring obscenity to a minor.

Anthony Weiner, the disgraced former US congressman, estranged husband of one of Hillary Clinton's closest aides and former candidate for New York mayor pleaded guilty on Friday to sexting a school girl.

The 52-year-old, wearing a dark suit and tie, broke down repeatedly, sobbing as he read out a statement attesting to his guilt in a Manhattan federal court.

Weiner, once a rising talent in the Democratic Party, admitted to sending explicit photographs and messages to a 15-year-old high school girl last year as his wife worked on Clinton's presidential campaign.He surrendered to the FBI on Friday morning and was released on bail after agreeing to turn in his passport, limit his travel to New York and continue mental health treatment. He will also have to register as a sex offender.

"I am guilty your honor," he said. Speaking through tears, his voice cracking and his words at times inaudible, he apologised to all those he had hurt and for the "great devastation to family and friends."

"I knew it was morally wrong and unlawful," Weiner told the court, stopping to wipe his brow, sniff and sip water from a bottle.

"I have a sickness but I do not have an excuse," he said. "I apologise to everyone I have hurt."

He pleaded guilty to one count of transferring obscenity to a minor. The crime carries a maximum sentence of 10 years in prison. Federal prosecutors are seeking a jail term of 21-27 months for Weiner. District Judge Loretta Preska said Weiner would have to meet a probation officer for a pre-sentencing report. As part of the plea deal, he also has to surrender an iPhone.

Weiner, who put up a $150,000 bond, is scheduled to be sentenced on September 8. "Weiner's conduct was not only reprehensible, but a federal crime, one for which he is now convicted and will be sentenced," said acting Manhattan United States Attorney Joon Kim.

The former-lawmaker used online messaging and video chat applications to communicate knowingly with a teenager, sending her obscene material and directions to engage in sexual conduct, as well as sexually explicit images.

United States media reported shortly after the guilty plea that wife Huma Abedin had filed for divorce.

She announced their separation in August after The New York Post published sexually suggestive photographs that he shared with a woman while his four-year-old son apparently slept nearby.
