Story highlights Weiner pleaded guilty Friday to transferring obscene material to a minor

Abedin, a top aide to former Democratic presidential nominee Hillary Clinton, was not present at the hearing

(CNN) Huma Abedin has filed for divorce from former Rep. Anthony Weiner, a move she made prior to Weiner pleading guilty Friday to transferring obscene material to a minor, a source familiar with the matter told CNN.

Abedin, a top aide to former Democratic presidential nominee Hillary Clinton, was not present at Friday's hearing.

A message left with a representative for Abedin seeking comment Friday morning was not returned.

At the hearing Friday, Weiner accepted responsibility for his conduct. "I have a sickness, but I do not have an excuse," he said through pauses and bouts of tears in an emotional statement. "I entered intensive treatment, found the courage to take a moral inventory of my defects, and began a program of recovery and mental health treatment that I continue to follow every day."

As part of the plea agreement, Weiner, 52, will register as a sex offender and also will have to forfeit his iPhone, surrender his passport and continue mental health treatment. He is also barred from having any contact with the minor.
