NYC Children's Services investigating Anthony Weiner's interactions with son

NEW YORK (WABC) -- A city official says the Administration for Children's Services has opened an investigation of Anthony Weiner's interactions with his four-year-old son.

The probe is described as routine. It is unclear if investigators have talked to Weiner.

Earlier this week, Hillary Clinton aide Huma Abedin said that she is separating from the former New York congressman after he was accused in yet another sexting scandal.

The New York Post published photos late Sunday that it said Weiner had sent last year to a woman, whom it identified only as a "40-something divorcee" who lives "out West" and is a supporter of Donald Trump.

The photos included several shots of Weiner bare-chested and two close-ups of his bulging underpants. one of the pictures, Weiner is in bed with his son Jordan while he is texting the woman, according to the Post. The tabloid also ran sexually suggestive text messages that it said the two exchanged.

Weiner told the Post that he and the woman "have been friends for some time."

"She has asked me not to comment except to say that our conversations were private, often included pictures of her nieces and nephews and my son and were always appropriate," he told the newspaper.

Weiner, a Democrat, quit Congress in 2011 after it discovered that he was sending women sexually explicit messages. Weiner ran for mayor of New York in 2013, but that bid collapsed after it was reported that he was continuing to sext women.

A spokeswoman for the Administration for Children's Services cited the agency's longstanding policy of declining to comment on specific cases to protect the privacy of the child involved.

The agency released a statement:

"In order to protect children and their privacy, ACS does not comment on specific cases or allegations of child maltreatment, regardless of whether or not allegations have been reported, are being investigated, or have not resulted in an investigation."
