NEW YORK (CBSNewYork/AP) — A child welfare agency has begun an investigation into former New York congressman Anthony Weiner following yet another sexting scandal.

Weiner confirmed to The New York Times on Thursday that he had received a letter from the New York City Administration for Children’s Services about the investigation.

On Sunday, the New York Post published photos it said Weiner had sent last year to a woman he had never met. It said one of the photos showed Weiner in his underpants while lying on a bed with his 4-year-old son.

Weiner is now separated from his wife, Huma Abedin, a top aide to Democratic presidential candidate Hillary Clinton.

Abedin issued the following statement Monday:

“After long and painful consideration and work on my marriage, I have made the decision to separate from my husband. Anthony and I remain devoted to doing what is best for our son, who is the light of our life. During this difficult time, I ask for respect for our privacy.”

A sexting scandal cost Weiner his seat in Congress in 2011 and damaged his bid for the Democratic mayoral nomination two years later. But in the past, Abedin said she loved her husband and would stand by him.

“I made the decision that it was worth staying in this marriage,” Abedin said in a 2013 news conference at Weiner’s side following a round of sexting allegations.

When asked two weeks ago in a New York Times question-and-answer article whether he was still engaging in the activities that got him in trouble, Weiner would not answer.
