Disgraced former congressman Anthony Weiner is under federal and local investigation for allegedly engaging in a sexual relationship with an underage girl, CNN, ABC and CBS reported.

A law enforcement source confirmed the reports to The Huffington Post Thursday.

According to CNN, the office of U.S. Attorney Preet Bharara has subpoenaed the New York Democrat’s phone records. The FBI and New York Police Department are also reportedly investigating the charges.

A spokesman for the NYPD confirmed that Weiner was being investigated, but did not comment on the charges. The U.S. Attorney’s office declined to comment.

The news of the investigations came one day after the Daily Mail published a story accusing Weiner of exchanging explicitly sexual texts messages with a 15-year-old girl. Weiner has acknowledged texting with the girl but claimed on Wednesday that he was “the subject of a hoax.”

Weiner resigned from Congress in 2011 after he was caught sending sexually explicit photos to women on social media. He then attempted to revive his political career by running for mayor of New York City in 2013. In the midst of his campaign, it was revealed the former congressman took part in another sexting scandal the previous year. Weiner lost the Democratic primary to Bill de Blasio, who was ultimately elected that November.

In August, the New York Post reported that Weiner had again sent explicit messages to a woman, including an image where he posed next to his 4-year-old son.

It appeared to the be the last straw for Weiner’s wife of six years, Huma Abedin, a longtime Hillary Clinton aide. Abedin announced her separation from Weiner just hours after the Post’s story published.
