Anthony Weiner had been messaging an underage girl as early as 2011, and Hillary Clinton's staffers reportedly knew about it, according to WikiLeaks emails.

Hillary Clinton's staffers knew as early as 2011 that Anthony Weiner had been messaging an underage girl, but they did nothing about it, according to WikiLeaks emails published Monday.

John Podesta - now chair of Clinton's presidential campaign - and Neera Tanden, another adviser, were forwarded news of an investigation into Weiner's online contact with a 17-year-old Delaware high school student by Jennifer Palmieri, the current campaign communications director, in June 2011.

At the time he was married to Huma Abedin, another member of Clinton's inner circle, who is now at the center of fresh FBI investigation into the handling of classified material while Clinton was in office.

The email detailed lurid claims of private messages to an underage girl being investigated by police - and was met with the response 'oof' by Podesta.

'Police on Friday afternoon came to the home of a 17-year-old high school junior to ask her about direct online communications she has had with Rep. Anthony Weiner,' email read, quoting a Fox News article from the same time.

'Two officers from the New Castle County Police Department arrived at the girl's home around 4:30 p.m. and asked to speak with the girl's mother about the daughter's contact with Weiner. Another officer appeared at the home a short time later.'

Palmieri forwarded the news article to Podesta and Tanden.

Six days later, on June 16, 2011, Weiner announced his resignation after accidentally tweeting a photo of himself in bulging briefs to all of his followers.

Despite that Abedin stood by him.

Sources close to the 17-year-old at the time told Fox News that the girl and Weiner had direct-messaged each other on Twitter.

Back in April 2011, the then-teenager openly expressed her love for Weiner, who followed her on Twitter.

In her feed, she expressed her love of married men, according to Patterico.com.

At one point she said: 'HE IS MINE ALL MINE HE LOVES ME AND NO ONE ELSE ILY ILY ILY!!!' and added '@RepWeiner I'm in love with you' two days later.

At the time Weiner admitted that he had contact with the girl, but denied sending inappropriate messages, according to Politico.

The FBI sensationally announced on Friday that it was investigating thousands of emails that might be related to the former secretary of state's private server.

The messages were taken as part of a separate FBI investigation into devices belonging to disgraced Weiner.

The former politician came under investigation after the DailyMail.com revealed he allegedly exchanged lewd text messages with a 15-year-old girl.

The disclosure came a month after Abedin had finally ended her marriage to him, which she had continued despite sexting scandal after sexting scandal.

The final straw was when in August of this year the New York Post revealed how Weiner sent a picture of himself sexually picture of himself in bed. His sleeping son was beside him.

It emerged Sunday that the FBI now has a warrant to search the emails, numbering some 650,000 according to the Wall Street Journal.

Coming after weeks of emails published by WikiLeaks - which have given voters an unprecedented insight into a candidate's political machine - Trump's campaign has seized on the revelations as further evidence that the Clinton dynasty cannot be trusted.

Clinton and her campaign have demanded that the FBI give specifics on what exactly they are investigating, while several key Democrats have accused the organization of breaking the law by trying to sway the election.
