“Oof.” That was Hillary Clinton Communications director Jennifer Palmieri’s reaction to the news that police had visited a home in New Castle, Delaware to question a 17-year-old girl about online communications with Anthony Weiner.

Weiner’s problems with underage girls was known by campaign staff, even before the Clinton’s 2016 campaign officially launched.

Partisan journalist Lee Fang sent an email to Joshua Dorner, who forwarded it to Palmieri and communications aides as well as John Podesta and Clinton loyalist Neera Tanden. The email was released by WikiLeaks on Monday, as part of their ongoing release of emails from Podesta’s private email account.

The high school junior had visited Weiner as part of a class trip to Washington D.C. and followed him on Twitter afterward. Weiner direct messaged her on Twitter on April 13, according to the report.

In 2011, Weiner confirmed that he contacted the girl, but denied that he engaged in inappropriate behavior.

The report took place after he admited he sent lewd pictures of himself online, but before he resigned from Congress.
