A new report found that David Nieland may have resigned in August after being implicated in an incident also involving prostitution

An investigator who led an internal review of the 2012 Secret Service prostitution scandal resigned in August because he had been implicated in an incident involving prostitution, according to a new report.

Officials said the investigator, David Nieland, was seen entering and leaving a building that was being monitored as part of a prostitution investigation, which was unrelated to the Secret Service scandal, the New York Times reported. When they interviewed the prostitute, she identified Nieland and said he had paid her for sex.

Nieland had cited health problems for his resignation, but officials said he stepped down after refusing to answer questions asked by a Department of Homeland Security official regarding his activities. Nieland denied the reports, stating to the New York Times in an e-mail that, “The allegation is not true.”

A Department of Homeland Security spokesman said an investigation is underway.
