Matt Gaetz associate Joel Greenberg reportedly used a confidential state datable to find out private information about celebrities and political adversaries. Greenberg — who plead guilty to multiple federal offenses, including sex trafficking of a 17-year-old girl — had access to the Driver and Vehicle Information Database (DAVID) and used it to search information on approximately 700 people between 2017 and 2020, the Orlando Sentinel found in a report released Tuesday. Among the searches made by Greenberg were Britney Spears, Justin Timberlake, and Greenberg's rival Democratic candidate for tax collector and radio personality, Lynn Dictor. Reps for Spears and Timberlake could not be reached for comment. Justin Timberlake and Britney Spears.

Dictor, who was among those in Greenberg's search using the DAVID system, told the outlet, "I don't know what he did with that information. Nothing you could say would surprise me about the depths to which Joel Greenberg would sink to." "This was an activity by the former tax collector that was not condoned by the DAVID system, and we are working to make sure that this sort of activity does not happen again," Alan Byrd, a spokesperson for the Seminole County tax collector's office, told Newsweek. A rep for Greenberg, 39, did not immediately respond to PEOPLE's request to comment. A Sex Trafficking Investigation, a Missing Spy & More: What to Know About the Case Against Matt Gaetz The latest probe into the politician's past comes months after he pleaded guilty to six criminal charges, including sex trafficking of a 17-year-old girl, a press release from the Department of Justice (DOJ) stated in May. "Greenberg faces maximum terms of imprisonment of 20 years for wire fraud, 15 years for illegally producing a false identification document, 15 years for conspiracy, and 5 years for stalking. He also faces mandatory minimum sentences of imprisonment: of 10 years, and up to, life in prison for sex trafficking of a child, and of 2 years for aggravated identity theft," the DOJ said. "Greenberg will be ordered to pay restitution to his victims in amounts to be determined at his sentencing." The New York Times reported at the time that Greenberg told prosecutors he'll work with the Justice Department's investigation — something that could potentially implicate Gaetz, 39. Gaetz has not been charged with any crime but has been embroiled in the case since late March. News broke that month that Gaetz is under federal investigation for possible sex trafficking. The Times reported the investigation is centered on the 17-year-old girl Greenberg admitted meeting on a sugar daddy website and paying via Venmo for sex on several occasions, according to court papers cited by multiple media outlets. A Vanished FBI Agent and His Family Are Now Caught Up in Matt Gaetz's Case Gaetz — a Florida congressman and Republican ally to Donald Trump — has disputed reports that he's being investigated in the same case, instead suggesting he's the subject of an "extortion" plot. "No part of the allegations against me are true," Gaetz said in a statement at the time. He added: "I have a suspicion that someone is trying to recategorize my generosity to ex-girlfriends as something more untoward." Suspicion of Gaetz's involvement in the case concerning Greenberg was heightened after The Daily Beast reported in April that it had reviewed Venmo records between the associates from 2018, in which Gaetz sent Greenberg an identical sum to what Greenberg then sent, in three payments, to three women.
