Gaetz's associate, former local politician Joel Greenberg, was indicted last year for allegedly trafficking a teenage girl for sex in 2017, and the Justice Department is also trying to determine whether Gaetz had sex with the 17-year-old, according to sources. Greenberg pleaded not guilty to the charges.
Gaetz's office did not respond to a request for comment, but earlier this week Gaetz insisted on Fox News that he never "had a relationship with a 17-year-old," calling such allegations "totally false."
According to the Times, investigators believe Greenberg met women through certain websites and introduced some of them to Gaetz. As recently as 2019 and 2020, Gaetz and Greenberg told women to meet them at hotels in Florida, laying out how much they were willing to pay beforehand, the newspaper said, adding that party drugs may have also been used by Gaetz and others at times.
"Matt Gaetz has never paid for sex," Gaetz's office said in a statement to The New York Times. "Matt Gaetz refutes all the disgusting allegations completely. Matt Gaetz has never ever been on any such websites whatsoever. Matt Gaetz cherishes the relationships in his past and looks forward to marrying the love of his life."
Sources told ABC News the investigation targeting Gaetz was launched last year, when Trump was still president. Then-Attorney General Bill Barr was briefed on the investigation's progress several times, the sources said.
A lawyer for Greenberg did not respond to ABC News' request for comment. Greenberg served a controversial stint as Seminole County tax collector until he resigned last summer following his arrest by federal authorities.
Prior to joining Congress, Gaetz was a member of the Florida House of Representatives when his father was also a member of the Florida Senate. Sources told ABC News the two were often referred to as "Daddy Gaetz and Baby Gaetz." Sources said some women referred to him as "Creepy Gaetz" because they allegedly found themselves made uncomfortable by the junior lawmaker.
Sources said Gaetz was part of a group of young male lawmakers who created a "game" to score their female sexual conquests, which granted "points" for various targets such as interns, staffers or other female colleagues in the state House. One of the targets of the scoring system was a group the lawmakers had heard were "virgins," according to a source. The scoring system by male Florida lawmakers was previously reported by the Miami Herald.
One source said Gaetz was often spotted trying to pick up young women at 101 Restaurant, a once-popular watering hole in Tallahassee for some lawmakers and students from nearby Florida State University.
While on Capitol Hill as a member of Congress, Gaetz allegedly boasted of his sexual encounters with women, and would allegedly try to show colleagues photos and videos of naked women he said he slept with, according to sources familiar with Gaetz’s actions.
One video in particular was of a naked woman with a hula hoop, according to a source who was shown the material -- an allegation first reported by CNN.
Gaetz's office did not respond to a request for comment.
During an interview on Fox News, Gaetz claimed he was being extorted over the investigation and claimed that someone had alleged there were "pictures of me with child prostitutes," which he said was "obviously false."
"There will be no such pictures because no such thing happened. But really on March 16 was when this got going from the extortion standpoint," Gaetz said.
Gaetz has previously sparked controversy over repeatedly commenting on Rep. Alexandria Ocasio-Cortez's appearance, calling the New York congresswoman "attractive" multiple times and once referring to her as the "attractive lady from Queens."
Gaetz developed a reputation in the U.S. House of Representatives for often bragging to colleagues about his relationships with women, sources told ABC News.
Upon his arrival to Washington, sources said Gaetz was often seen with young women at various social events, including at the Trump Hotel on Pennsylvania Avenue.
Gaetz previously told Axios, "The allegations of sexual misconduct against me are false." When asked what the DOJ probe could be about, he added, "I have definitely, in my single days, provided for women I've dated. You know, I've paid for flights, for hotel rooms. I've been, you know, generous as a partner. I think someone is trying to make that look criminal when it is not."
