Investigators believe Joel Greenberg, the former tax collector in Seminole County, Fla., who was indicted last year on a federal sex trafficking charge and other crimes, initially met the women through websites that connect people who go on dates in exchange for gifts, fine dining, travel and allowances, according to three people with knowledge of the encounters. Mr. Greenberg introduced the women to Mr. Gaetz, who also had sex with them, the people said.
One of the women who had sex with both men also agreed to have sex with an unidentified associate of theirs in Florida Republican politics, according to a person familiar with the arrangement. Mr. Greenberg had initially contacted her online and introduced her to Mr. Gaetz, the person said.
Mr. Gaetz denied ever paying a woman for sex.
The Justice Department inquiry is also examining whether Mr. Gaetz had sex with a 17-year-old girl and whether she received anything of material value, according to four people familiar with the investigation. The sex trafficking count against Mr. Greenberg involved the same girl, according to two people briefed on the investigation.
