Federal investigators have established a web of payments among Matt Gaetz and dozens of friends and associates who are said to have taken part with him in drug-fueled sex parties, according to a document obtained by The New York Times. Among those who received money from Mr. Gaetz were two women who have testified that he hired them for sex, according to the document and a lawyer for the two women. The lawyer said payments to the women ultimately totaled around $10,000.
