Congressional House Ethics investigators have obtained text messages allegedly showing that a few months after first joining Congress, Florida Rep. Matt Gaetz asked a young woman,
who at the time had received payments for sex from Gaetz's then-close friend Joel Greenberg, to join him and others on a three-day trip to the Florida Keys in May 2017, multiple sources tell ABC News.
In the alleged text messages described exclusively to ABC News, the then-freshman congressman appeared to message a woman, who ABC News is not identifying, asking if she would fly on a private plane to the Florida Keys for a trip with Gaetz, three other women, and one other man......
....Sources familiar with the events tell ABC News the woman ultimately declined the 2017 trip.
The messages, if accurate, mark the first known example of alleged direct private communication between the Florida congressman and a woman who his one-time close associate Joel Greenberg told investigators he had been paying to have sex with other men, according to documents and interviews with multiple sources.
It's unknown if Gaetz knew that Greenberg had allegedly been paying the woman in such a manner.
