Rep. Matt Gaetz's future sister-in-law has blasted the Florida congressman's "weird and creepy" behavior on TikTok as the FBI and Justice Department continue to probe whether he broke sex-trafficking laws and had sexual relations with a minor.

Roxanne Luckey, 20, is the younger sister of Ginger Luckey, Gaetz's fiancée. Roxanne's TikTok account has since been taken private, but Insider viewed recordings on Twitter and YouTube.

In a statement to The Daily Beast, Ginger Luckey said her sister had a history of "destructive behavior." Gaetz, Roxanne Luckey, and Ginger Luckey did not immediately respond to Insider's request for comment.

What the videos say

In her first video, posted Sunday, Roxanne Luckey showed a New York Times article, which said the DOJ was investigating whether Gaetz had a sexual relationship with a 17-year-old girl. (The congressman has denied any wrongdoing.)

The caption of the video read: "When a creepy old man tries to hit on you at the bar but your sisters engaged to a literal pedophile."

In a Monday post, Luckey said Gaetz pressured his friend to date her last summer, when she was 19 and already in a relationship. She described the friend as being a divorced father "around Matt's age," 39.

"This guy kept telling me like: 'Oh, Matt told me I should ask you out, that we would be great together.' And I would just make jokes like: 'Haha, I'm 19, like, that's weird,'" Luckey said.

Luckey said the friend went on to say "creepy things," like: "When you break up with your boyfriend let me know, so you can have a real man.'"

Luckey said the friend later apologized, saying he asked her out "to get Matt off my back."

Luckey said when she confronted Gaetz at Thanksgiving, he "started yelling at me and my mom."

"He called me a narcissist, was just 1,000% gaslighting me ... He went full lawyer on me, like, 'I don't have to listen to you, I don't have to answer your questions.'"

Luckey said after that episode, she was "unfortunately not surprised" to learn Gaetz was facing a sex-trafficking investigation.

She also said she should have used the term "ephebophile" - a person attracted to mid- to late-adolescents - to describe Gaetz instead of "pedophile," a person attracted to pre-pubescent children.

Luckey said she recorded the videos to hold politicians accountable

"As someone who has personally experienced a ton of creepy old politician men hitting on me when I was underage and experiencing sexual assault at that age by people of power, it's just very disheartening," she said in the Monday video.

"While that little video I made was such a minuscule thing, and I know does not properly bring to light the whole situation, if I can just bring some attention to it ... and people can be held accountable, that's my goal."

When reached for comment by The Daily Beast, Ginger Luckey said: "Matt and I are enjoying our engagement and are deeply in love. My estranged sister is mentally unwell."

"She has been in therapy for years and our family hopes that after receiving in-patient mental health treatment, she will overcome the tendency she has repeatedly shown to engage in destructive behavior."
