One of the men he accused in the plot, Bob Kent, denied the accusations on Monday.
Kent said he wasn't trying to extort the Gaetzes but wanted a loan to help free a missing American.
Rep. Matt Gaetz of Florida has said that the accusations surrounding his Justice Department sex-trafficking investigation were false smears used in an extortion attempt.
Now, one of the men whom Gaetz accused of extortion, the former Air Force intelligence officer Bob Kent, is denying the claim, saying he was trying to ask Gaetz's father for money to help free an American in Iran.
In interviews with CNN's Chris Cuomo and SiriusXM personality Michael Smerconish on Monday, Kent said he was not responsible for Gaetz coming under scrutiny in the first place and said he had nothing to do with the sex-trafficking investigation.
