Last year, the Justice Department quietly closed the inquiry into Mr. Gaetz after investigators concluded they could not make a strong enough case against him in court, people familiar with the matter said.
Mr. Scheller said the documents he handed over to Congress came in response to a request from the House Ethics Committee.
A spokeswoman for Mr. Gaetz, Jillian L. Wyant, said on Friday that the Justice Department had received the same material as that sent to the Ethics Committee and “deemed it unreliable and declined to press charges.” The news media, she added, “should not be laundering smears from people in prison.”
It is unclear how useful the documents will be to the committee, which began its investigation into Mr. Gaetz several months ago, after concluding one into George Santos, the former New York representative who had fabricated large portions of his background as he ran for Congress. The House expelled Mr. Santos late last year, after the committee released its report.
The investigation of Mr. Gaetz has been slow moving as investigators have been sent a range of tips. Mr. Gaetz has claimed that the inquiry is in retaliation against him for taking the lead in ousting Kevin McCarthy as House speaker.
