Florida lawmaker claimed hitman made threat against him on Twitter
“I think someone may be trying to kill me. If they are successful, I would like my constituents and my family to know who stopped their arrest,” said Mr Gaetz on the floor of the House.
The Republican claimed that the Capitol Police had recommended that the individual in question be arrested, but that the Department of Justice had refused to do so.
It is the latest in a string of bizarre events surrounding the pro-Trump congressman.
Mr Gaetz is the subject of a federal investigation that has seen his associate, Joel Greenberg, the former tax collector of Florida’s Seminole County, take a plea deal for multiple federal crimes, including sex trafficking of a minor and introducing her to other “adult men” who also had sex with her when she was underage.
Greenberg, a close friend of Mr Gaetz, pleaded guilty to six charges in May and is still cooperating with investigators.
Mr Gaetz has strongly denied any wrongdoing and has not been charged with any crimes.
In March the Justice Department charged a Wyoming man of making death threats to Republican politicians, including Mr Gaetz.
Christopher Podlesnik, 51, was charged with making threats against Mr Gaetz on 28 januar, the same day he took part in a rally against Representative Liz Cheney in her home state of Wyoming.
