Jon Christopher Enriquez was sentenced to 24 months behind bars after pleading guilty to three counts of transmitting threats through interstate communications, according to the U.S. Attorney's Office for the Southern District of Florida.

Prosecutors said Enriquez published the threats on X on May 27, spread across three separate public posts over the course of a single afternoon. The posts threatened that Secretary of State Marco Rubio and former State Department Special Envoy Kristi Noem would be executed at specific times, according to a Justice Department news release.

"Anyone who believes they can hide behind a keyboard while threatening to kill our nation's leaders should think again," Acting U.S. Attorney Yara Lorenzo Klukas said in a written statement. "These are not harmless words. They are serious federal crimes with serious consequences. We will work relentlessly with our law enforcement partners to identify, prosecute, and bring to justice those who make such threats."

The case is the latest in a string of federal prosecutions targeting political violence and intimidation carried out online. Federal law treats threats transmitted across state lines as crimes regardless of whether the person making them has the means or intention to carry them out, a standard prosecutors have applied with increasing frequency as public officials face a surge of harassment on social media.

Rubio, a former Florida senator, now serves as the nation's top diplomat. Noem previously held the role of special envoy at the State Department.

Enriquez's sentence was handed down in federal court in South Florida. Court records did not indicate whether he had an attorney who could comment on the sentencing.
