Byron Donalds

A southwest Florida man has been arrested and charged after allegedly posting a death threat against Rep. Byron Donalds, R-Fla., following President Donald Trump's endorsement of the congressman for governor of the Sunshine State, WPBF News reported on Monday.

Dominic Ambrosia, 30, of Port Charlotte was taken into custody last week and charged with intimidation by written or electronic threat to kill or injure, according to court records filed in Charlotte County.

Authorities allege Ambrosia responded to a post on X on May 26 by writing, "I'm going to kill him! Thanks Mr. President."

The comment was allegedly made in response to Donalds sharing Trump's endorsement of his 2026 gubernatorial campaign.

Donalds, a Republican who represents Florida's 19th Congressional District, reposted Trump's message on X acknowledging the endorsement and thanking the president for his support.

According to court documents, law enforcement officials identified Ambrosia as the account holder who allegedly made the threatening post. The cops subsequently notified Donalds' security team.

Investigators said the congressman wished to pursue charges after being informed of the threat, WPBF reported.

Detectives later obtained account information from X, which allegedly linked the account to Ambrosia through a phone number associated with the profile.

Court records indicate investigators reviewed additional posts from the account and found what they described as concerning content, including reposts containing racial slurs directed at Black Americans and messages expressing opposition to Donalds becoming governor.

Authorities traced Ambrosia to a property in Port Charlotte, where he was reportedly living in a travel trailer located behind a residence.

On May 27, detectives contacted Ambrosia and received permission to search the trailer, according to court filings.

Investigators also discovered Ambrosia had a prior criminal history, including an arrest last year for aggravated stalking involving a neighbor.

Court records show Ambrosia was accused in that case of threatening to shoot his neighbor's dog and damaging the neighbor's mailbox and vehicle.

He later served some 300 days in the Pinellas County Jail and was released just over a month ago, according to court documents.

Authorities noted Ambrosia had been the subject of a threat assessment investigation that was suspended during his incarceration.

Court filings further state that while in custody, Ambrosia refused medication and denied having a mental illness.

In addition to the threat-related charge, Ambrosia was charged with failure of a convicted felon to register.

He remains held without bond in the Charlotte County Jail.

The case comes as political figures across the country have faced increasing security concerns amid heightened political tensions and a rise in threats directed at elected officials and candidates.
