A 28-year-old Texas man is behind bars in Palm Beach County after authorities say he made antisemitic threats toward several conservative activists in Florida, including Laura Loomer.

According to the Florida Department of Law Enforcement, the investigation began Oct. 12 after agents were alerted to violent threats posted on X by a user going by “Klaus” under the handle @zionistarescum.

Investigators said the online posts, made between Oct. 8 and Oct. 10, targeted Joshua Benjamin Hammer, Seth Dillon, Karol Markowicz, and Loomer.

The affidavit detailed a series of messages containing antisemitic slurs and repeated calls for violence — including hanging, public beatings, and killing — while accusing the victims of being Israeli operatives or conspirators.

Florida Attorney General James Uthmeier is expected to address the arrest during a press conference in West Palm Beach on Tuesday.
