After a federal judge unsealed documents related to the FBI’s search of former US president Donald Trump’s Mar-a-Lago residence in Florida, fears have grown over increased threats of violence.

Magistrate Judge Bruce Reinhart unsealed the search warrant and attachments Friday, following a motion Thursday from the Department of Justice (DOJ). Since unsealing the documents, Reinhart has become the target of violent and anti-Semitic threats, with his personal information, including home address, shared across Twitter and far-right platforms. Threats against Reinhart have prompted the federal judiciary to renew calls for Congress to pass legislation aimed at increasing security for judges.

According to the unsealed documents, the FBI seized 11 sets of classified documents. They also revealed that the DOJ is investigating Trump for violating federal laws. Trump has said that the documents were declassified.

Media outlets have confirmed that the FBI and Department of Homeland Security released a joint intelligence bulletin Friday noting an increase in threats against FBI officials. On Saturday, armed protesters gathered outside the FBI offices in Phoenix, Arizona, ultimately dispersing without incident. Earlier last week an individual was killed after attempting to enter the FBI office in Cincinnati, Ohio, armed with an AR-15 style rifle and a nail gun.
