Responding to a federal judge's order late last week, prosecutors on Wednesday identified U.S. District Judge Michael Davis and members of the FBI's Joint Terrorism Task Force as the subjects of threatening tweets allegedly posted by a 20-year-old Minneapolis man last year.

Khaalid Adam Abdulkadir, charged with making the threats, did not name anyone in tweets he allegedly sent after his friend, Abdirizak Warsame, was arrested and charged in December with providing material support to the Islamic State of Iraq and the Levant (ISIL).

But prosecutors noted that Davis has presided over the bulk of cases involving defendants conspiring to travel and fight for ISIL. They have also said that the number of FBI agents investigating the cases has been "discrete."

Abdulkadir allegedly tweeted "More brother get locked up the cops body they will find on the floor body's dropping fast #kill them FBI and [expletive] as judge." Another tweet read: "[Expletive] them F.B.I. I'm kill them FEDS for take my brothers."

The tweets were deleted shortly after being posted, but an informant shared screen shots of them with the government, according to documents filed in court. Abdulkadir has since been indicted on charges of threatening to murder a federal judge and federal agents, and interstate transmission of a threat. Last week, a judge ordered prosecutors to specify who was threatened before the case could proceed.

Abdulkadir has been in custody at the Sherburne County jail as he awaits a March trial. Earlier this month, Warsame became the fourth defendant to plead guilty to providing material support to a designated foreign terrorist organization and awaits sentencing. Five others are scheduled to stand trial in May.
