A Minneapolis special education teacher has been put on “paid administrative leave” after posting a threatening tweet about Supreme Court Justice Brett Kavanaugh.

The tweet was sent Saturday — the same day Kavanaugh was confirmed by the Senate and sworn in following a contentious confirmation fight. According to the Star Tribune, a teacher from Intermediate School District 917’s Alliance Education Center tweeted: “So whose [sic] gonna take one for the team and kill Kavanaugh?”

The teacher’s Twitter account has since been deleted, but the content was reported to the FBI and Secret Service before it was removed. The Star Tribune said it would refrain from identifying the teacher, since the teacher has not yet been charged.

ISD 917 superintendent Mark Zuzek confirmed that an employee was put on administrative leave.

“Over the weekend, the district has received a complaint regarding an employee. The employee has been placed on paid administrative leave pending the outcome of the investigation,” Zuzek wrote in a statement. “Pursuant with the data practices act, we are limited to providing additional information regarding this matter.”

It remains unclear which law enforcement branch will investigate the tweet, since the FBI and the Secret Service were first alerted, but the U.S. Marshals Service is required to defend the federal judiciary.
