The federal courthouse in Chicago stepped up security for a U.S. district judge after a possible threat against her.
The chief judge for the Northern District of Illinois issued a statement Monday afternoon saying a defendant may have made a threatening statement directed at Judge Sharon Johnson Coleman.
But Ruben Castillo didn't provide any details in the five-line statement.
Castillo's statement adds only that the court "takes all such threats seriously" and that the U.S. Marshals Service "will coordinate all necessary measures to ensure the safety and security of every judge."
The American Bar Association says Coleman was nominated by President Barack Obama and joined the federal bench in 2010.
