The case had been assigned to Royce Lamberth, who stepped down in July as chief judge of the District Court in Washington, D.C.
Mandatory retirement laws forced Lambert to quit in July after he turned 70. See Washington Post story about his tenure.
The court sent the Velázquez case to its calendar committee, where I presume it will be reassigned to another judge.
See details of the Velázquez indictment here.
