A defense attorney in the trial of a famous rapper asked Judge Ural Glanville on Wednesday to recuse himself from the case over allegations the judge tampered with a witness. Glanville denied his request on the spot.

It was the latest twist in Young Thug’s trial, which has transformed into a drama playing out in Georgia’s Fulton County Superior Court about allegations of a corrupt judge, the arrest of the rapper’s attorney, and the prospect of a mistrial in a complex racketeering case eating up enormous public resources.
