Diddy's Alleged 'Drug Mule' Given Immunity to Testify in Trial
Brendan Paul, Diddy's alleged "drug mule" -- who's been given immunity by Judge Arun Subramanian to testify in the music mogul's federal trial after confirming to the judge he's received a subpoena and intends to invoke the 5th Amendment -- took the stand in the federal trial Friday ... and the testimony is expected to revolve around drugs, TMZ has learned.
