*Rap star T.I. is due before a federal judge in Atlanta to explain why his probation shouldn’t be revoked after his recent arrest in Los Angeles.

U.S. District Judge Charles Pannell Jr., the same judge who sentenced T.I. for firearms violations, signed the summons for the rapper on Thursday, reports the AP.

The order lists three possible violations of his bond: possession of ecstasy, testing positive for opiates and associating with a convicted felon.

Pannell did not set a date for the hearing.
