R. Kelly’s legal team is demanding his emergency release from federal prison, claiming the embattled R&B singer was given an “overdose quantity” of medication by prison staff at Butner Federal Correctional Institution in North Carolina, leading to his hospitalization on June 13.

According to a June 17 court filing obtained by USA TODAY, Kelly—born Robert Sylvester Kelly—was placed in solitary confinement on June 10, just days after filing a motion alleging a murder-for-hire plot involving prison officials and a white supremacist gang member. Two days later, his attorneys say he was instructed to take an unusually high dosage of his anxiety and sleep medication, resulting in him collapsing and losing consciousness in his cell.

Prison staff were reportedly unable to treat him onsite, and he was taken to Duke University Hospital, where he remained for two days. Kelly’s attorneys allege he was discharged “against medical advice” and further claim he’s being denied essential blood-thinner medication and a surgery to address blood clots in his legs and lungs.

The Bureau of Prisons declined to comment on ongoing litigation.

Federal prosecutors responded sharply, calling Kelly’s latest claims an attempt to manipulate the court and cast himself as a victim. “This is the behavior of an abuser and a master manipulator on display,” the response stated, adding that Kelly’s legal team filed in a court without jurisdiction and exaggerated the conditions of his confinement.

Kelly, 58, is currently serving a 30-year prison sentence after being convicted in 2021 on nine federal charges, including racketeering and sex trafficking. The charges stemmed from decades of abuse allegations involving underage girls and coercive control. He also faces additional charges in Illinois and Minnesota.

This is Kelly’s third attempt at seeking a furlough from prison due to alleged threats to his life. His legal team now argues that his survival depends on being transferred to home confinement.
