A key witness in former special counsel Robert Mueller’s Russia probe is getting a VIP escort to Virginia federal court — in the backseat of a vehicle belonging to one of the FBI case agents who helped secure his arrest on charges of kiddie porn possession.

Convicted sex offender George Nader will road-trip with at least two agents over concern about his heart condition, Brooklyn federal Magistrate Judge Cheryl Pollak said Tuesday.

“I feel much better releasing him into the custody of the FBI to transport him to the custody of the Eastern District of Virginia,” said Pollak following arguments regarding the 60-year-old’s serious heart condition. The drive will be recorded, she said.

The FBI escort was suggested by Assistant US Attorney Miriam Glaser Dauermann after Nader’s own lawyer Christopher Clark tried to convince Pollak to release his client on bail so an armed caravan could escort the ailing pedophile to his next court appearance.

Clark told the court his client had flown into New York City Monday to see a cardiologist at Mount Sinai, following open-heart surgery five weeks ago. He was arrested after landing at JFK.

“There are damaged vessels in his heart that were not repaired during his first surgery,” Clark said, noting any additional stress on his client could result in a heart attack.

A criminal complaint charging Nader with transporting material involving the sexual exploitation of minors was filed under seal in Virginia in 2018. The document details a dozen videos involving children as young as 3 — in some cases engaging in sexual activity with barnyard animals.

The sick materials were found on three iPhones belonging to Nader seized for unrelated reasons as part of the Mueller probe.

Nader has previous convictions for possessing child pornography and sexually abusing minors overseas.
