Kim Kardashian is reportedly working to free another prisoner following the successful pardon of convicted great-grandmother Alice Marie Johnson.

The reality star appeared on Jason Flom’s Wrongful Conviction podcast on Wednesday (05Sep18) and, in an exclusive preview obtained by Page Six, revealed that she has been in talks with the White House and is working to free Chris Young, who was sentenced to life in prison for drug possession after being arrested in 2010.

"Yesterday, I had a call with a gentleman that’s in prison for a drug case - got life. It’s so unfair. He’s 30 years old. He’s been in for almost 10 years," the Keeping Up with the Kardashians star shared.

Kim went on to explain that Chris had been sentenced to life without parole for possession of marijuana and half a gram of cocaine due to mandatory-sentencing regulations.

She added that she already had the support of former Tennessee Judge Kevin Sharp, who had originally sentenced Chris but had later resigned over being "forced" to deal out such a harsh sentence.

"I was on the phone with the judge that sentenced him to life, who resigned because he had never been on the side of having to do something so unfair, and now he is fighting (alongside) us to get (Chris) out," the mum-of-three shared.

In addition, Kim said she holds regular talks with U.S. President Donald Trump's son-in-law and aide, Jared Kushner, who she insisted is "passionate" about changing sentencing laws.

In June, Kim convinced the president to pardon Alice Marie Johnson, who had received a life sentence following a 1996 conviction for a non-violent, first-time drug offence, in which her only role was answering phones. The 63-year-old was released after serving 22 years behind bars.
