LOS ANGELES        -          “Kim Kardashian West: The Justice Project” will debut on the Oxygen cable network on April 5. The two-hour film will show West visiting prisons and working alongside legal experts on four cases of people they believe have been unfairly sentenced.

West is best known for developing beauty and fashion products and chronicling her life with her sisters on TV’s “Keeping Up with the Kardashians.” She became interested in criminal justice reform after helping to win the release two women from prison.

At a discussion about her new documentary, West was asked how she would respond to people who may think she had attached herself to the cause in order to burnish her well-known brand.

“I’m very used to criticism, so nothing really fazes me,” West said at the event organized by the Television Critics Association.

“I really genuinely just stay focused on the cases and the people,” she added. “I’m not doing it for publicity. I really do care.”

West, 39, said she works daily on her law studies for a total of 20 hours per week and just completed her first year of a four-year apprenticeship program in California. She is aiming to take the bar exam in 2022.

Her late father, Robert Kardashian, was a prominent Los Angeles lawyer who was part of the legal team that represented football star O.J. Simpson in his 1995 trial and acquittal for double murder.

Vince DiPersio, an executive producer of “The Justice Project,” said West was taking on a “fair amount of risk” by advocating for the release of prisoners.

“She is a nationally known figure and she has a big brand. God forbid someone gets out and does something terrible, but Kim is willing to take that risk,” he said.

In 2018, West successfully lobbied President Donald Trump to commute the life sentence of a 63-year-old Tennessee woman convicted of a first drug offense. In early 2019, she helped win clemency for another Tennessee woman who had been convicted as a teenager of murdering a man.

Some of the people featured in the documentary were brought to West’s attention by letters sent directly to her. She said she works on some of the cases herself and sends others to attorneys she believes can help.

The former Disney Channel star has been an A-list pop artist for roughly a decade.   In November, she landed her first No. 1 hit, “Lose You to Love Me,” a skyscraping ballad about letting go of a toxic relationship to save yourself.
