Reality TV star Kim Kardashian West has revealed in an interview with Vogue that she is going to take the bar exam to become a lawyer.

Kim played a role in the release last summer of Alice Marie Johnson, a 63-year-old woman who’d been in an Alabama prison on a nonviolent drug charge since 1996, and whose case Kim had learned about through social media.

Kardashian, who has Armenian roots, has been working with Jones and the attorney Jessica Jackson, cofounders of #cut50, a national bipartisan advocacy group on criminal-justice reform, for months, visiting prisons, petitioning governors, and attending meetings at the White House.

And last summer, she made the unlikely decision—one she knew would be met with an eye roll for the ages—to begin a four-year law apprenticeship, with the goal of taking the bar in 2022.

“I had to think long and hard about this,” she says. What inspired her to embark on something so overwhelmingly difficult and time-consuming—even as she also runs a multimillion-dollar beauty enterprise—was the combination of “seeing a really good result” with Alice Marie Johnson and feeling out of her depth.

“The White House called me to advise to help change the system of clemency,” she says, “and I’m sitting in the Roosevelt Room with, like, a judge who had sentenced criminals and a lot of really powerful people and I just sat there, like, Oh, shit. I need to know more. I would say what I had to say, about the human side and why this is so unfair. But I had attorneys with me who could back that up with all the facts of the case. It’s never one person who gets things done; it’s always a collective of people, and I’ve always known my role, but I just felt like I wanted to be able to fight for people who have paid their dues to society. I just felt like the system could be so different, and I wanted to fight to fix it, and if I knew more, I could do more.”
