She and her attorney will lobby for the release of Alice Marie Johnson, who is serving a life sentence for first-time, nonviolent drug offenses committed in the early 1990s.
"It's not a serious thing to have happen here at the White House", Acosta said of Kardashian, who discussed prison reform with Trump.
During the White House press briefing Wednesday afternoon, White House press secretary Sarah Sanders wouldn't provide further details on who Kardashian was meeting, only saying, "She is expected to be here at the White House".
While it's not known how their meeting went and what the outcome will be, they both tweeted their thanks to each other, along with a picture of Kim stood behind the desk in the oval office, later on in the day.
West met with the then-president-elect at Trump Tower in NY in December 2016.
Should Trump grant clemency to Johnson, the decision would seem to mark a departure from his past statements, in which he has called for some drug dealers to receive the death penalty. After everyone in the room collectively gasped in disbelief over Wendy's diss, she said, "You come here to hear it straight, right?"
Johnson is now serving a life sentence in prison without parole after being convicted of drug-related charges in 1997. The case elicited widespread outrage when Brown was given a life sentence without eligibility for parole for 51 years.
"I would explain to [Trump] that, just like everybody else, we can make choices in our lives that we're not proud of and that we don't think through all the way", Kardashian West shared.
During the bitter 2016 election, Kardashian backed Trump's arch-rival Hillary Clinton.
Sandwiched in between tweets about her makeup line and cardio routine, Kardashian has been not-so-quietly advocating for criminal-justice reform.
Earlier this month, Kardashian opened up to Mic about her dedication to securing Johnson's freedom. Kardashian West appeared to preview the visit on her Twitter feed, writing: "Happy Birthday Alice Marie Johnson".
Kim Kardashian is meeting with that guy from the Apprentice at the White House Wednesday in an effort to secure a pardon for 62-year-old Alice Marie Johnson.
"We're grateful that Kim is using her platform to shine light on this issue", Ms. Barnett said in an interview. "Today is for you", adding the prayer hands emoji.
