Kim Kardashian West made waves at the White House Wednesday.
The reality TV star personally met with President Trump, who tweeted out a smiling photo with Kardashian West in the Oval Office.
"Great meeting with @KimKardashian today, talked about prison reform and sentencing," wrote the president.
In their version of Twitter diplomacy, she later tweeted her thanks to the president.
Dressed in all black with bright yellow pumps, Kardashian West arrived at a security entrance with her lawyer, attorney Shawn Chapman Holley, late Wednesday afternoon.
During the meeting, which was set to include senior advisor Jared Kushner, Kardashian West advocated for the release of 62-year-old Alice Marie Johnson, who is serving a life sentence for a first-time, nonviolent drug offense, according to her post-meeting tweet. She has shared her support of Johnson on social media, calling the sentencing "so unfair" on Twitter in October.
She thanked the president and expressed hope he would "grant clemency to Ms. Alice Marie Johnson" after they met.
She added in a second tweet: "We are optimistic about Mrs. Johnson's future and hopeful that she — and so many like her — will get a second chance at life."
She continued her optimism in an interview with Mic Thursday, saying the president "really spent the time to listen to our case... I'm very hopeful."
She added her reasons why she believes Johnson is a good candidate for clemency, citing her good behavior in prison and a supportive family and job waiting for her back home.
She also commented on how Trump seemed during the meeting.
"The president seems to have a passion for everything that Jared has been trying to do," she said. "And that just makes me happy that that conversation is moving forward."
Earlier Wednesday, Kardashian West tweeted a birthday message for Johnson.
"Happy Birthday Alice Marie Johnson," she wrote. "Today is for you."
Johnson's story went viral thanks in part to a Mic video interview that reached more than 4.1 million views. A change.org petition asking President Trump to grant Johnson clemency has also almost reached its goal of 300,000 supporter signatures as of Wednesday.
Kardashian West, who cites Mic's video as how she discovered Johnson, has also helped the case reach a wider audience.
Kushner has focused on prison reform since joining the administration. He was involved with the First Step Act, which plans to expand programs for prisoners and allow for more home confinement. The act was approved by the House of Representatives earlier this month.
A pardon or commutation for Johnson is unlikely today, though the president has not made a decision.
Kardashian West supported Hillary Clinton during the 2016 presidential race, but recently, her husband Kanye West has tweeted his support for Trump.
The rapper met with Trump in December 2016 during a visit to the Trump Tower in New York. Trump posed with West after their meeting, calling him a "good man" with whom he talked about "life."
Kanye had previously declared his allegiance to Trump onstage the month prior.
