(CNN) Kim Kardashian West is taking her fight for those she believes have been wrongly convicted to death row.

Kardashian West went to California's San Quentin State Prison to meet with Kevin Cooper, who has been on death row since he was convicted of killing two adults and two children in 1983.

"I had an emotional meeting with Kevin Cooper yesterday at San Quentin's death row," she tweeted . "I found him to be thoughtful and honest and I believe he is innocent of the crimes for which he was convicted."

She followed up her tweet with another that read, "I am hopeful that Kevin will be exonerated since DNA testing has now been ordered on Kevin's case and I remain grateful to Governor Newsom for ending capital punishment in California."

In October, Kardashian West asked then-California Gov. Jerry Brown to look into Cooper's case because she believed he had been framed. She also asked the governor to order a DNA test. Brown ordered the tests late last year, and the state's new governor, Gavin Newsom, has since ordered additional testing.
