In a series of tweets sent on Sunday, the 35-year-old reality star called out Congress for failing to close the "terror gap," a legal loophole that allows individuals on terrorist watch lists to purchase firearms.
Kim has spoken openly about gun laws in the past.
Following the 2012 mass shooting at Sandy Hook Elementary School in Newtown, Connecticut -- which left 26 people, mostly children, dead -- she tweeted her support of stricter gun control. In June 2015, she also offered gun control as an idea that could change the world during a Q&A session hosted by the Commonwealth Club of California.
"I’m not the type to have them in my house. They scare me so much,” Kim said at the session, adding, “I’m not really a gun person, and we do not have strict enough gun control laws.”
The "Keeping Up with the Kardashians" star echoed that sentiment in August with another series of tweets. She asked followers if they'd heard of David Conley, a man who allegedly murdered his ex-girlfriend Valerie Jackson along with her common-law husband, Dwayne Jackson, and six children with a gun purchased online.
Kim's continued push for gun control represents a more socially conscious side of the reality star. Over the past year, she's used her platform to call attention to other serious issues including the controversial death of Sandra Bland and the importance of mental health in an age of social media.
