The Keeping Up With The Kardashians star weighed back in to the debate later in the day with a series of tweets expressing outrage at America's lack of gun regulation.
"Under current federal law people on terror watch lists can legally buy guns -- this is called the Terror Gap," she wrote. "We have repeatedly called on Congress to close this loophole that makes it easy for dangerous people to get guns & kill. Nothing has changed!!!! People continue to senselessly die. When will these gun laws be changed?!"
Under current federal law people on terror watch lists can legally buy guns – this is called the Terror Gap
According to the Everytown for Gun Safety website, an organization working towards ending gun violence, a bill to close the terror gap loophole was blocked in the Senate in December 2015.
Kardashian retweeted others expressing similar sentiments, including one from popular YouTuber Troye Sivan about Australia's successful response to a mass shooting by enacting gun control measures. In that case, a shooter killed 35 people in a small Tasmanian town with an AR-15 rifle, the same make as reportedly used in the Orlando shootings this weekend, as well as in other recent mass shootings in the U.S.
The fact that someone on the FBI's watch list was able to purchase firearms legally tells you just how flawed the system is.
This isn't the first time the 35-year-old reality star has made her thoughts on gun control well known on social media. Last year, Kardashian took to Twitter after it emerged that David Conley, a man who fatally shot his ex-wife, her six children and her husband, was able to buy the ammunition he used in the shootings online.
Other celebrities have also come out in favor of stricter gun laws. Notably, Amy Schumer made an emotional speech against gun violence after a man opened fire last year during a screening of her movie, Trainwreck, killing two women.
