Kourtney Kardashian joined other celebrities on Saturday to speak out against gun violence, which claimed several lives at a Texas school recently.

The reality TV actress, who recently married, took to Instagram to share a screenshot of Gigi Hadid’s anti-gun violence post as well as a donation request for an organization trying to reduce gun violence.

Meanwhile, on Saturday, Texas investigators were attempting to determine how significant errors were made in the reaction to the tragic Uvalde shooting, including why nearly 20 police officers stayed outside a primary school classroom while children dialed 911 for aid.
