A gunman opened fire at Robb Elementary School in Uvalde, Texas on Tuesday, May 24, leaving a total of 19 children and two adults dead. The shooter was identified as 18-year-old Salvador Ramos and was killed by police at the scene. The tragic incident is the deadliest shooting at a U.S. elementary school since 2012's Sandy Hook Elementary shooting In Newton, Connecticut, which ended the lives of 20 children and six adults. This is also the 27th school shooting with injuries and the 212th mass shooting this year. As the nation mourns the lives of innocent people, celebrities are taking to social media to express their outrage over the lack of gun control in the country. President Biden has ordered U.S. flags to be flown at half-staff through May 28.

Celebrities from Texas like Matthew McConaughey and Selena Gomez have spoken out. Gomez linked off to Everytown, an organization working to end gun violence in America. "Those in power need to stop giving lip service and actually change the laws to prevent these shootings in the future," Gomez wrote. Artists from all over the country have also condemned the deadly attack including Taylor Swift, Britney Spears, Olivia Rodrigo, Lauren Jauregui, the Chainsmokers, and more.
