On March 14, students from across the country participated in the National School Walkout to commemorate the tragic Valentine's Day shooting in Parkland, Florida.

#NationalWalkoutDay

Throughout the day, millions of students braved the elements to memorialize the 17 people who tragically lost their lives at Marjory Stoneman Douglas High School. All of the students that participated in this epic walkout dropped whatever they were doing around 10 a.m. and left their classrooms to raise their voices against gun violence.

According to CNN, students who participated in this monumental walkout wanted Congress to do three things. First, they wanted the nation's leaders to ban assault weapons. Second, the student activists wanted Congress to pass a law that would allow courts to disarm people who showcase disturbing behavioral patterns of a future shooter. Finally, the students demanded that both the U.S. House of Representatives and the U.S. Senate create a law that would require anyone who is interested in purchasing a firearm to pass a universal background check.

The Celebrities' Reaction

Celebrities spoke out in droves commending the students for taking responsibility and voicing their opinions. Among the celebrities who spoke out were iconic performers, fan-favorite creators, and various recording artists. Josh Gad, whose family friend's son was tragically killed during the Feb. 14 massacre, also spoke out. The Frozen voice actor previously vowed to support anti-National Rifle Association candidates and hoped to educate others on gun control following the attack.

"So unbelievably proud of these students. So blown away by their unstoppable energy and their devotion to hold our legislators accountable. They are not going away, but those officials who do nothing to reform gun laws, most certainly will be," tweeted Gad.

Former coach of The Voice, Miley Cyrus, also joined the chorus. The outspoken "Wrecking Ball" singer shared an Instagram clip with a girl carrying a sign that read: 'Protect Kids NOT Guns.' to her 40 million Twitter followers.

"Proud of all of you! Never Give Up! You are THE change! So amazing to see young people take back their power and USE it," wrote Cyrus.
