Transcript for SCOTUS sides with student in case involving free speech on social media
Welcome back to "Gma." Now to the supreme court siding with that former cheerleader in a case that put free speech for students in the national spotlight. Terry Moran is here with the latest. Terry, good morning. Reporter: Good morning, whit. You know, sometimes here at the supreme court major cases come out of the halls of power, titanic clashes between congress and the president or business and government and then there are the others like this one where Pennsylvania cheerleader's disappointment turned into a landmark first amendment ruling. This morning, former cheerleader Brandi levy and student rights activists are celebrating. In an 8-1 decision the court ruled when they are school district suspended Brandi from the JV cheerleading squad for a post on snapcht they violated her first amendment rights. I went on Twitter and it said breaking news and I read it. I was like, oh, my god. Then I started -- I was yelling. Reporter: In 2017 Brandi was just 14, a freshman when she took to Snapchat to vent after failing to make the varsity cheer squad. I was angry and I made a post on snap. I said it was F school, F cheer, F softball, F everything. Reporter: That was posted off campus and on a Saturday but the coach of the cheerleading squad found out about it and the school banned her from cheerleading for an entire year. They told me that I'm lucky I didn't get expelled from school for it because it was vulgar language. Reporter: But with the help of her dad Brandi sued fighting their case all the way to the highest court in the land. You know, not that it was just a victory for Brandi and us, you know, but this is a victory for students and parents across the entire country. I think this is the most significant decision for young people's free speech rights in the past 50 years. Reporter: This is the first time the supreme court has considered that off campus student speech which is so common today with social media and the justices draw an older principles of law that students don't give up their first amendment rights when they go to school or are in school and schools have the right to regulate speech that disrupts the core educational mission or endangers other students and combran indy didn't do any of that. Key point, Terry, thanks so much. Story getting a lot of attention.
