An earlier post by Brown went into more detail on the marches Saturday that drew hundreds of thousands of protesters in Washington, D.C., New York City and in every one of the 50 states, all calling for government action on gun violence.

\"March For Our Lives is an opportunity for us all to stand in solidarity against gun violence,\" the young actress wrote. \"No child, teen, parent or teacher should be afraid to walk into their school or classroom. This is our chance to be HEARD! This is our chance to MAKE A DIFFERENCE. This world needs to be filled with love, kindness and support of one another. No more fear, no more hurt, no more shootings, no more GUNS. To everyone participating in tomorrow’s March all over the country, you have my love, support, strength and encouragement! #MARCHFOROURLIVES #NEVERAGAIN @marchforourlives.\"
