Why this 14-year-old activist is fighting for the rights of trans athletes

Lawmakers in more than 28 states have proposed legislation to ban transgender athletes from participating on sports teams that match their gender identity at the youth, high school and collegiate level. In New Jersey, where trans athletes have protections, 14-year-old Rebekah Bruesehoff is fighting for the rights of transgender kids — while attending school and playing on her field hockey team. Here's her story, as told to CBS News' Zoe Christen Jones. 

There are so many things that make me, me. Some are my smile, my laugh, and the way I care about things. I'm 14 years old, and my mom says she loves the way I'm full of joy. I'm also a total nerd and a straight-A student. I play clarinet in the band, love to write and one of my favorite things to do is play field hockey. I'm also transgender but that's just one part of who I am.
