Chloe Cole will head up a rally outside the Supreme Court on Wednesday morning as justices hear arguments in a case related to transgender procedures for minors. 

Cole became known for documenting her own transition journey online, which began at the age of 12 when she became a boy. Six years later, Cole transitioned back to a female. She testified about her ordeal, which included a double mastectomy as a teenager, when she spoke before Congress last year.
