A lot of folks were not happy about who sang the national anthem at the NBA finals the other night. 11-year-old Sebastian de la Cruz is known for having a golden voice. He nailed the national anthem at the NBA finals on Tuesday, but the poor kid was faced with internet backlash. Twitter and Facebook were full of racist comments. Sebastian says he thinks it was his mariachi outfit that sparked most of the comments. He also says he`s not letting racist comments get him down; he`s proud to be a mariachi singer.
