Amanda Blackhorse Amanda is a social worker, plaintiff in Pro Football vs. Blackhorse and advocate for Native issues and rights.

Amanda Blackhorse is Dine’ and a member of the Navajo Nation. Amanda is from Big Mountain and Kayenta, Arizona. In June 2014, Amanda Blackhorse and four other young Native American petitioners, organized by Suzan Shown Harjo, won their 9 year long case before the Trademark Trial and Appeal Board under the US Patent Office in Blackhorse vs. Pro Football to cancel the federal registrations of the NFL team, the Washington R*dsk*ns. As a result, Pro-Football sued Amanda and her co-plaintiffs. On July 8, 2015 a federal judge upheld the TTAB decision to cancel the teams registrations on the grounds of disparagement – the team lost their appeal. Pro Football appealed once again and the case is currently making its way through the fourth circuit court of appeals. Amanda also speaks nationally about how colonization and historical trauma contribute to the legacy of Native American mascots.
