Kluwe and Ayanbadejo filed an amicus brief to the United States Supreme Court on February 28, 2013, regarding "Hollingsworth v. Perry", in which they expressed their support of the challenge to California Proposition 8. Kluwe appeared on the January 18, 2013, episode of "The Ellen DeGeneres Show," to discuss his support of same-sex marriage. Ellen DeGeneres inducted Kluwe as the first inductee in her Hall of Fame, since NFL punters are unlikely to be voted into the league's hall of fame. On April 16, 2013, in recognition of his steadfast support of same-sex marriage and for starting a conversation about LGBT issues in athletics, Kluwe was named the Grand Marshal of the 41st annual Twin Cities Pride festival in Minneapolis, Minnesota.
