A White House initiative promotes the stories of unsung and local leaders who are making an impact in the LGBT community.

The LGBT Pride Month Champions of Change Video Challenge was launched in April by the White House Office of Public Engagement. A group of finalists will be featured as Champions of Change at a White House event next month.

In one of the six videos nominated, viewers meet J.J. Kahle, who has led a Gay Straight Alliance at The Blake School in Minneapolis for the past 12 years.

“Her tireless advocacy and leadership of the GSA has helped transform Blake's environment into one where being homophobic is 'uncool,'” the video's description reads.

George Stewart is an 80-year-old volunteer and participant at the Harlem program of Services & Advocacy for GLBT Elders (SAGE) and at the recently opened SAGE Senior Center.

“The gay community is not into seniors so much. You have to be young, and all that stuff,” Stewart says in his video profile.

In another video, gay soldiers explain why they were moved to serve their country. (The video is embedded in the right panel of this video. Visit our video library for more videos.)
