Army Lt. Dan Choi's life was changed forever by three words: "I am gay."

Choi made the revelation in 2009 on The Rachel Maddow Show, and soon after, the soldier was notified by the U.S. Army of upcoming discharge proceedings against him.

A West Point graduate, war veteran and now former U.S. Army lieutenant, Choi today is an activist, advocating for LGBT civil rights and veterans' health. This spring, he spoke at UNT as part of the Distinguished Lecture Series, addressing students about his work that led to the eventual repeal of the military's "Don't Ask, Don't Tell" policy.

Students also participated in a Q&A session with Choi, who served as an Arabic translator in the U.S. Army in Iraq from 2006 to 2007. He joins a growing list of world-class speakers invited to UNT for the series, which aims to introduce students and the UNT community to people from diverse backgrounds and enhance learning.
