Dan Choi

Choi served as an Army guardsman with the 1st Battalion, 69th Infantry, based in Manhattan.

Choi received a discharge letter following his coming out on The Rachel Maddow Show.

In response, Choi penned an open letter to U.S. President Barack Obama and the United States Congress.

In the letter, Choi challenged the morality and wisdom of Don't Ask, Don't Tell, writing that the policy is "a slap in the face to me. It is a slap in the face to my soldiers, peers and leaders who have demonstrated that an infantry unit can be professional enough to accept diversity, to accept capable leaders, to accept skilled soldiers."

Dan Choi (born February 22, 1981) is an American former infantry officer in the United States Army who served in combat in the Iraq War during 2006–2007.

Since Choi's coming out, 38 West Point alumni also came out and announced the formation of Knights Out, an organization of West Point alumni who support the rights of LGBT soldiers to serve openly.

He became an LGBT rights activist following his coming out on The Rachel Maddow Show in March 2009 and publicly challenged America's Don't Ask, Don't Tell policy, which forbade lesbian, gay and bisexual (LGB) service members from serving openly.

Despite his appeal and a Courage Campaign petition signed by almost 162,000 people, on June 30, 2009, a panel of New York National Guard officers recommended that Choi be discharged from the military.

In the episode, Choi criticizes the U.S. military's neglect of the partners of service members.

On October 19, 2010, Choi applied to rejoin the US Army.

As of February 2010, Choi was serving again in his Army National Guard unit, the discharge having not yet been "finalized".

On June 29, 2010, Choi's discharge was finalized.

In February 2010 Choi was selected to be a Grand Marshal of the 41st Annual New York LGBT Pride March by its producers, Heritage of Pride.

At the event, Choi led the Pledge of Allegiance at the New York City Council Chambers.

On March 18, 2010, Choi and another ousted military officer, Capt. Jim Pietrangelo, handcuffed themselves to the fence of the White House.

They were eventually removed with the use of a master handcuff key and arrested.

Choi and Pietrangelo were initially set to be tried for "failure to obey a lawful order" on April 26, 2010.
