Army Lieutenant Dan Choi, one of the most visible opponents of “don't ask, don't tell,” was arrested while protesting the policy Thursday outside the White House, gay blog AmericaBlog.com first reported.

Choi was discharged from the Army last year after he announced he was gay on MSNBC's The Rachel Maddow Show.

After speaking at a DC event hosted by the Human Rights Campaign (HRC), Choi, along with Capt. Jim Pietrangelo and a large crowd, marched to the White House, where the men handcuffed themselves to the fence.

At the HRC event, which included comedian Kathy Griffin, Choi announced: “Our fight is not here at Freedom Plaza, it is at the White House. We are walking to the White House right now to send the President a message. So, take out your cell phones and your cameras. Document this moment. Join us as together we make history.”

President Obama has called for repeal of the policy that bans gay troops from revealing their sexual orientation. Both chambers of Congress have introduced legislation that would repeal the 1993 law.

Opponents of repeal say the law is needed to keep good order and discipline among the ranks. A near universal majority of Americans say the policy is discriminatory and a majority say it should be scrapped.

The crowd, estimated in the hundreds, applauded the men as they were hauled away.
