President Obama's commitment on ending DADT

Second Lieutenant Sandy Tsao sent a letter to President Obama asking him to repeal the Don't Ask, Don't Tell policy. She received this in return:

Sandy -
Thanks for the wonderful and thoughtful letter. It is because of outstanding Americans like you that I committed to changing our current policy. Although it will take some time to complete (partly because it needs Congressional action) I intend to fulfill my commitment.
— Barack Obama
