The Washington state chapter of the American Civil Liberties Union, which represents Maj. Margaret Witt of Spokane, says she flew to Washington, D.C., on Tuesday and will attend the ceremony Wednesday.
Witt says she's excited to be there for all of the people who can't attend.
Witt was discharged just short of retirement after the Air Force learned she had been in a relationship with a civilian woman. She sued, and in September a federal judge found her dismissal was unconstitutional because it advanced no legitimate military interest.
She expects to rejoin the Air Force Reserve early next year.
