After 3 years in the ROTC program at the University of North Carolina, Sara Isaacson told her commanding officer that she was a lesbian. She was immediately discharged from service and has now been asked to payback the $80,000 in tuition that the military paid for.She has gone public with her case in hopes of pushing the federal government and the military to repeal the "don't ask, don't tell" policy that has dictated how gays in the military are treated for the last 20 years.
