A key Senate committee has agreed to hold a hearing on repeal of the military's ban on open gay and lesbian service in the fall.

New York Senator Kirsten Gillibrand made the announcement in a statement Monday.

The Senate Armed Services Committee will hold the hearing, Gillibrand, a Democrat, announced.

“This policy is wrong for our national security and wrong for the moral foundation upon which our country was founded,” the freshman senator said.

The military's ban on open gay service, also known as “don't ask, don't tell,” mandates discharge for gay and lesbian service members who do not remain celibate or closeted. According to the Servicemembers Legal Defense Network (SLDN), a group that lobbies for repeal of the law, 320 soldiers have been fired under President Obama's watch.

“Numerous military leaders are telling us that the times have changed,” Gillibrand added. “'Don't ask, don't tell' is an unfair, outdated measure that violates the civil rights of some of our bravest, most heroic men and women. By repealing this policy, we will increase America's strength – both militarily and morally.”

Candidate Obama pledged he would repeal the law, but President Obama has refused to consider ending discharges with an executive order, saying only Congress can rein in the law.

Approximately 13,000 service members have been fired for being gay since the policy was enacted in 1993.
