The military will begin a year-long study to determine how to implement a possible repeal of “Don’t ask, don’t tell,” but the final decision to scrap the policy will be up to Congress, administration and military leaders told a Senate committee Tuesday.

Arkansas’ Democratic senators Mark Pryor and Blanche Lincoln said they wanted to hear more from military leaders before they decide how to vote on allowing openly homosexual people to serve in the armed forces.

Lincoln issued a statement Tuesday saying that she supported the current policy and would do so “until we hear from military leadership that a repeal can be achieved without a detrimental effect on unit cohesion, troop morale and military readiness.”
