The Chairman of the Joint Chiefs of Staff supports the repeal of the military's ban on gays but he doesn't think the Congress should be in a rush to vote on it. Admiral Mike Mullen was critical Sunday of Congress' attempt to pave the way to dismantle to law.

"Ideally, I would have certainly have preferred that legislation not be brought forward in terms of the change until we are completed with that review," Mullen told CNN's Candy Crowly.

"The Congressional clock is sometime pretty difficult to predict. And certainly the votes last week indicate that it's moving but in terms of when it possibly might change, that's really not done. The thing that the language does permit, it permits myself, Secretary of Defense and the president to certify. And that certification is key in terms of when this -- when we would be ready to implement it and whether in out judgement how much the change is going to affect the things are on the top of the list for me including readiness, unit cohesion and recruiting retention," Mulled explained.

"So, all that is very much still in play in ways it makes this review and collecting the information and understanding what's going on at the deck plate level from our troops and in our families that much more critical," he said.
