leaked results of a Pentagon survey that reportedly says most troops support repealing the policy.

"We'll have this report done here and to Secretary Gates in the next couple of weeks by December 1st, and I won't make any comments on where I think we need to go until that report is done," he said.

But Mullen made it clear that he supports repeal. "From my personal perspective, absolutely."

"I think it belies us as an institution. We value integrity as an institution," Mullen continued.

"Asking individuals to come in and lie about who they are every day goes counter to who we are as an institution."

Mullen expressed concern about the head of the US Marine Corps, who said it was the wrong time to overturn the ban on gays serving openly.

"There's risk involved; I'm trying to determine how to measure that risk," Gen. James Amos said at the beginning of November. "This is not a social thing. This is combat effectiveness. That's what the country pays its Marines to do."

"What concerned me about his most recent comments, it came at a time where we actually had the draft report in hand, and we had all agreed that we would speak to this privately until we completed the report and made our recommendations up the chain," Mulled said.

But the Join Chiefs chairman is confident that Amos will comply should the "don't ask, don't tell" policy be repealed.

"He basically said that if this law changes, we are going to implement it, and we are going to implement it better than anybody else," Mullen told CNN's Candy Crowley Sunday.
