Joint Chiefs of Staff Chairman Admiral Mike Mullen is insisting that the Marines will follow orders if “Don't Ask, Don't Tell” is repealed.

Marine Commandant General James Amos' public objections to repeal of the law that forbids gay and bisexual troops from serving openly “surprised” Mullen. But in an interview Sunday on CNN's State of the Union, Mullen insisted that there is “no question” that Amos would fully cooperate if Congress lifted the ban.

“He said, 'if this law changes, we are going to implement it and we are going to implement it better than anyone else,'” Mullen said of Amos.

Amos told the Los Angeles Times two weeks ago that repeal involved “risk.”

“There's a risk involved,” Amos, who recently assumed the helm from retiring General James Conway, said. “I'm trying to determine how to measure that risk. This is not a social thing. This is combat effectiveness.”

Conway also strongly objects to repeal of the 17-year-old law. “90 to 95 percent of the Marines” are against repeal, he told Fox News, citing impromptu surveys he had conducted by a “show of hands” at town hall meetings.

Democratic leaders have pledged to put repeal up for a vote after the Thanksgiving break. Senator Joseph Lieberman (I-Conn.) said last week that he has more than the 60 votes needed for repeal. GOP Senators Lisa Murkowski of Alaska and John Ensign of Nevada have signaled that they're leaning toward a “yes” vote on repeal of the law that has ended the military careers of more than 13,000 service members.
