The full U.S. House Armed Services Committee approved three amendments late Wednesday night that seek to delay implementation of repeal of Don't Ask, Don't Tell and to reiterate Congress's support for the Defense of Marriage Act.

The votes were largely along partisan lines and are unlikely to be sustained in the Democratic-controlled Senate, even if they are approved by the Republican-dominated House.

But the question is whether they might survive a Senate-House conference committee, when compromises have to be hammered out between two increasingly contentious parties.
