After threatening this morning to hold a procedural vote on the bill containing repeal of Don’t Ask Don’t Tell, Senate Majority Leader Harry Reid’s office confirmed late Wednesday that he will postpone the vote as negotiations continue with Republicans who support lifting the ban on gays and lesbians serving openly in the military.
The Senate will also not hold a test vote on the DREAM Act tonight.
The delay will allow more time for Reid to negotiate with Republican Sen. Susan Collins, who supports repeal but has demanded a "fair and open" process on debate and amendments to the Defense Authorization bill that contains the DADT repeal.
Shortly before the postponement was made public, Republican Sen. Susan Collins said she would not vote to bring the bill containing Don't Ask, Don't Tell to the floor if it the vote happened tonight.
"Everyone on the Republican side wants to see the tax package completed first," Collins said in a nod to the GOP caucus's promise to block legislation until the Senate addresses the Bush-era tax cuts or government spending. "So I have urged the Majority Leader to postpone the vote ... which he is threatening to hold tonight so we could get the tax bill considered first."
"Why not take the path that would lead to 60 votes?” Collins asked.
During negotiations Wednesday, Reid made an offer to address Collins' concerns, proposing to allow Republicans votes on 10 amendments and up to 17 hours of debate on the bill.
Collins rejected that deal.
Collins said she made a counter offer, requesting double the time for debate and more freedom for Republicans to choose the amendments they address.
But when asked what Reid's response was, Collins said "he does not seem interested at this point."
"There are many people in my caucus who disagree with my position [to repeal DADT],” Collins told reporters. “They deserve an opportunity to offer amendments to strike that provision, to modify it, and also to address other important controversial issues in the bill."
