Majority leader Reid agreed to allow the Warner-Levin, McCain-Lieberman, and Gregg resolutions on the floor for an up-or-down vote, or alternately the first two for a 3/5 majority.

Thus, the Senate still has to vote on whether or not to allow the debate to proceed.
Vote will be completed in a few minutes. Stay tuned....
