We've been bringing you reports through the day on the battle in the Senate over the amendment on troop readiness offered by Sen. Jim Webb (D-VA).
The big news was that Sen. John Warner (R-VA) was going to offer a non-binding resolution to undercut the Webb Amendment. That was announced by Sen. John McCain (R-AZ) on the Senate floor and prompted a swift reaction from Webb, who had been negotiating with Warner but was apparently not told by Warner of his plan.
But now we're hearing that there may be more to this story. It's not clear whether McCain misspoke in saying Warner was the sponsor of the resolution, or whether Warner is now distancing himself from the resolution.
We're looking into it and will have more shortly.
Late Update: What doesn't appear to be in dispute is that Warner has announced he will not vote for the Webb Amendment, after originally supporting it. That is probably the most important takeaway from today's events, not whether Warner stabbed Webb in the back in the process of withdrawing his support for Webb's proposal.
Later Update: Our Greg Sargent is being told that the vote on the Webb Amendment and the GOP non-binding resolution is scheduled to occur in about an hour, at 5:15 ET.
