Negotiations are ongoing, the aide told TPM, with Lieberman and Reid continuing to reach out to Collins with the hope that she'll take something less than unlimited debate to secure her cloture vote and, with it, the likely end to Don't Ask, Don't Tell.

The Democratic aide did not say if a cloture vote fail tonight would mean Reid and others would strip out DADT from the defense bill for a final vote on military funding, as some have predicted.

Collins' office did not immediately respond to a request for comment.
