WASHINGTON (CNN) Sen. John Warner, R-Virginia, and six other Republican senators who oppose the troop increase in Iraq, sent a letter to Senate Democratic and Republican leaders Wednesday afternoon saying the "current stalemate" over the Iraq resolutions is "unacceptable" and they intend to offer the Levin-Warner resolution "disagreeing" with the increase in troops to future bills coming before the Senate.

"We strongly believe the Senate should be allowed to work its will on our resolution as well as on the concepts brought forward by other senators," Warner said on the Senate floor, reading from the letter. "Monday's procedural vote should not be interpreted as any lessening of our resolve to go forward advocating the concepts" of the resolution.

In addition to Warner, GOP Sens. Susan Collins of Maine, Gordon Smith of Oregon, George Voinovich of Ohio, Olympia Snowe of Maine, Chuck Hagel of Nebraska, and Norm Coleman of Minnesota all signed the letter.
