Those comments have the potential to dramatically slow down congressional consideration of a resolution authorizing the use of force. Senate Democrats on Monday night already put the brakes on consideration of Syria language, and are now expected to set up a procedural vote by Wednesday at the earliest.

But even that could change if Russia and Syria can find a way forward on a chemical weapons deal that satisfies the United States. One possibility is that no congressional votes are needed at all; another is that Congress could decide to consider new language that takes into account any agreement that is reached on chemical weapons.

A third possibility is that a negotiated settlement remains out of reach. But it still might take a week or more to figure this out, which means Congress appears to be on track to take action on Syria next week at the earliest.

The Senate starts at 10 a.m., and is only scheduled to continue debating their resolution, S.J.Res. 21. Reid's decision to delay consideration of the language until Wednesday already makes a final vote likely by next week, not this week.

In the House, members may engage in some light debate on Syria. But it has no votes scheduled on the issue, and GOP leaders have not said whether they would consider Senate-passed language or take up their own proposal.

Members of the House will, however, consider up to eight suspension bills on Tuesday. They are:

— H.R. 1155, the National Association of Registered Agents and Brokers Reform Act,

— H.R. 2747, the Streamlining Claims Processing for Federal Contractor Employees Act, giving the Department of Labor responsibility for paying Davis-Bacon wage adjustment claims,

— H.R. 1891, the Science Laureates of the United States Act, creating a Science Laureate of the United States, an expert in the field who would "inspire future scientists,"

— S. 130, the Powell Shooting Range Land Conveyance Act, conveying land to a recreation district in Wyoming,

— S. 157, the Denali National Park Improvement Act,

— S. 304, the Natchez Trace Parkway Land Conveyance Act, conveying land to Mississippi,

— S. 256, amending public law related to the Northern Mariana Islands, providing parity with Guam, the Virgin Islands and American Samoa, and

— S. 459, the Minuteman Missile National Historic Site Boundary Modification Act, modifying the boundary of a South Dakota historic site.
