House Republicans and Senate Democrats were locked in a war of wills Monday night that threatened to shut down the U.S. government and leave a laundry list of federal services suddenly unavailable. Dow futures were up 33 points, though, as markets actually saw some upside to a shutdown. (What's the market doing now? Click here) The Senate wants a "clean bill" to continue funding the government after Monday, with no strings attached, while the House wants to tie any such "continuing resolution" to the defunding of the Affordable Care Act (AKA "Obamacare.")

12:07: That concludes this evening's liveblog. Please check back with CNBC.com throughout the evening for further updates on the U.S. government shutdown. 12:06: The Senate plans to take up the House's latest motions at 9:30 a.m. ET Tuesday. 12:02: Dow futures still up 26 points.



Meanwhile, networks have shifted from counting down to the shutdown, to counting up to mark how long the shutdown has lasted! 12:00: And there you have it. Capitol tweet 11:49: The OMB has issued a directive to government agencies, ordering them to "execute plans for an orderly shutdown." (Read the full directive here). 11:45: With 15 minutes to go, speeches are in progress on both the House and Senate floors. 11:40: A growing number of Washington-area attractions, including museums and restaurants, are offering free admission and other enticements tomorrow for anyone suddenly unemployed by the shutdown. (By some estimates the shutdown-related furloughs would affect 800,000 people). 11:33: Less than 30 minutes to the deadline. Presumably government agencies are now receiving their official notices that they will be shut down tomorrow, as per earlier reports on the OMB's plans. 11:29: The potential effects of the shutdown, large and small, are starting to become evident. Asteroid Watch, the Jet Propulsion Laboratory project that tracks large and small objects threatening to collide with Earth, made the following statement a few moments ago: JPL tweet 11:27: Rep. Chris Van Hollen (D-MD), of the House Budget Committee, calling out House Republicans for not agreeing to a budget conference in the spring. 11:21: House Minority Leader Nancy Pelosi invoking George Washington and his admonitions about political parties and government in a late-night news conference. 11:18: Not clear if the Office of Management and Budget will communicate its plans publicly, but it does maintain a Twitter account on @OMBPress. 11:11: Less than 20 minutes until the OMB has to start sending the orders out to shut the government down. As the Huffington Post noted, OMB Director Sylvia Mathews Burwell (a former charity executive who worked at the budget office in the 1990s) has suddenly become really, really important. Klapper tweet 11:03: Reid's "gun to our head" comment already breaking out as the line of the night. Being broadly taken as greatly diminishing the chances of a conference solution to the funding problem. 10:58: "We will not go to conference with a gun to our head. The first thing the House has to do is pass a clean six-week CR," Reid said, in reference to the continuing resolution to fund the government. 10:57: "This is a very serious time in the history of the country," Sen. Reid says on the Senate floor.

10:55: White House press corps reporting that they've been advised Pres. Obama won't be appearing on camera again tonight. 10:49: The communications director for Rep. Eric Cantor, the House majority leader, just tweeted that the House will in fact vote again this evening. 10:45: Still no word on whether there will or will not be votes tonight.



In the meantime, though, Secretary of Education Arne Duncan took to Twitter and did not pull any punches.

Duncan tweet 10:38: Now it gets confusing. Within the last 5 minutes, the Wall Street Journal tweeted that there would be another vote tonight, and the Washington Post tweeted that there would not. Less than an hour until the reported OMB deadline. 10:32: With more than 2,000 votes in, 58 percent of those taking CNBC.com's poll believe the government should be shut down tonight. 10:28: White House photographer Pete Souza tweets a photo of President Obama signing the legislation that ensures members of the military will be paid, even in the event of a shutdown. (Much being made by commenters of the open collar and choice of beverage, apparently a popular brand of iced tea). Souza tweet 10:17: The AP reports that 11:30 p.m. ET is the deadline for the Office of Management and Budget to notify agencies whether there'll be a shutdown tomorrow or night. So, T-minus 72 minutes now. 10:12: It's official now, the House GOP will move toward appointing members of a conference committee to negotiate a budget deal with the Senate. Not clear what that means in terms of a schedule for rest of evening or for a shutdown. 10:02: With less than two hours to go, the latest reports (via Chuck Todd) suggest House Republicans may propose a conference with the Senate to work out differences between their bills, a change in tactic that would still mean a shutdown. 9:53: Latest timetable notes via the @NBCPolitics team: Sen. Reid planning on being recognized again on the Senate floor around 11 p.m. ET.
